xorg 7.2 or 915 resolution crashing on logout

[Dan Gilliam]

Distro: Gutsy Gibbon, Beta

On a fresh install, once out of about 3 times, either Xorg 7.2 or 915 resolution is crashing on logout (I've seen this in other distros as well, the bug seems to be an intel 915 problem more than anything). This crash freezes the whole system hard, requiring a hard shutdown. I don't know what logs might be helpful, if there are any anyway.

One thing, when it crashes, it simply goes to a screen of garbage (colored blocks), and that's that. Total system lockup. I've seen this in sidux before, as well, and was directed to xorg's bug pages, where it seems to be a 915resolution problem.

I have the same problem, but I do not have 915resolution installed. I am using the "intel" driver in xorg.conf. At times. One time, I saw blocks in various shades of gray, the other times I see those colored blocks. This is also a clean install.

Please have a look at bug #127101, bug #138256, and bug #141063 (and maybe many, many more). Seems to me like this is a xserver-xorg-video-intel rather then a xorg or 915resolution one. At least you, Adam, are affected by the intel bug(s).

I'm not sure if those really apply to my specific case or not. In my case, simply logging out, or doing a restart, or doing a shutdown, will trigger it. I've seen this in several distros (including the latest Suse 10.3, this morning. Sidux is where I noted it first a couple of months ago. it crashes right at the point where the x server cuts out and is dropping back to the console for shutting down, restarting, or restarting the x server. It is sounding like it's the xserver-xorg-intel driver, isn't it? Has anyone already fixed this (I tried looking around and couldn't follow who's done what as far as patches, etc. Any thoughts?

My problem seems so random that I'm not sure exactly how it's triggered and what specifically is doing it. However, I do think that it's the driver doing it. After changing the driver that I am using to i810, I no longer have any problems at all. I guess until it is fixed, I won't be able to use that driver. You could also try changing it to i810 and see if that helps you any. There seems to be a lot of trouble with that intel driver.

I was having the same problem for many weeks and tried everything I could find on the Net. Nothing worked. Finally someone suggested updating the BIOS. This worked.

The laptop was a dual boot to XP, and this never hung. For me it was some kind of Ubuntu interaction with a BIOS bug, which did not happen in XP.
Good luck, this was very frustrating...
