Another person with random x crashes on ubuntu 11.04

[Jonathan Polom]

Binary package hint: xorg

This first started happening today, 18 may 2011 but no update was done. Randomly, completely without warning, my desktop session will end, landing me briefly at a tty, and then back at a gdm login prompt. I'm able to log back in through gdm and use the system but all previous applications are closed as it's a new session. The magnitude of this problem is obvious as any unsaved work in any running programs is immediately lost when the crash occurs.

Seeing the other posts here, I checked my xorg logs and found similar backtraces and ubuntu-bug should have attached those logs.

I don't know what else to contribute at this time.

Ubuntu-bug likely grabbed the running xorg log, not the one containing the actual information about the crash. It's attached here.

[Daryl Hall (ubuntu-daryl)]

Same problem here - only occurring since upgrade to Natty on Dell XPS M1330 with Intel GMA. Seemingly completely random reboot of X, only I'm not dumped to the terminal but back to the X login.

I'm using Gnome rather than Unity. I've attached a log showing the seg fault.

Segmentation fault at address 0xa89c470

[Daryl Hall (ubuntu-daryl)]

I think it was cut off the end of the log for some reason so:

I'd like to add that I too am using regular gnome (ubuntu "classic") rather than unity. Unity doesn't perform well enough on my Thinkpad x100e to justify its use (bloated software -- I'm not impressed). Thankfully the old setup is still available. The Thinkpad X100e has a mobile Radeon card in it but I'm not using the proprietary drivers as the open source ones (default in Ubuntu for supported cards) provide better performance.
