Re: [Bug 879334] Re: nfsd from nfs-kernel-server very slow and system load from 25%-100% from nfsd
Since then I have been forced to leave the ubuntu server platform and went to Redhat enterprise linux. Canonical needs to understand that these are critical bugs that should have been fixed in hours or days, not in weeks or months.

[Bug 1006446] Re: nfs4 causes enormous load in ubuntu-server making it unusable
@Christoph Bartoschek Any load over the number of cpu cores (X) is not acceptable. You have X camels. Each camel can carry one sack of flour. If you want to move more than X sacks of flour, some camels will have to make second trips. That is how `load´ works, right? Any load over X will make the performance collapse in some way. Throughput will level off or even decrease. You get time-outs or at least increased latency. Since you have 8 cores, even load 10 is simply way too high. 2x4 cores, 48 GB and gigabit? If these are only nfs servers, and for only 20 clients, they are way too powerful. You could serve 500 to 1000 clients on that. You probably run other service too? Web, mail etc? Of course there is no reason that the nfs daemons should cause so much cpu usage. 10.04 didn't, so why should that suddenly happen now? Your load should normally be far below one, for an nfs server. As far as I know, there haven't been major changes in linux's NFS stack in the last 3 -4 years, but there have been in the storage layer, such as IO scheduling. The fact that changing the scheduler makes the load go from 100 to 10 is telling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006446 Title: nfs4 causes enormous load in ubuntu-server making it unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1006446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1006446] Re: nfs4 causes enormous load in ubuntu-server making it unusable
All right, I am doing tests right now, but as far as I can see the 3.4.0-030400-generic kernel has the same behaviour as stock ubuntu 12.04. With ubuntu server and this 3.4 kernel: Test: - all workstation writing a separate 4GB file with `dd´ to /testhome, which is nfs4 mounted from an ubuntu server 12.04. Result: - all other processes started on the same machine, that want to read or write to the same mountpoint, after this dd began just block. for instance: ls just waits until dd is finished. commandline completion never finishes and the shell just blocks. - load on the server goes beyond 90, and nfs kernel threads consume lots of cpu. There is also a lot of io waiting, which is to be expected. - Also the nfs kernel threads are unevenly loaded it seems. There is a bunch (10-20) which use about 20-30%, and it tapers off to 3-0.5%. With RHEL6 server: Test: - same test, but to /data/misc, mounted nfs4 from redhat 6.3 server. Result: - processes started after dd began, wanting to read or write to the same mountpoint (/data/misc) block a few seconds but then start. for instance: ls waits for 5-6 seconds and then just answers. commandline completion waits about the same time and then completes the command or whatever it completes. - load on the server is also over 90, but the nfs kernel threads consume not so much cpu. Lots of io waiting. - nfs kernel threads are very evenly loaded. I see a long list of them using about 3% each. It goes up to maybe 5% and down to about 2%, and some of the 128 available threads are unused. I think more than half of them are active during the test. Keep in mind that this is a pretty heavy test (well I think it is anyway). But the ubuntu server already had big problems when the nfs usage is normal. Normal in our case means: - some people editing a few text files - a lot of people using web or mail, and therefore their firefox cache and the mail server accesses nfs-mounted /home/$USER/Maildir - some people doing heavy calculations and writing either a lot of small files or a few big ones. Small means about 1MB, big means several GB. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006446 Title: nfs4 causes enormous load in ubuntu-server making it unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1006446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1006446] [NEW] nfs4 causes enormous load in ubuntu-server making it unusable
Public bug reported: Problem: -- I just had to remove ubuntu server 12.04 to install redhat enterprise linux 6. The intermittent slowness was completely unacceptable for the users, who have workstations with /home mounted with nfs4 on this server. The mail server, also accesses the /home because the /home/$USER/Maildir directories are there. Using nfs4, the kernel nfs threads caused enormous load. The users had frozen desktops (greyed out windows) and mail slowed or arrived days later as a result. With RHEL6, all nfs4 problems are completely gone. I used the exact same /etc/exports file, and the same settings and mount options on the workstations, the same number of nfs threads. Both the redhat and ubuntu systems are KVM virtual guests on an redhat 6 virtual host (one of 3 actually). The storage backend is a very fast equallogic array, which exports iscsi targets to the virtual hosts. I am sorry, but I have to conclude the current nfs4 implementation of ubuntu server 12.04 is NOT fit for use. A complete university department suffered for weeks while I tried to solve the problems with ubuntu, but in the end it was decided to install redhat instead, re-using the same iscsi targets for system, home and data. A missed chance for ubuntu... Therefore I urge Canonical's people to classify this bug as critical. Also I think quality assurance should have caught this bug before shipping. Analysis LOAD: The nfs threads cause the kernel to use enormous amounts of 'sy' time as measured in top. I will attach a sample of top's output, of a particular _quiet_ time on the network. Load is 7.82. On busier moments, the load went through the roof, beyond 50 and further. It consumes actual CPU cycles. Each thread consumes upto 30% of a cpu core. I enabled 128 threads. rx an tx block sizes are 32768 on the clients. Both server and clients used async, both on redhat and ubuntu. SYSTEM vs IO-WAIT: The replacement redhat system can surely be overloaded, but then it does not consume CPU cycles doing so. Top does report high load, but it spends in in the 'wa' state. This indicates it is simply waiting for its backend iscsi devices to complete writes. I tested this by simultaneously letting all workstations write multi-gigabyte files with dd to /home. On ubuntu, the nfs threads spend their time in 'sy', doing who-knows-what. LOGS: Nothing at all appears in the logs. But when I set bitwise debug options in the /proc/sys/sunrpc/*debug files, lots of log entries appear. Those seem like normal NFS protocol messages to me though. I also tried to discover what was happening with wireshark, but the traffic looks like normal nfs4 traffic to me. SLOWNESS: That is the thing. The ubuntu nfs server is actually NOT slow at all. During my dd tests, it wrote half a gigabyte per second to its iscsi backends. It's _throughput_ is better than that of the redhat server. As far as I can tell, it falls down because it makes client side processes that want to do IO wait on other writes. A simple 'ls' has to wait until a write has been completed. And both server and client used async nfs. People's firefoxes freeze all the time because firefox need to read and write a lot to its cache and other files in the .mozilla directory. The dovecot imap server almost grinds to a halt trying to write all those little files in people's /home/$USER/Maildir's. The problems go on and on. Basically, a complete network of workstations is almost unusable because of this. Upfront tests were done of course, but showed only the excellent throughput but not the appalling `waiting´ behaviour. With redhat 6 there is no such problem. SITUATION: People use their own, and each others linux workstations for science, doing large calculations and writing a lot of big and small files to nfs. The nfs server serves /export/home, and also raw data storage from /export/data with nfs4. The clients mount those under /home and /data/misc respectively. Also there is a read-only software mount for certain scientific packages.

