[gentoo-user] Gnome-Keyring not unlocking with Slim Autologin
Hi all, I'm having an issue with the Slim Login Manager and it's AutoLogin feature. With the AutoLogin flag set to no, when I login, gnome-keyring unlocks itself fine, with Evolution being able to utilise it. However, when the AutoLogin flag is set to yes, Evolution invokes gnome-keyring to ask for the Password. Is there some kind of rule where if you AutoLogin, you require some kind of authentication when it comes to unlocking the keyring? -- Kind Regards, Stephen Griffiths

Thanks for you reply Mark. The way you put it makes sense. I guess the option is whether I would like to have the security risk of having my passwords open without needing any kind of authentication. But that depends on whether I can bypass needing to enter a password on autologin in the first please, or if it's not possible.

Days of rebuilding stuff for python 3.2 after removal of python 3.1. and building kde-4.9.3 Try an emerge -pv =sys-fs/udev-196-r1 and see if that gives any reason why Portage isn't happy with it. ebuild R ~] sys-fs/udev-196-r1 USE=acl gudev hwdb introspection keymap kmod openrc -doc (-selinux) -static-libs 0 kB Since I've been following the threads on eudev, I do not want to be out front on this issue. I put /var/ and /usr on the same partition as / I do have other partitions, such as /usr/local/video1 (etc) But I just put /boot / and swamp for the OS on all the gentoo system I need. So I think I should go back to udev 181 ? I only went to udev 196-r1 to clean up the system (late at night just rebuilding and doing what portage wanted to keep rebuilding everything In summary, since I put /var and /usr on the / partition what my best (mainstream) path for udev and all the issues (flags and other packages) to stay mainstream-stable? I'm not sure I fully understand what my best path forward is... /var is more often than not best kept separate from /, as the filesystem needs for those two are usually quite different. Especially with embedded devices - they can be resource constrained and don't have spare resources to waste on inefficient configs. As long as /usr is on the same partition as / you are safe for the foreseeable future. The reason for this whole / and /usr mess can be summed up in a few words: It's a bootstrap problem. Stuff could be needed at some point in the startup process before the system is in a state to present that very stuff, so one uses bootstrap techniques to make the stuff become available somehow when needed. At this point in time, all this stuff reduces to one simple question: is it located on / or is it somewhere under the /usr hierarchy? There does not seem to be any other factor involved. -- Alan McKinnon alan.mckin...@gmail.com

Re: [Bulk] Re: [gentoo-user] Re: Anyone switched to eudev yet?
Thankfully, I've never had to maintain systems whose disks were small and low performing enough that it actually mattered to separate / from /usr. So you don't understand it much at all. Actually many of lennarts pages such as his security.html are full of wildly incorrect claims and innaccurate assumptions and feature plagiarism leading me to believe he doesn't have much experience outside of coding. Going back in time his claim of pulse audio being good for professional audio was also completely off the mark. Seperating Gnome and pulse can now cause pro audio users on binary distro's major headaches too. I pointed one fellow in the direction of a pro audio on gentoo tutorial rather than deal with some new problems a little after systemd hit Arch. -- ___ 'Write programs that do one thing and do it well.

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. I'm sorry, but I just can't let this one go. The reasons are backwards. The limitation in free space was the original reason [1] why / and /usr were separated. In fact, /usr was supposed to serve the same purpose as /home - it was originally a directory for users. It's only a quirk of history that served to keep most of the binaries in /usr when the home directories were moved elsewhere to /home. Long story short, Unix, too, has its share of old farts that are unwilling to embrace change at anything faster than a glacier's pace. Just ask the Plan 9 folks. [1] http://lists.busybox.net/pipermail/busybox/2010-December/074114.html Well fair enough. This stuff is becoming more myth than fact as less and less people are around to remember how it really went. There may even have been to-ing and fro-ing moving bits around till Ken and Dennis settled on the eventual outcome in that post. Either way, we still agree. A separate /usr is, *for the most part*, a tradition applied without much understanding of the reason (most traditions are exactly like this). Most people do not actually need it. Some people do need it and can clearly state why; I am not in that group. Personally, that post on the busybox thread tends to infuriate me every time I see someone reference it. So, sure. The reason / and /usr were originally split is because their disks on the machine they were evolving this on were insufficient for the original layout. Let's look at that again, reduced: They split / and /usr because unforeseen operational requirements for a given system demanded it. And again, reduced: They did something because unforeseen operational requirements demanded it. This, right there, is the reason for separate / and /usr; operational requirements can place constraints on a system such that the initial configuration is no longer sufficient. It's the same reason you might have a separate /home. Or a separate /home/dad. Or a separate /var/cache. Every now and again, taking a folder and putting it on its own disk is the simplest, quickest and most straightforward way to solve a problem with the resources available. Now, why is /usr special? It's because it contains executable code the system might require while launching. But this is _only_ a problem if the code on /usr is required in order to mount /usr. What if /usr is on a raw disk? No special code needed there. What if /usr is on its own partition? No special code needed there. What if /usr is on hardware raid? No special code needed there. What if /usr is on RAID5 with version 0.9 metadata? No special code needed there. There are numerous circumstances where code on /usr should not be required to mount /usr. And circumstances can and have led to a separate /usr on numerous systems. Some people have set it up as read-only for security purposes. Some people have mounted it over NFS. Some people simply ran out of disk space and put it on a new disk. And, yeah, that can still happen; I've had to pull similar stunts on Windows in VMs (yay, junctions!) which grew larger than anticipated due to software updates. -- :wq

