Have you checked to see if the sites you use have an interface for mplayer or another media player? (Assuming they are streaming services similar to Youtube) If not, it may be simpler to use nspluginwrapper. Gnash compatibility can be spotty, but is improving. If you suspect that the services that you use don't use advanced/recent Flash features, give gnash a whirl. The last time I used gnash, it was completely fine for basic streaming stuff, but marketing sites and tech demos and (some) Newgrounds material was borked. But that was over 3 years ago; times have certainly changed, and I'd wager for the better. :) Good luck. Use Gnash with Lightspark. That's actually a supported combination. Last time I used them, they supported different versions of Flash (AVM1 and AVM2). If what annoys you in Firefox is the interface, you can also try some addon that offers an alternative interface (uzbl screenshots look a lot like firefox with pentadactyl) [not trying to get into a flame war, really just suggesting something -- at least here (normal amd64) I can use flash in firefox] -- Nuno Silva (aka njsg)

The problem there isn't in the udev code, but it has to do with what is happening in rules that other packages install. As I recall, the problem is where the ebuild choses to install the code. Putting the udev code under /usr forces the issue on systems where it would otherwise not be an issue. Putting the udev code under / avoids that issue, but opens up the system to the silently fail thing upstream liked to use as the basis of separate /usr is broken So, there are three conceivable configurations (initramfs notwithstanding): 1. With systems which don't require /usr binaries before /usr would be mounted, separate /usr is not a problem. 2. With systems which require /usr binaries for some features before /usr would be mounted, those features will silently fail. 3. With systems which require /usr binaries to mount /usr, all hell breaks loose. Putting the udev code under /usr moves all udev systems from group 2 into group 3. In a sense, this fixes those systems because the admin is forced to address the silent failures he was previously unaware of. It also means pissing off a bunch of people who had features silently failing...but they probably didn't know or care about those features in the first place. It also moves all systems from group 1 into group 3...which is simply wro= ng. So long as eudev keeps its install path at / instead of /usr, admins in group 1 will probably be perfectly happy.

Ok, just read the new news item and the linked udev-guide wiki page, and
the only thing left that I'm unsure/concerned about now is the
persistent net rules changes...
The very last line on the wiki page says:
4. Known problems
Stale 70-persistent-net.rules (or other network rules) in
/etc/udev/rules.d can prevent the predictable network naming from being
enabled. Both 70-persistent-net.rules and 70-persistent-cd.rules are
from the now deleted rule_generator
These 'stale' 70- rules are all I have right now (again I'm still on
udev-171-r10), and while the wiki page doesn't say what to do with/about
them, it seems to hint that I could leave these in place and... they
would still work as they did previously (prevent the predictable network
naming from being enabled)?
My system (8+ years old) has a Tyan motherboard (S2895) with dual Gb
ethernet ports, with only one port currently used (but both are enabled
in the BIOS so both are listed in my current rules file).
(And, more importantly, they're seen and handled by the running kernel.)
[...]
Contents of 70-persistent-net.rules:
# PCI device 0x10de:0x0057 (forcedeth)
SUBSYSTEM==net, DRIVERS==?*, ATTR{address}==00:e0:81:54:9c:8b,
KERNEL==eth*, NAME=eth1
# PCI device 0x10de:0x0057 (forcedeth)
SUBSYSTEM==net, DRIVERS==?*, ATTR{address}==00:e0:81:54:9c:8a,
KERNEL==eth*, NAME=eth0
So... after reading the new news item, am I right that all I need to do
to make sure that my network comes up properly is... edit the 80-*
rule(s) that are created after udev is updated to make sure the same
adapters that were named eth0/1 are now named net0/1, and the kernel
will now take care of naming net0/1 eth0/1?
You can either remove it and get what udev gives you (a bit more
cryptic, but it is supposed to be somewhat persistent unless the cards
are moved around, or there are major kernel changes), or you can give
them the names you want, as far as it's not ethX.
But you will always have to update other config files (firewall, init
scripts, etc.) to have the new names.
Also, is it critical to remove (or at least rename) the old 70- rules
*before* the update, or just be sure to do so before I reboot after the
update?
No idea, I'd expect it to be only needed for the reboot, but I don't
know udev *that* well.
Thanks - I'm sure I'm just being paranoid, but it has helped me to avoid
lots of pain in the past with other major updates on this system over
these last 8+ years.
(I'm not concerned about the cd rule because obviously that won't affect
the system booting, so I can come back and fix this one later if needed)