[Bug 1006446] Re: nfs4 causes enormous load in ubuntu-server making it unusable
You realize this server has been decommissioned, right? I can no longer do real life test on it. What I can do is give it a disk (well virtual disk, it's iscsi) and export that to all workstations and test with that. Just what I that in pre-production testing.

*** This bug is a duplicate of bug 220961 *** https://bugs.launchpad.net/bugs/220961 I just downloaded the oneiric server iso, and tried to install oneiric on a KVM virtual machine. It fails with writing the linux- image-3.0.0-16-server package, where it tries to write some kernel modules (.ko file). By switching to virtual console 4, I could see the error message, which is: No space left on device. This is in error, as there was plenty of space on all of the filesystems. All had the btrfs, except /boot, which had ext4. In the end, I could finish the installation by letting the installer choose its own partitioning, and choice of filesystems. This time around, the system has lvm, with separate filesystems for /, /usr, /var, /tmp and /boot. And swap. /boot is now ext2, and all others except swap are ext4. But now, after installing and logging into the system, apt-get dist- upgrade fails with the same error: No space left on device. Again in the same linux-image package. So now I cannot dist-upgrade. So it does not seem like a btrfs error to me, since the same erroneous `No space left on device´ now happens again. No filesystem is full, /var is only 14% full, and all others less than that. I think the error is somewhere in the apt system, maybe in the way it calculates disk space, or possibly the error is in the linux-image package itself. I really do not understand why this bug is closed and marked Won't Fix. After all, how is it possible to succesfully install if you simply let the installer run its course? It will fail every time.

