X crashes

looking at /var/log/Xorg.0.log.old after a crash may tell you what went wrong.

hope it helps

Hello,

I have expecting the same problem (xorg/nvidia randomly freezes whole system so you have got a crash and need to hard-reboot)

ubuntu (im using Gnome and gdm):
Ubuntu 7.10

kernel:
2.6.22-14-generic #1 SMP Sun Oct 14 21:45:15 GMT 2007 x86_64 GNU/Linux

nvidia:
nvidia-glx-new 100.14.19+2.6.22.4-14.10
nvidia-kernel-common 20051028+1ubuntu7

lspci:
VGA compatible controller: nVidia Corporation G70 [GeForce 7800 GS] (rev a2)

I have done fresh install and used the restricted modules for nvidia (as "gnome panel" advised me).
Everything went fine, including working compiz plugin, glxgears etc.
I was really impressed that within 30min I managed to install it from scrach and enjoyed eye candy compiz stuff ;-) but unfortunately troubles have appeared quite fast.

In the Xorg.0.log.old there is no signs of errors (EE) or other useful info or warnings (maybe SetClientVersion means magically something ???)

diff Xorg.0.log Xorg.0.log.old

Kernel loads modules fine:
[ 242.312458] agpgart: Found an AGP 3.0 compliant device at 0000:04:00.0.
[ 242.312495] agpgart: Putting AGP V3 device at 0000:04:00.0 into 8x mode
[ 242.312500] agpgart: Putting AGP V3 device at 0000:05:00.0 into 8x mode

Maybe its hardware error ?? How can I be sure of it ?

Cheers and TIAFAH

Hi !

The culprit here is NVIDIA : the closed driver shipped with Ubuntu has lots of problems.

You may want to install a newer version of the Nvidia driver, see https://help.ubuntu.com/community/NvidiaManual

of course, this procedure has some drawbacks : your driver won't be updated by ubuntu anymore, and in case of a kernel upgrade, you could loose your graphic interface, because the driver installed this way will be installed only for the running kernel

tell me if that helps

That's what I thought, so I went to the free supported driver - I still have the problem

please post here the file /var/log/Xorg.0.log.old after a crash

Oliver,
thanx for pointing me out the right link ;-)

I have done the stuff according to your link (I use to do it before as well).

I have downloaded proper driver for AMD64 architecture (NVIDIA-Linux-x86_64-100.14.19-pkg2.run) compiled it and everything works so far. I am not expecting sudden xorg crashes but I am still testing it (compiz, java, glxgears etc works fine for 1h so far).

Cheers,
Jan