Deal with it using any of a variety of bootstrap techniques #1 is handled by policy, whereby any code the system might require while launching is not in /usr. #2 already has a solution, it's called an init*. Other solutions exist but none are as elegant as a throwaway temporary filesystem in RAM. I should be clear that I do not necessarily support Lennart's solutions, but I do support his perception of the problem (at least partially). We cannot support situations where *launch* code is haphazardly scattered in location X and this must always work for all values of X. We already have a remarkably parallel situation in /boot - in order to boot at all, the code running at that point in time needs to be able to find stuff, and it finds it (by policy) in what we will later call /boot.

But that info might be well out of date, I haven't looked at our jabber server for ages. There's no need to - the techies all gravitated by themselves over to GTalk and Skype, claiming that the cloud services did everything they needed and more, and it was there, and it worked. Our in-house jabber server - not so much. Can't say I blame them. It's true. Thanks Alan, this is just the kind of info I need. It sounds like I would be better off with a cloud solution for collaborative chat. Just out of curiosity: why couldn't you use a Jabber client with Bonjour/Zeroconf support (all or most of them?) within the company (which is what this is for IIUC)? With Zeroconf, the Jabber clients find each other, then you wouldn't need to bother with setting up a server. Or is Zeroconf problematic? I know Pidgin can do Zeroconf on Windows, even if you need to manually install a separate package for it to work. That doesn't really work when one fellow is at his desk in the office, another at home on an ADSL connection and the third is a 3rd party dev based in Los Angeles. That's quite common for me. Zeroconf has it's uses, but it does have a rather narrow scope as to where it can work. I understand that, I just thought that Grant was talking about a purely internal chat solution (like my workplace has) - he did say within a company (though admittedly in retrospect I realize that that doesn't necessarily mean *physically* within the company). Regardless, it isn't clear to me that Grant is talking about something that has to be available from anywhere. While he is apparently gravitating towards a cloud solution for chat, my understanding is that that is because then he doesn't have to manage his own server. All of the other solutions mentioned could be for internal *and* external use. Anyway, I was just curious and thought that if this is purely for internal use than Zeroconf might be a good server-less option for chat. -- Marc Joliet -- People who think they know everything really annoy those of us who know we don't - Bjarne Stroustrup signature.asc Description: PGP signature

The reason I discovered the solution was that I looked through the /var/log/Xorg.0.log file. This file is usually 95+% boring technical detail. Near the top of the log file is a section that says... [??.???] Markers: (--) probed, (**) from config file, (==) default setting, (++) from command line, (!!) notice, (II) informational, (WW) warning, (EE) error, (NI) not implemented, (??) unknown. I suggest viewing the log file with your favourite editor, and doing a case-sensitive search on the 2 strings (EE) and DRI (without the quotes). That was what tipped me off to the fact that... a) there was a problem with DRI b) what file Xorg was looking for that it couldn't find Knowing that info, you can put the appropriate entries into the VIDEO_CARDS variable in make.conf. Intel is a bit weird; it wants both intel and the major driver version. E.g. for my older desktop... VIDEO_CARDS=i915 intel ...and for my newer HTPC machine... VIDEO_CARDS=i965 intel Then re-emerge mesa. If Portage asks you to change some USE flags as part of the process, do so unless it causes problems. Once mesa is rebuilt, run... emerge -pv --newuse --deep world This will give a pretend run. If it looks OK, run it for real... emerge --newuse --deep world Again, portage may suggest changing some flags. I ended up having to rebuild xorg-server and one lib. After that, run revdep-rebuild. And if you're changing the card type, you'll have to make the corresponding changes in the kernel via make menuconfig, rebuild the kernel, and reboot. If you get lost, ask here. Copy the relevant error messages from your Xorg.0.log file to help track down the problem. -- Walter Dnes waltd...@waltdnes.org I don't run desktop environments; I run useful applications

All dvd-slideshow and co. do is to resize images (that's a one liner with imagemagick's convert tool) and then join them to compose a video file, muxing it with the chosen audio tracks. You can easily do that with ffmpeg, mencoder or some similar tool of your choice if the menu-driven program doesn't let you bypass the dvd size limit. A video file is the most universal format you can get, unless you want to relly on the tv native player capabilities to do a slideshow, which would also be just fine since any tv that has an usb port can for sure do slideshows as well. 2012/12/19 Joseph syscon...@gmail.com Is it possible to create slide show (pictures) on USB stick and play on a TV? In the past I've used dvd-slideshow but that is a bit of work. I had to re-size the pictures add background music etc. DVD only holds 4GB USB sticks have larger capacity. -- Joseph -- Jesús Guerrero Botella