It crashes every time with installing the same package: linux-image-3.0.0-. I tried with btrfs, and my own custom partitioning. This did not work so I tried letting the installer choose lvm and its preferred choices of filesystem sizes and type: / 322 MB, ext4 /boot228 MB, ext2 /usr 5635 MB, ext4 /var 2816 MB, ext4 /tmp 368 MB, ext4 /home 5780 MB, ext4 See? no btrfs this time.

Could it be that update while installing was ENABLED for all systems affected by this bug? If so, it would corroborate my theory that it is the linux-image-3.0.0-... package which is at fault. During my second try at installing, I did not have this enabled, I think. So if I'm right, it makes sense that I stumbled over the bug during apt-get dist- upgrade.

[Bug 881380] Re: bonding and vlan configuration options should really be available during ubuntu-server installation
I second this. In a typical virtualization environment, you have a server with several real network cards. These are typically combined in a bond device. On top of these you have bridges, and on top of those you have vlans. Virtual servers may exist in different networks, so you need this stacked solution of vlan, bridge, bond, nics. Also bonding should work with different lacp modes such as those available in CISCO switches, or others. It is totally unclear from the documentation how to do this. There should be tested, failsave documentation for the /etc/network/interfaces file. Right now it is nearly impossible to get exactly right. And even when I get it to work, the network does Ideally you should be able to do all this from within a GUI, but at the very least the documentation for the interfaces file should radically improve. I hope Canonical realizes this is CRITICAL for a virtualization server product. A single gigabit line is not enough, so you MUST be able to configure bonding, bridging and vlans easily. As long as this does not work reliably, you can just forget about ubuntu server. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881380 Title: bonding and vlan configuration options should really be available during ubuntu-server installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/881380/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So, adding a file `hostname´ to /etc/dhcp/dhclient-exit-hooks.d/ with this in it: # = begin /etc/dhcp/dhclient-exit-hooks.d/hostname == if [ -n $new_host_name ] then echo $new_host_name /etc/hostname /bin/hostname $new_host_name fi # = end /etc/dhcp/dhclient-exit-hooks.d/hostname == _kind of_ works to fix this problem. But on text consoles it still reads `localhost login´, and only after actually login is the hostname there on the prompt. Ugly. So it is not a complete fix.

What I expect to happen:
---
With client configured with empty /etc/hostname, and main network
interface configured for dhcp, I expect the hostname to be set during boot.
What happened instead:
---
With empty /etc/hostname, the machine comes up with (none) as hostname,
with /etc/hostname missing entirily, the hostname is set to `localhost´
Elaboration:
---
In networks with lots (dozens or hundreds) of linux workstations I keep the
/etc/hostname on each of them empty. They get the hostname from dhcp at
boot-time and set it. Managing lots of clients or a HPC cluster becomes
impractical if I have to set all hostnames on them by hand. Installation in
such a situation typically happens from an imaging host, where one or maybe a
few images is used to install on hundreds of clients.
So there must be NO host-specific configuration in these images. Hostnames are
set by the dhcp client with information provided by the dhcp server. UUID's are
NOT used in /etc/fstab, /boot/grub/grub.cfg, /etc/grub.d/*, or within the
initrd.img file. Instead device files are used: /dev/sda for instance. The
kernel commandline
root=UUID=db662660-94f7-4e94-8ed4-785fa9938ad0 ro quiet may be correct for the
_image_ but not for the client it is copied to! Yes, I could figure out with
blkid and script it so that the UUID for the client will be correct in various
places, but that is not what I want, it is too error-prone.
I want to be able to configure in /etc/default/dhclient that I want to
set the hostname as provided by the dhcp server, and in
/etc/default/grub that I want to use device files, not UUIDs.
Unfortunately Canonical gives me no such configuration options at this
time, and this is not good for sysadmins like me who need tools to
administrate lots of workstations.
Also note that dhcp clients can push a client side provided hostname to
a dhcp or dns server, which is useful if you have a laptop that the user
has root-access to. My situation is the other way around: the users have
NO root-access on the workstations or the HPC cluster, and hostnames are
centrally pushed to the clients.
For this latest dhcp host-setting regression I suspect two reasons.
I suspect two reasons:
1) upstart sets the hostname in recent ubuntu distros, and it simply does:
exec hostname -b -F /etc/hostname
This will not work if /etc/hostname is empty!
2) dhclient does not set the hostname despite being so configured in
/etc/dhcp3/dhclient.conf
Apparantly it is possible to write an exit hook script that sets the
hostname like this:
# = /etc/dhcp/dhclient-exit-hooks.d/hostname ==
if [[ -n $new_host_name ]]
then
echo $new_host_name /etc/hostname
/bin/hostname $new_host_name
fi
Apparantly $new_host_name is the internal variable that dhclient uses for the
hostname info that it got from the dhcp server.
The correctly configured dhcp server has stanzas for the clients like this:
host maris007 {
fixed-address 10.0.0.7;

