Comment 80 for bug 345119

I had a lot of random X crashes (with mouse pointer still movable) like described on this page since installing Jaunty. The system logs never record any messages at the time of the crash (they have messages from before the crash, and messages from after when I restart, but never anything from around the time of the crash). I upgraded to the 2.7.1 drivers and it didn't fix the problem, and may have made it crash more often, maybe every hour on average. Most of the crashes happen while I was scrolling in Firefox (it may be because I am in Firefox most of the time though). After a crash, the only thing I could do was to restart the computer using REISUB. (I don't have SSH server on this computer so I can't try to SSH in or anything.) Visual effects are always set to "Off".

My computer is a Gateway MX6927 with a Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03).

Then I changed the AccelMethod to UXA. It has not crashed since (which is strange since UXA is supposed to be less stable). Now my screen does get messed up pretty often (this didn't happen before). It flickers and sometimes "shakes" horizontally every few minutes. And every once in a while (sometimes every hour, sometimes every few minutes), the screen would look like it got horizontally moved to the left side of my screen, with the left fifth of the screen having been moved off the left side and wrapped around on the right. The mouse pointer is not affected though, and I can still use it if I can figure out the right place to click (e.g. when I hover over where a button is supposed to be, the button would be highlighted, even though it is not displayed in the right place). And after I change the window, or if I just continue using my computer normally for another minute or so, the screen would fix itself.

I figure that this is a huge improvement. Hey, the screen gets messed up every once in a while, but it's kinda cool; and most importantly, it doesn't crash my computer and force me to restart and lose all my work; and the problem corrects itself quickly. I just wanted to tell my story so that maybe someone else has my problem and could try switching to UXA, or otherwise learn from my experiences.