My kernel config is maintained along for years now and has survived several hardware changes. I don't have any obvious problems but I wonder if I have something in there that is deprecated and might be better thrown out. I don't use anything other than stable code releases from portage, but even then I usually do make oldconfig, followed by a by-hand inspection of the options with make menuconfig, to catch stuff that got through me in make oldconfig, and to see if there's any change in other options that I want to tune. Does it make sense to take the .config from the gentoo install dvd for example and remove all the stuff I don't have? Maybe still too much enabled options in the end. Even then, if you do that and tune the config several times, you'll likely end up with a lighter kernel. Just drop anything you don't need from the device drivers. make allnoconfig as a start? That is probably much better than the config from the install dvd, yes, in fact most of the work coming from an Add-It-All config is that you have to disable many, many entries. allmodconfig ? I'd go with allnoconfig, although if you compile lots of stuff as modules, you can then check lsmod to see what does, in fact, get loaded.

I've heard (or read) that before, to me it seems quite strange that one of the main products from MS to be so outdated in this area. AVI has been around a long time. It is inevitably prone to bitrot, then. AIUI the AVI specification states a number of valid codecs that can be used; AIUI h264 (for example) is not amongst them. It will work on some systems (particularly open source) to put h264 / AAC into an AVI - that's not supported on others. So if you need to play the video on a Mac, a games console or a set-top box then you may be in trouble. As a rule of thumb, most new video-playing devices have hardware h264 support; use .mp4 or .mkv for h264. IIRC, h264 is actually one of the codecs that has issues with AVI. See http://en.wikipedia.org/wiki/Comparison_of_container_formats. I tried an MP4 renamed as AVI, and it worked. If you merely renamed the file then you didn't change the container. http://html5.xoofoo.org/video.html A Linux video player will probably ignore the file extension - it'll figure out what kind of container you used based on the file's header bytes and on the file structure. The default video player installed on Windows or Mac may not be so clever. This is probably more about Microsoft Powerpoint being actually able to deal with other containers (it probably merely passes the video file (container and everything) to the Video for Windows or DirectShow subsystem, which may or may not have handlers for other containers). I guess that, although Powerpoint does not need to care about the container, it does enforce some extension. -- Nuno Silva (aka njsg) http://njsg.sdf-eu.org/

The topic under discussion is solutions to the problem of not being able to do exactly that. Then I suppose you can surely explain in a nutshell why can't init scripts simply do that? Because certain people with influence have rearranged the filesystem so that programs within /usr are absolutely necessary for booting; they are needed _before_ init has a chance to mount /usr. So either /usr has to be in the root partition, or crazy kludges need to be used to mount /usr before the kernel runs init. I surely don't know the udev architecture well enough, but if this is all done by the udev daemon, can't we just mount /usr before the daemon is started? The only needed things should be mount (which is under /bin here) and /etc/fstab. and a device node in /dev - like /dev/sda2. And how do you get that one without udev? oops?

This news item is to inform you that once you upgrade to a version of udev =181, if you have /usr on a separate partition, you must boot your system with an initramfs which pre-mounts /usr. An initramfs which does this is created by =sys-kernel/genkernel-3.4.25.1 or =sys-kernel/dracut-017-r1. If you do not want to use these tools, be sure any initramfs you create pre-mounts /usr. Also, if you are using OpenRC, you must upgrade to = openrc-0.9.9. For more information on why this has been done, see the following URL: http://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken You can read that systemd is *THE* problem, not udev, and that until the primma donnas fubared udev by jamming systemd into it, There Was No Such Problem (TM). And that explains where the train jumped the track... No, actually it doesn't. It just has the same kind of very generic claim that has been repeated several times in this thread (which is why? because it won't work) and links to an article that explains why some udev rules would silently fail for all this time (for *years* now, I'd guess).