[Bug 835790] Re: kexec does not work in natty as a kvm guest
To add why this is important to me: I use a virtualisation host as a platform for distributing images to networked workstations. So I run image machines as guests on the virtualisation host, and run tests of installing those images in other virtual guests. Using pxe, I load a kernel, initrd and an installation script, and do all partitioning and installation from this script. I then use kexec to start the distribution kernel of the just installed (virtual) or updated machine. The idea is to turn on a computer (real one) and have it install and then boot into the newly installed or updated system. So I need to test this install system on virtual guests. If kexec does not work for natty and oneiric, this rather throws a spanner into my whole installation system. Kexec is not some unimportant and esoteric idea for me and other people.

[Bug 672438] Re: cups upstart post-start script hangs forever when local socket is disabled
@Martin Pitt,
I did some more debugging. What I did is try to move a working cups
config from a redhat server to a new ubuntu natty server. So I stopped
cups, renamed the ubuntu /etc/cups to /etc/cups.ubuntu. The new config
dir was /etc/cups.lorentz, and I made a symlink
/etc/cups-/etc/cups.ubuntu. This is when start cups quits working, and
starts looping in /etc/init/cups.conf. It loops through the entire
script by the way (pre-start, post-start and possibly also exec cupsd
-f), not just the post-start. The cups.lorentz config also has a Listen
/var/run/cups/cups.sock line, so that is not the problem. I think that
it has to do with apparmor not liking a link instead of a directory at
/etc/cups, or something like that.
When I just rename the /etc/cups.lorentz directory to /etc/cups
(removing the link first), start cups suddenly works.
With the link in place, start cups just keeps looping, which is a bug.
It should either just work or give me some apparmor complaint if links
to config files or directories are not OK. If it is an apparmor issue,
replacing config files/dirs by links is likely a problem for other
services as well, like ldap, nfs, fstab etc.
I thought there was one obvious bug in your loop in /etc/init/cups.conf: you
forgot a $ in the arithmetic expansion.
Your line is: timeout=$((timeout-1))
which I thought would never work, and it should be something like this:
timeout=$((${timeout}-1))
But. I just checked and it seems your line actually _does_ work. Even with the
missing $. I can't find that feature in the bash man page.

The echo statements writing to /tmp/TEST are my additions. After running
start cups, waiting half a minute, /tmp/TEST contains the following:

So, it never arrives at the echo after a while... line I added, but
the post-start script seems to get executed again and again.

[Bug 652503] [NEW] Bluetooth applet crashes
Public bug reported: Bluetooth applet crashes while trying to connect a bluetooth audio device. Jabra BT8030 Can connect to headset function, but it never works. Cannot connect to audio function, and applet crashes. While being greyed out (using compiz) the desktop is mostly frozen. Can move the mouse, but cannot click anything. The audio device is (mis)recognized as (NULL). It works fine with my android G1 phone, and with a Mac Mini. The little bluetooth dongle I use works fine with my Logitech Cordless Mediaboard Pro, so at least some part of the bluedevil software (or whatever the little applet in the Indicator Applet is called) seems to work OK. This bluetooth headset has never worked with ubuntu and still doesn't. The keyboard also used to not work, so I'm pleasantly surprised that seems to somewhat work now. Somewhat, because it does tend to lose its connection when the keyboard goes into a low power or sleep mode.

