It seems to me that your xorg.conf is very short and incomplete. Please run sudo dpkg-reconfigure xserver-xorg.
If you don't know which option to choose, just press enter to choose the default option.

By the way, please >attach< the files next time in separate files instead of pasting everything in a comment. This makes the bug report a lot more readable. It doesn't matter if you post more comments to place all attachments.

I've got a Shuttle SG31G5 barebone system with "Intel G31 Express (Bearlake-G) + ICH7" (according to the manufacturer).

I also get X crashes, two or three times on an ordinary day. Switching to a virtual console doesn't restore the graphics. However, I can restart the computer blindly by pressing Ctrl+Alt+Del. After some time, I can also see the usplash shutdown logo which displays correctly. So it seems that this is not an non-recoverable error as usplash works correctly.

My xorg.conf is quite the original one, I've just added a few lines to make my 5 button mouse work correctly.

This bug makes working with my computer quite an adventure. I have to save my work every few seconds to be sure not to loose too much. I know that this is an dev release. However, hardy is already in beta stage so this bug should be fixed until release of the final version.

I would be glad to help to debug this further. However, I might need some advice of what to do.

The bug contains enough enough information I think for the developers to decide what's the isse. But I'm not sure that the second bug reported in the comments is the same.

I can confirm the bug ... i have the same randomly
It seems to be caused by fbc (framebuffer compression)

My card is a 945gm.

Here is the diff between two Xorg.log, one when the problem occurs, the other when it doesn't.

Tell me if you need more information as above.