On 2012-12-25, Michael Mol wrote: Now, question: could I not create a /usr service and make things dependent on /usr come after it's been mounted? That seems the single, core missing piece. This suffices for /usr on regular partitions. The problem is with more complex stuff which, I assume (assume, because nobody who actually has that setup has actually explained what happens), requires device files which are not present under /dev by default, and, even if /dev is already mounted once init is started, it only has a handful of default files. The additional, non-default files for most of the stuff are nowadays created through udev, and so you need to have udevd running and processing events to populate /dev. Thus: - The already existing rules will silently fail problem will not be solved, as some events will get processed before you have a chance to mount /usr - The udev won't work because it is under /usr issue, which seems to be the case of udev since it got merged with systemd (once again I'm assuming here, from a bug report)), well, this one is not easy to solve unless you copy the udev tools to / or to some initr*, or you install udev to /. But, of course, for /usr on regular partitions, just issuing mount /usr before starting udevd works. -- Nuno Silva (aka njsg) http://njsg.sdf-eu.org/

Thanks. So you don't have udev-181, but you already need stuff under
/udev for these rules to work. Which is what that URL is about.
I will not allow my system to upgrade to anything listed in the new
item. I'm not going to chance it.
As to a silent fail. I watch my system really close when booting. If I
see any error message, I hit Scroll lock and make a note of it. I have
one now about rc.conf. I have the file in the new place but have not
rebooted yet to test. So far, I have not seen any error except for
sound card stuff when booting. Since a sound card is not needed when
booting, I'm not worried about it.
You happen to understand that the silent part in silent fail implies
that you won't see any error message? If it wasn't silent, it would not
be called silent fail.
In fact, I'd say that the article the URL points to was written exactly
because this has been this way for some time, but as the fail is silent,
many people simply don't notice that it fails, and assume that, as far
as the system reachs the login prompt with no visible errors, then
everything is OK.
Again, this comes to this that has been around for decades. Anything
needed for booting, should be on the / file system, /bin, /sbin, /lib or
/etc. Nothing needed for booting should be placed in /usr or /var since
a lot of people put those on separate file systems, including me. What
I don't get is this, that has been working for decades so why change
it?
Then perhaps you should do, for example,
equery belongs '/usr/bin/hp-check-plugin'
equery belongs '/usr/bin/python'
equery belongs '/usr/bin/hp-mkuri'
equery belongs '/usr/sbin/alsactl'
[and so on, for executables and scripts used in the udev rules the
command found on your system]
And file bugs on these packages (ALSA, python and perhaps some CUPS
drivers?), as these commands are needed for booting (they're called by
udev as soon as there is a device matching the rule) and, so, they
should live under /, not under /usr.

(With the case of a regular partition being no problem just because linux apparently offers hardcoded files for some partitions in the first ATA controllers.) Well, so far I have stuck with the udev that works without a init thingy. I do have a init thingy for when the udev that requires it is marked stable. The devs are keeping the udev that requires /usr on / masked and/or keyworded until everyone is ready. That was until eudev was announced. Now they are also waiting on eudev to get stable so people can switch to it. I plan to switch too. The problem is this from my understanding. For decades, any commands or config files needed to boot Linux had to be in /bin, /sbin, /etc, and/or /lib. Those directories were what was needed to boot and anything needed to boot a system should be installed into one or more of those directories. Then someone came up with the idea of putting things into /usr instead. When they did that, it broke things. To me, this change makes as much sense as putting the mount command is /usr/bin but that is where some want Linux to go. I have read where some want to basically move about everything to /usr but not sure how much traction that is getting. From my understanding, the problem with udev was that the rules used to process events may require stuff from /usr. Which is OK, as I think the rules may even end up executing random executables. And the sole problem with this is that udev will not wait, it will simply fail in a silent way when applying rules that require stuff from /usr. Now, also, from my understanding, this was already the case for some time (maybe even years?). And that's why I've asked for more details. So, if the udev you use is OK with no initrd, what is in the new udev that actually requires the initrd? Meanwhile, I found https://bugs.gentoo.org/show_bug.cgi?id=446372, which would explain why, all of a sudden, there is a bigger problem. Now, I wonder how is this solved with an initrd, by copying udevd there? If so, why don't we simply install udevd under (or copy its stuff to) / instead of using /usr as $PREFIX? Basically, something that has worked for decades is declared to be broken all that time and if it wasn't broken, we are going to break it. ... yeah... the thing here is that I'm just trying to separate the upstream comments on separate /usr is broken from the actual thing that breaks the boot process. So far, even the stuff from freedesktop I've read stating that separate /usr is broken do not seem to mention that udevd is moving to /usr. From my understanding, if I upgrade my system to the later version of udev and bypass the init system, my system will not boot. I have not tested the theory but that is what people have been saying.