Re: [Bug 141613] Re: npviewer.bin crashed with SIGSEGV
That's not a fix. That is called a workaround. The fact is, there are still multiple bug in this 32-in-64 wrapper thing. Because of the severe problems people were having with this, choking up their linux workstations, I banned it from the network altogether. I needed it for acroreader and flash. They do not provide proper 64-bit versions, or uptodate versions of their product. No 64-bit acroread at all. Okular or evince is good enough as a pdf reader plugin, and for flash there really is no proper substitute. I hope some company will give some funding to bring Gnash up to the level of support that the windows platform enjoys. I lost all faith in good things coming from Adobe. No photoshop for linux, no proper flash, no proper pdf reader, let alone creator. Still Adobe is an important provider of standards like PDF, flash, postscript, so I hope that they do get their act together soon. They are too important for linux indirectly to die. Otherwise I would not care about them.

[Bug 90388] Re: hostname supplied by dhcp server is not used
Hello?? It used to work in Hardy!!!

In a network of Ubuntu workstations, I want to: * set hostnames from the server, via DHCP. NOT the other way around, i.e. let the client change the DNS server records. I do not want to have to create lots of little scripts like in the solution of Christoph Dwertmann for something that used to work without all that. * I do not want to have network manager at all in managed clients. The users are not allowed to alter the network settings, the network is configured once at boot via dhcp and that is that. No network-manager needed. Make it removable. * be able to use a single image to roll out to clients. This means that UUID's are not handy to have in /etc/fstab, or in the grub config files. The UUID of partitions in the master image will be wrong for the clients. I do not want to have to fix all the places in /etc/fstab, /boot/grub/grub.cfg, /etc/grub.d/*, the initrd file even, to replace the UUID for the clients UUID's.

[Bug 523188] [NEW] Make it possible again to let dhcp server set the client hostname
Public bug reported:
This is an important option for managed workstations like in universities and
such.
In Hardy it was perfectly possible to let the dhcpserver set the clients
hostname. In the server dhcpd.conf you can set hostnames for the clients like
this:
host appel {
fixed-address appel.lorentz.leidenuniv.nl;
hardware ethernet 00:13:d4:c2:2a:de;
option host-name appel;
}
of even easier:
use-host-decl-names on; # This tells the server to provide the name
after host as a hostname to the client
host appel {
fixed-address appel.lorentz.leidenuniv.nl;
hardware ethernet 00:13:d4:c2:2a:de;
}
In Hardy the dhcp3-client package used to pick this up perfectly, and
the client used to set its own hostname. Now in Karmic it no longer
works. I have to remove dhcp3-client and replace it with dhcpc to get
this functionality back.

[Bug 479956] [NEW] udev or kernel or both do not properly recognize Mac harddisk when connected via a SATA to USB adapter, while Fedora does.
Public bug reported: Description: A user came along with a Mac he spilt a drink in, and asked me to copy his harddisk to the network. I have this Serial ATA IDE to USB adapter, from conceptronic, which is a very handy gadget in which you can plug any harddisk and connect it to your computer via USB. Normally this works flawless with ubuntu. I do have the hfsplus, hfsprogs, hfsutils and libhfsp0 packages installed. Normally the disk is mounted automatically and I set up Nautilus so that it automatically opens a window for each partition found on a harddisk so connected. Only with this Mac harddisk, the system was not able to find any partitions. dmesg reported a USB mass storage device connected, but with fdisk -l it did not show up. However, with a fedora 10 machine, the disk mounted immediately and without problems. A copy was made for the user without any problems. So clearly this is an ubuntu problem. I am not sure where to file this issue, but kernel or udev seem to be the logical places to look for the cause. Maybe there is a different partitioning scheme that Mac disks uses, and which has not been compiled into the ubuntu kernel. Or there is some flaw in udev or its scripts which causes it to fail making the device files for the Mac partitions. Please put this bug in the right category: udev, kernel or whatever. I am not sure where the problem is, but I guess udev.

