Bug Description

Binary package hint: xorg

I've been getting random X crashes in Ubuntu 11.04 the last few days. This occurs both at work and at home, i.e. on a Lenovo T series Thinkpad and on an Acer Aspire 58x-series (if memory serves).

This is the backtrace in the Xorg.log from the most recent one:

I'm using Unity on both computers. The X crashes started about May 3rd or 4th. Maybe a broken update? The two computers have different graphics cards.

I first tried to get technical support at ask-ubuntu (http://askubuntu.com/questions/40250/random-x-crashes-in-ubuntu-11-04), but Jorge Castro asked me to file a bug.

I'm also having random X crashes since update to 11.04.

System is a dell laptop with intel mobile 4 graphic card running e16 (no gnome).

Let me know if I can provide any helpful information.

Same story, different desktops (16bit PacBell and 16bit Lenovo both running Unity 2D as fallback recommended for old machines).

Crashes for me too, on both my Sony Vaio laptop (with an ATI card) and ad my home computer (with nvidia card). Both using the ATI/nvidia drivers, and both running Xubuntu with no special effects or compositioning enabled.

I turned off the same effects than #5 but it still kept crashing. I'm using Ubutu Classic with no effects for 2 days and it haven't crashed since then

Even simpler sequence to reproduce:
Log in to Recovery console session.
cd to directory with git branch
Run "git citool"

I have been experiencing this as well. For me, it was sometimes random, but it always occurred when I loaded up Calibre and tried to click on an ebook.

Taking nsanz.cl's advice, I disabled some effects. Calibre no longer crashes X immediately every time (it used to).

After acquiring full backtrace for my crash I understood, that it is not related to this bug.
#794895 is now open for my case.