The command I issue is: emerge gentoo-sources and the output of the command is this: http://bpaste.net/raw/66293/ The only thing I can really read from the error message is that it runs out of ram. This surprises me because all it is really doing is moving the kernel sources into place? I asked around in #gentoo on irc.freenode.net and someone adviced me to turn of MAKEOPTS=-j2 and -pipe, but this doesn't fix it. No surprise here, from what I can see, what's happening is that *emerge* is running out of memory, it's not a compilation, so -pipe or MAKEOPTS won't make any difference here. Are you, by any chance, running anything else on the machine, or maybe you forgot to enable the swap? Even then, unless emerge has changed a lot in the last few years, I doubt you need that much memory to have emerge copy files to /. But check the output of free -m or something like that to check whether 1) there's something else using a lot of memory and 2) the swap is effectiely enabled. The possible work around I have thought of is just getting the vanilla kernel from kernel.org, but the gentoo wiki advise against it, since gentoo-sources is a patched kernel. You can install the vanilla kernel, I think you can even use emerge for that, but I also think your problem here is with emerge running out of memory, not gentoo-sources being incompatible. I'd try to fix whatever the emerge issue is as it will probably prevent you from installing other packages, and that is effectively a major issue when you want to use the system.

I had to re-size the pictures add background music etc. DVD only holds 4GB USB sticks have larger capacity. It depends a lot on the TVs you want to play the slideshow in. If it's a specific TV, you can just check what does it support. I've seen some LG TVs which were able to browse photos on USB mass storage devices, and they probably had a slideshow feature, although I've never tried that. If you're aiming at broader support, your best chance is really some widely supported set of settings like DVD-Video, because some table DVD players (and TVs too, I guess) will be picky regarding framerate, frame size, codec and other settings. For example, technically you could grab some file container and codec, set the framerate to the time you want between photos and just use the photos as the video frames (I think ffmpeg allows you to do this, but some containers have problems with exotic framerates). But I guess many TV and table DVD players out there would just refuse to play that. One thing, though, is that what only holds ~4GB is *a specific* format of DVD media, there are DVDs with larger capacities, and I'd not be surprised if the size was not restricted at all by the DVD-Video standard (the file format, filesystem structure and codec specifications, not the physical medium specifications). -- Nuno Silva (aka njsg) http://njsg.sdf-eu.org/

The other reason that stems from that time period is the size of disks we had back then - they were tiny and often a minimal / was all that could really fit on the primary system drive. Gradually over time this setup became the norm and people started to depend on it, and more importantly, started to believe it was important to retain it. It's their right to believe that. Recently I decided to measure if I still needed a separate /usr (I was a long time advocate of retaining it). I'm in the lucky position of having ~200 Linux machines, all distinctly different, at my disposal, so I trawled through memory and incident logs looking for cases where a separate /usr was crucial to recovery after any form of error. To my surprise, I found none at all and those logs go back 5 years. So I got to change my mind (not something I do very often I admit) and concluded that separate base and user systems (/ and /usr) was no longer something I needed to do - the system - disks, hardware and the software on the disks - was very reliable, and what I really needed was ability to boot from USB rescue disks. I did find, not unsurprisingly, that I also really needed /usr/local on a separate partition but that's because of how we install our in-house software here, plus our backup policies. It also goes without saying that these days we need /home, /var, /var/log and /tmp to all be on their own filesystem, and we need that more than ever. I thought I should just toss that in the ring for people who are undecided where they stand on the debate of separate / vs /usr. It's what I found on our production, dev and staging servers, plus a whole lot of people's personal workstations (sysadmins and devs). The environment is a large corporate ISP that defies categorization, we almost have at least one of every imaginable use-case for running on Linux except something in the Top 100 SuperComputer list.

Thanks for sharing your experience, and not just your emotions. One of my favorite quotes is, A man with an experience is not subject to a man with an argument. My thanks, too!

I'm using xfce4, but I'm not sure if I'm using a mirrored screen or an extended desktop. All I do is plug the laptop into the HDTV with an HDMI cable and hit the keyboard shortcut to switch screens which brings up a little dialog. There is nothing too complex here, if the TV and laptop are showing the same thing, one screen is *mirroring* the other, otherwise, if you see different things in different screens, you're using an extended desktop. I was able to change the resolution from 1024x768 to 1366x768 with xfce4's Display settings, but when I disconnect and reconnect to the HDTV it displays at 1024x768 again. Do you know how to select the output resolution for an external screen permanently? Is this done in xorg.conf? This is, I'd guess, a preferred video mode announced through EDID, where the TV, even if it supports 1366x768, will anounce 1024x768 as preferred. You could do the change with a small xrandr one-liner, and there must be some way to do it through xorg.conf, although I don't know how.