I have another problem with the unmount/mount dialogs in Nautilus, related to the bug. I have a USB stick with four partitions on it. Inserting it in a hardy desktop machine results in the machine mounting these four partitions nicely under /media/disk, /media/disk-1, /media/disk-2, /media/disk-3 respectivily. So far so good. But I only need some files from the first partition, so I unmount the other three using the right-click menu in Nautilus on them. Problem 1: In the sidebar, the icons for these three unmounted disks do not change, so I cannot tell if they are unmounted Problem 2: Worse, if I right-click on the disk again, `Unmount Volume´ is still an option, it is not greyed-out. Clicking it results in a popup which says Cannot unmount volume. The volume is not mounted. Unmounting it should not have been an option in the first place. Problem 3: I decide I need a file from partition 2 after all, so I need to mount it again, but there is no option in the right-click menu to do that. Problem 4: So, OK, I cannot convince nautilus to remount my partitions, so I manually find out which shells and programs are currently using the remaining mounted partition and close them, and now unmount the first partition. Then I remove the USB stick, wait a couple of seconds and re-insert it. In the current Nautilus window the four disks do not disappear when I pull the USB stick out. When I re-insert it, another four disks appear. Now there are eight! Four of them are non functional, and the other four are, but there is nothing to diffirentiate between them except by trial and error. The `reload´ button in the Nautilus toolbar also does not solve the problem. However if I start a _new_ nautilus window it does show the correct information. And if I go to `computer´ it shows me the four (not eight) partitions as disks, and right clicking on each of them presents me with a menu that has a unmount option. So re-inserting aparantly did result in remounting all partitions after all. At least in the Location:computer:/// part of Nautilus. So I right-click unmount them all again. Now the icons in the main pane _do_ change from a flat harddisk to a bulky rounded harddisk. In the sidebar the disks disappear. However, in other Nautilus windows they do not disappear. Also there is a problem in the Location:computer:/// interface, namely that disk I unmounted in it now have right-click menus that show both a mount and an unmount button! Anyway, this is problably a highly confusing bug report for anyone to follow, so I recommend anyone who reads this to try it out yourself with a few USB sticks, or else with a partitioned one (easier). I would characterize this bug as inconsistencies between separate Nautilus windows, the sidebars and the Location:computer:/// interface concerning the mounting and unmounting of removable media. -- When nautilus cannot unmount a media, it must tell why. https://bugs.launchpad.net/bugs/19586 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 19586] Re: When nautilus cannot unmount a media, it must tell why.
I totally agree with this issue in fact being a bug. Why? -- Nautilus provides a GUI in order to take things like save mounting/unmounting to preserve filesystem integrity down from system administrator level to everyday user level. I am a system administrator for 70 linux desktop, amongst other things, but a lot of people are defecting to Apple over issues like these. OS X _does_ give helpful information about which process is blocking umount, even if the process is running in a shell. Outline how to solve: - Using information from `lsof´ you can figure out which process is blocking the umount. Furthermore the PID can be used to identify the window or terminal (even text console) that belongs to it. DBUS can then be used to signal the window manager to bring the offending windows to the foreground. Signals can then be sent the programs to initiate the `save files´ dialog. In the case of text consoles or terminal windows the GUI can present a dialog to close the programs running from those shells or close the shells themselves. This is a solvable problem in most common cases, and actually I think quite straightforward. It just needs some scripts parsing lsof, some interaction between filemanager, windowmanager and dbus, and a bit of heuristics to cover the most common cases. This is a low hanging fruit in terms of improving the user experience. Whose responsibility? -- Enabling the average clueless user to unmount usb sticks is core functionality in a desktop OS. Since Canonical aims to offer an easy to use Linux distro, primarily based on Gnome, I think that this _core functionality_ should be provided by Canonical. Since Canonical is hiring people to work on kernel, X and Gnome/KDE, I certainly feel that you cannot simply say this is an upstream issue. Upstream has different priorities. Since this is probably a relatively easy thing to solve, no major new subsystem needs to be invented, just using existing subsystems and programs like `lsof´, I think Canonical should get involved with upstream to fix this once and for all. -- When nautilus cannot unmount a media, it must tell why. https://bugs.launchpad.net/bugs/19586 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 62195] Re: edgy update-grub destroys kopt
No worries, I was not trolling. I personally don't want to switch from ubuntu to anything else. It is true however that ubuntu sometimes does things that make sense for the home user, but not for large collections of workstations. This grub bug, or rather decision by ubuntu developers to overrule a user/administrator setting is an example of that. Ideally, I want to be able to set the default behaviour of update-grub in a /etc/defaults/update-grub file. In my opinion, ubuntu is mainly aimed at either home computers (incl. laptops) and servers, but not large scale client installations. There are virtually no ubuntu-made tools for sysadmins to do tasks typical for such an environment. I need stuff like: - configuring authentication for LDAP/Kerberos/Active Directory - account administration (adding, removing, changing accounts, archiving data, quota settings, etc.) - making a customized menu-system for all users, alacarte can only do it for single users - imaging solution to install clients over network that is simple yet configurable - per-user settings for thunderbird, alpine, firefox extensions, numerous other applications - some kind of central store for images, like git or subversion, combined with a virtualization solution in order to build images and test before installing them on client machines. - I would be willing to pay for a service by Ubuntu to build deb packages for unpackaged software like for instance `xv´. Every time I need to upgrade the client workstations, I also need to hunt for around 40 or so software packages, not present in the repositories. Ubuntu might be able to make some money to provide a packaging service for people like me.

