Then please give him mine: I share package cache and repository meta infos via NFS for several systems that are updated in sync; to prevent them all downloading the same files again and again. There's no need to set up an own package repository for that use case, a changed zypp.conf and an NFS mount is all that's needed. I don't do automatic updates, this would disturb operations too much -- these are workstations where people are logged in for weeks or months, not private home systems that get turned off at night. Instead I do nightly checks and prefetch to-be-updated packages. The nightly check sends an email to a sysadmin. After a quick control if the update must be managed manually (e.g., kernel updates, libc updates, X server updates, and such) I have a command that does the update on all systems. Please note that this is actually a reimplementation of THE standard Debian update check functionality: apticron. apticron is actually better than my solution because it includes package changelogs in the email and thus eases the decision process how important the update is. And apticron is one piece of Debian's update management that I miss sorely on openSUSE. But it should be clear from my description that I actually don't need all packages in the cache: I need the currently installed one and all newer ones, owing to the prefetch situation described above. Not quite incidentally I have a daily cron job that cleans up my package cache exactly for this situation and the process described above. It's written in Perl and uses the CPAN classes RPM::Header::PurePerl to parse version infos, and RPM::VersionSort to compare package versions properly. (These two CPAN modules are not available as SUSE packages, AFAIK, at least zypper search doesn't find them; but I have my own Perl installation anyhow for other reasons.) It deletes all packages from the cache where newer versions are installed. It keeps all versions of uninstalled packages, as one might be in the process to test them before rolling them out on all systems. One could think about keeping packages after an update around for a few days, to be able to revert in case of problems, that would be an easy enhancement. If people are interested, I can post that script on the opensuse list; it's just 90 lines including POD docs. But be aware that it won't run on a standard SUSE system due to the missing Perl modules. Just my 0.05 EUR (inflation adjusted).

[opensuse] My first 'Update' 10.3-11.0 - Won't boot - damn disk-by-id problem - help?
by David C. Rankin 22 Jan '09

22 Jan '09

List, After only doing fresh installs since 8.0, I tried my first 'Update' on a 10.3 box going to 11.0. Looks like the update succeeded, but it left me unable to boot. Grub is installed on the right partition, but after booting 11.0, it gets to the place where it is: waiting on required device /dev/long-string-of-id-stuff-part2 and then bombs. '/' is /dev/sda2, '/home' is /dev/sda3 with swap on sda1. I have tried using the rescue disk and: mount /dev/md1 /mnt mount /dev/md0 /mnt/boot mount /dev/md2 /mnt/home mount -o bind /dev /mnt/dev mount -o bind /proc /mnt/proc mount -o bind /sys /mnt/sys cd /mnt chroot /mnt use Yast boot loader config and save, then it bombs again at the same place, I have also tried editing the grub entry at the first boot screen and changing the disk-by-id string to /dev/sda2. Boot dies at the same place: waiting on required device /dev/sda2 So I'm sort of stumped. I recall a rash of problems with disk-by-id, but I didn't save the solution. I'm committed to make this update work. Can anyone share the fix with me? Thanks! -- David C. Rankin, J.D.,P.E.

You're welcome but really the thanks should mostly go to the people who are working on this at the code level. Even though so far for me the result hasn't been that productive, I really do appreciate the time people put into these things. > YaST should prefer ethernet over wifi if there's a cable connected.

Could it be that because I had previously installed OpenSUSE, the installer saw a swap partition on the disk and used it by default? It is definitely using disk for swap at the moment so something went astray. The ps3vram device might be there (I'm not near the system at the moment). I was looking for /dev/ps3vram so I'll go back and look for /dev/mtdblock0 instead. I was under the impression it didn't make it into the kernel until 2.6.29 so I probably jumped to the wrong conclusion. > BuildService for ppc is up at powerpc.opensuse.org. :) Heh.

