Xorg Crashed - Why?


Hi all.

I'm running LinuxMint 6 Fluxbox edition on my laptop. After some initial problems I have found it to be very stable. However a few minutes ago Xorg crashed the computer and I had to restart. I should point out that I was running quite a few applications simultaneously (firefox, spotify, gnumeric, several instances of abiword) and downloading 3 fairly large separate files at once.

Anyway here is the log output, can anyone tell me what it means?

Code:
Aug 11 13:43:50 andy-laptop kernel: [17293.749783] Xorg[5116]: segfault at 9618e78d ip b7aaad64 sp bfbce580 error 4 in libdri.so[b7aa7000+8000]
Aug 11 13:44:06 andy-laptop bonobo-activation-server (andy-20362): could not associate with desktop session: Failed to connect to socket /tmp/dbus-1nuefP47ls: Connection refused
Aug 11 13:44:11 andy-laptop kernel: [17326.482437] Xorg[20359]: segfault at deadbeef ip b7a5fd64 sp bff83310 error 5 in libdri.so[b7a5c000+8000]
Thanks in advance - I'm just trying to learn...

Andy

I don't know the actual cause of the problem, but DRI is the direct rendering infrastructure, which is the code that allows X windows to talk to OpenGL (to make use of 3D hardware acceleration).

The crash would have been a fault either in libdri, or more likely in the particular 3D driver that is associated with your graphics card. The subsequent fault lines are just the cascade of errors after the first failure (the desktop failing to talk to X, then libdri trying to use a pointer from memory that was not initialized).

If it occurs repeatedly, consider moving to a more recent version of Mint (either wait for version 7 of the fluxbox variation, or use something like the xfce version).

If it still happens with version 7, it would be useful to submit a bug report (giving details of your hardware). You might want to do this through the Ubuntu bug tracking system, and/or through the Mint one.

Many thanks! I will investigate Mint 7 when I have time.