[Bug 62195] Re: edgy update-grub destroys kopt
I use a workstation as an image for a number of other workstations, and install and update those with rsync. So, if I upgrade the image and a new kernel is installed, update-grub is run. This means that the UUID in menu.lst will now be spread by rsync to all those other workstations, rendering them unbootable when they go down. This means I must have simple device names in menu.lst, not UUIDs. Please make update-grub NOT overwrite any # kopt=root=/dev/sda6 settings I have made. Please, in general, do not try to overrule systemadministrators, as you will only make our life more difficult and in the end force people like me to install another distro like SuSE of Fedora over Ubuntu. Because that is what my boss will decide if I have to spend too much time on crap like this when I upgrade the images. Remember that Ubuntu is not only used by Joe Linux @ home, but also by universities, schools and other institutions that need an imaging solution.

[Bug 156085] Re: Could not open /proc/bus/usb/devices
I have a Trust media center keyboard with builtin trackball. After a reboot, suddenly the trackball responded very sluggish, like with a ball-mouse (not optical I mean) with dirty wheels inside. But it couldn't be dirty yet, it is brand new. I noticed earlier that usbview did not work, but used to under Gutsy. I mounted the /proc/bus/usb filesystem, with mount -t usbfs procbususb /proc/bus/usb and instantly the trackball is working again. Usbview too. Whatever the thinking is about /proc/bus/usb, the change that was made to it broke my mouse (well trackball) and probably breaks the X window experience for lots of Gutsy users. Also there should be a better program than just usbview in Gnome to work with usb devices. usbview is very limited. And ugly. -- Could not open /proc/bus/usb/devices https://bugs.launchpad.net/bugs/156085 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 154366] Re: need word-wrap option
Hello Alexander, you are right of course. I know it is not a bug, but still I would like to have this word-wrap function to deal with problematic websites, as you say. Please consider this a feature request. Firefox naturally has word-wrapping built-in; I just need an option to apply it to a selection of text, or to a certain page or frame or whatever. I was kind of hoping this request would bubble upto the right person if I submitted it as a bug. best wishes, Roland Nagtegaal On Wed, 2007-10-24 at 10:13 +, Alexander Sack wrote: this isn't a bug in firefox, but a problem of the website.

[Bug 154366] need word-wrap option
Public bug reported: Binary package hint: firefox In many web pages, such as this one: http://lists.freedesktop.org/archives/compiz/2007-October/002726.html, I encounter sentences with no end-of-line. This results in very long lines, that run out of the viewable window, and I must use the scrollbar to read the whole sentence. Sometimes the whole text is on one line. It is very inconvenient and makes such text almost unreadable. To fix this, firefox could include an option in the right-click menu to word-wrap lines that run out of the window. Wrapping too long lines does not have to be the default behaviour, but having it as an option would be very handy. I'm sorry, this is not a bug persé, but I hope someone will pick this up anyway.