I can understand enabling swap on a laptop or other system with constrained memory capacity, but doesn't it make sense to disable swap and add memory on a 24GB server? Is swap basically a way to save money on RAM? No swap contains pages from memory that have not been accessed for awhile so they can be stored elsewhere freeing ram for actual active pages. When they need to be accessed, they have to be swapped back in, and often something swapped back out to make room for it. Like BillK said, it's not, whatever gets there must be swapped back in to be used again. For example, let's say you have a program that needs to open a really really big file, an 8GiB file (no FAT jokes, please), and you have 4GiB of RAM and 6GiB on swapfiles/partitions. The system will not be able to put the entire file on the physical memory (and it may not even be able to do so on virtual memory (memory as the process sees it), if you're on 32 bits, IIRC). This means, although the program can access the file data, and from its own point-of-view, all data is on memory, the system will have to do some swap-in-swap-out gymnastics every time the program wants a chunk of the file that's not on RAM. OTOH if you actually add 6GiB of RAM, you'll probably be able to do it all from RAM (8GiB for the file, and the other 2GiB for whatever else is running). It is better to see it as BillK describes - not a way to extend your memory, but a way to store not-that-frequently-used pages when you need to load something else.

LITE-ON_COMBO_SOHC-5236K is my internal drive, which SHOULD be mapped
to /dev/cdrom. But it's not:
camille rules.d # ls /dev/cdrom
ls: cannot access /dev/cdrom: No such file or directory
Check also /dev/cdrom*. Maybe it got another name, as there are at least
three rules to symlink that drive (if it matched all rules, udev would
create the three links, but the third rule looks different).
Why is it not being mapped correctly? Is the rule above not correct?
I've tried to read tutorials about writing udev rules, but the example
rules in the tutorials look nothing like the above rules, and I didn't
write those. I think they were created when udev was installed...

If you're using a recent kernel, it's probably udev which refuses to
process devices under the old ATA driver.
(I don't know if it *exactly* refuses, or if it's something else, but
the final result is what you see, no /dev/{cdrom,cdrw,...} link)
The problem, as far as I could figure out, is that the ID_PATH that udev
gets from the old ATA drivers is identical for everything on the same
IDE controller; it basically gives the path to the PCI bus slot where
the IDE controller is connected. So udev has no way to differentiate
between multiple drives connected to a single controller. This is a
change at some point from the previous behavior, which specified the IDE
information as well.
So is this supposed to be a problem only if there is more than one PATA
device?
I never investigated this deeply enough, thanks for your explanation. I
ended up adding code to init scripts to create the links.
You used to get something like:
ENV{ID_PATH}==pci-:00:1f.1-ide-0:0
and now you get:
ENV{ID_PATH}==pci-:00:1f.1
Switching over to libata gives you:
ENV{ID_PATH}==pci-:00:1f.1-scsi-0:0:0:0
which returns everything to working order :)
I guess this means that if one gets some other way to match a drive (by
name? serial number?), it's possible to make a working rule.

Was Linux running since before the time change? I suppose it would at least show the right time if that was the case. If it works, you still need CLOCK_SYSTOHC=yes if you want Linux to change the clock. Linux has no way to know if the time change was done (nor windows), unless the systems are syncing with other clock (NTP), so both of them will boot up and think this local time is the winter time. The systems may still register if they already did the timezone change, so that they know what to do (that was the case with windows 98). I had to boot into MSWindows to check what happens there and the clock was showing the new winter time. After that the Linux clock was also showing the updated winter time. Does this mean that twice a year when the clock changes I need to boot into MSWindows first to allow the time change to take place, or is there a Linux side fix for my dual boot set up? You can write something so that Linux changes the clock, but then be sure Windows is not set to change it.

Because the usual setting is UTC, that is, time with no timezone and/or DST shift - GNU/linux does the math and shows you your local time.

An advantage is that the current atom syntax doesn't need to be changed. - add regex support: this would allow exclusion on .unmask, but the syntax may not be the best, and it must ensure it doesn't break with existing atoms (there are atoms using asterisks and package versions have lots of stops) -- Nuno J.