If you take two screenshots of a browser window with the address bar visible, in each case with a different url, then of course the image files will be different. That's only logical. Also if you save to a file format that saves the modification date+time in some metadata like EXIF, then your md5sum will be different too. Use GOOD computer science, not computer scientology. :p To compare images, you could use imgcmp: $ imgcmp -f 3111skyline-nemesis.jpg -F 3111skyline-ecstasy.jpg -m rmse 71.544772 71.371629 68.839902 Above zero values means that the images are different. You could also use The Gimp: * load the first image * paste the second image as a the new layer * set layer mode to difference or subtraction. If you get a perfectly pitch black result, then they are identical. Anything else is the difference between the two. In case you see a very dark grey noise, then your images are probably almost identical and the difference can be attributed to a different lossy compression quality. See http://www.flickr.com/photos/25187958@N03/tags/opensuse/ for my results on visually comparing the two screenshots. -- Amedee -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] Auto updater fonts to small to read
by Marc Chamberlin 22 Jan '09

22 Jan '09

I have SuSE11.1 with KDE3.5 installed on my media center where I am using a large 1080i monitor and after hours of hunting around got much of the fonts set so as to be readable from across the room. (NOT an easy task!!!) But a few apps still remain recalcitrant and I dunno how to configure them. One of them is the updater applet and even on a large screen I need a magnifying glass to read it! So how does one, with poor eyesight, configure this thing and change the font sizes it uses? (as an aside, if the developers of KDE and SuSE/Linux ever want to make me a happy camper, please think about consolidating all the font control - sizes, colors schemes, font types... into one app somewhere so we poor users don't have to spend hours tracking it all down! I did find the KDE desktop config and qtconfig, but there must be more font configuration places hidden... I know.... if wishes were horses..... ;-) ) Thanks in advance...

Thank you. I'm a KDE user for years. This question came to me after use recently a openSUSE GNOME Live CD. With KDE, the very first session login the fonts looks to big, so I change the theri size in kcontrol (now systemsettings). But with this GNOME live CD, the fonts of size 10p, looks as the same size that the fonts of size 8p in my KDE installed desktop, os I guess that GNOME was forcing 96 dpi. So I guess GNOME by default force to use 96dpi, and KDE use the dpi of the system by default (but I can change this if I want, but what I need to know is if I should want to change it). -- Xavier Callejas -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] PCI wireless card?
by Simon Roberts 22 Jan '09

22 Jan '09

Hi all, Can anyone recommend a PCI (or USB, I suppose) wireless network card (802.11g) that definitely works, out of the box, in OpenSuSE 11.0 / 11., and is still available to buy1? The various HCLs list a bunch of stuff that's old, and claims I should have no problems with some older devices (prism2-based) I have that simply aren't working :( Many thanks, Simon "You can tell whether a man is clever by his answers.

[opensuse] Firefox 3.0.5 and mplayerplug-in 3.55
by Donald D Henson 22 Jan '09

22 Jan '09

(opensuse 11.1) Is anyone else having problems using mplayerplug-in with Firefox? I've indicated mplayerplug-in in the Firefox applications preferences but when I try to play a video, I get a dialog box asking me if I want to open with Banshee or other... If I go to other, I get pointed to my home folder. (Streaming video works just fine.) Any suggestions appreciated. -- Don Henson

[opensuse] a proprietary dvd don't play with xine, but OK with vlc
by Tamas Sarga 22 Jan '09

22 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I borrowed the Batman Dark Knight dvd. I tried to play it with kaffeine, than xine. It starts to use all of the physical RAM then the swap space, not for caching, but the application. And nothing happened, there isn't player window or anything. I had to kill the app. With xine it is OK. My problem is that I'd like to fill a bug report, but I'm absolutely clueless, what should I write into. I use Kaffeine usually and I've never got such problem with it. In addition I have to get the dvd back tomorrow, so I can't debug it further. If anyone has a clue, then please :) TIA.
