Today I upgraded my Gentoo systems to nvidia-drivers-180.41.  I had bad news to report the last two times I upgraded nvidia-drivers in nvidia-drivers-180.37 causing strange segfaults and CTRL-C and CTRL-Z not working after nvidia-driver upgrade and high CPU usage.

Well, since I had bad news before I also want to tell you about the good news. I did not experience any problems yet with nvidia-drivers-180.41. I run Gentoo with kernel 2.6.28-zen4 #1 SMP PREEMPT on x86_64 and tried with Quadro FX3400 and Quadro FX350M. Even tuxonice works on my  Dell Precision M65 with the driver. In the past I sometimes had problems with suspending and some nvidia-driver versions.

Well, not everyone is as lucky as I am. Some cards seem not to be recognized anymore by the driver. You can read about this problem on 180.41 — no more support for 6600?

I’m quite happy to have a new working driver after the last two upgrade attempts.

Edit: Sadly I was wrong in this post. nvidia-drivers-180.41 also causes segfaults as well as 180.44 does. These segfaults occur during heavy CPU/MEM usage. (In my case running 6 instances of mencoder simultaneously on 4 cores). After downgrading again to 180.29 everything returned to normality.

Today, while performing a large world upgrade on my gento x86_64 system, I noticed almost every build segfaulting (internal compiler error…). In the meanwhile I was encoding several videos (xvid) with avidemux. thus I had a somewhat high memory usage. Some of the avidemux processes also segfaulted. I noticed these segfaults also yesterday, but thought something was wrong with my video files. After many segfaults the system then ran completely out of memory and I had to reboot.

Because of my last experience with nvidias drivers (see: CTRL-C and CTRL-Z not working after nvidia-driver upgrade and high CPU usage) the nvidia-driver was my first supective. So I masked off nvidia-drivers-180.37 and downgraded to 180.29 again. Afterwads the segfaults didn’t occur anymore.

NVIDIA should really do better testing with their drivers before releasing.  Errors like this are normally extremely hard to track down, since nobody would suspect the graphics driver to be the reason for this. Well, in this case intuition saved me a lot of time…

Today, when I tried to connect to the icq network (on login.oscar.aol.com) I got the error:

“The client version you are using is too old. Please upgrade at http://pidgin.im/”.

I use pidgin-2.5.2 from gentoo portage tree. Everything newer is masked on x86_64 architecture.

emerge “>net-im/pidgin-2.5.2”

…

!!! All ebuilds that could satisfy “>net-im/pidgin-2.5.2” have been masked.
!!! One of the following masked packages is required to complete your request:
– net-im/pidgin-2.5.5 (masked by: ~amd64 keyword)
– net-im/pidgin-2.5.4-r1 (masked by: ~amd64 keyword)
– net-im/pidgin-2.5.4 (masked by: ~amd64 keyword)
– net-im/pidgin-2.5.3 (masked by: ~amd64 keyword)

Is anyone else experiencing this problem?

Addon:

I just upgraded to pidgin 2.5.5 and icq works again 🙂 . Hopefully everything else works also…

Gentoo x86_64 can do this easily by adding

=net-im/pidgin-2.5.5 **

to their /etc/portage/package.keywords and reemerging pidgin.

Yesterday I ran the usual system upgrades of my gentoo system (emerge –sync;emerge -uND world). After a reboot I noticed that in my gnome-terminal CTRL-C and CTRL-Z didn’t work any more. I also noticed that nautilus was using up one CPU completely.

The first reason I thought of was the kbd upgrade to 1.15. I tried to downgrade to 1.13-r1 again, but this did not solve the problem, but anyways, I’ll stay with 1.13 until the init script problems are solved in a newer ebuild.

After some hours of searching and trying I found the following in my dmesg output:

bluetooth-apple[9380] general protection ip:7f277c8b7e5e sp:7fff8b5fd270
error:0 in libGL.so.180.35[7f277c861000+a4000]

So I tried recompiling the bluetooth applet with no success. Well, it did compile, but the error was still there afterwards.

Afterwards the dmesg output  hinted me to try  downgrading nvidia-drivers from 180.35 to 180.29 , which solved the problem.

Experimenting with my VR920 3D stereo glasses I found a patch to enable stereoscopic support in mplayer (thanks to Stuart Levy). With this patch I can now watch 3D movies on my eyewear under linux. Let me tell you, it’s a really cool experience.

The patch should work at least with nvidia quadro boards, probably with some others. It can also be used with CRT and generic shutter glasses. You can download the patch from here:

mplayer-stereoscopic.patch

Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I modified the mplayer ebuild to include the patch. Download from here:

[download#2]

To use it just copy the mplayer subtree from the portage tree to /usr/local/portage/media-video/mplayer and remove the ebuilds. Copy the new ebuild to that directory and the patch to the “files” directory. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc2_p28058-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY="/usr/local/portage"

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy a new experience in the 3rd dimension.

Addon: Updated modified ebuild for the new version in portage tree:

[download#4]

This blog contains information about GNU (Linux). We are using Gentoo on our Systems and want to share our solutions on mygnu.de. We are Jürgen and Thorsten of main-host.de.

To learn about gnu and linux and the difference have a look at gnu.org.

Perhaps you are also interested in viewing the gnu/linux film:codename_gnu_linux.avi

GNU is an acronym for GNU’s Not Unix. One knowing the difference between GNU and Linux could also say GNL – GNU’s Not Linux 😉

In spite of that we will also use common speech and say Linux when we really mean GNU/Linux.
