[i945] [Hardy] X crash when HorizEdgeDelta is set to "10" (i945)

[Cleber Santz]

After lasted upgrade 2 days ago the X show black screen every time i try find more information but can`t find nothing

I get the "Black Screen" when change application, start java application, play sound or video, etc. There no apparent cause.

I think this is the same problem of bug https://bugs.launchpad.net/ubuntu/+source/icedtea-java7/+bug/199198

I'd suggest submitting the output of dmesg too :)

Ok, here is...

Does it still happen if you disable desktop effects?

[Cleber Santz (clebersantz)]

No, without compiz X dont crash anymore

I have the same problem under KDE4 (desktop effects are enabled, but no compiz i use the KDE4 effects) but i have less crashes. X only crashes when i play a video (using dragonplayer) for the first time after booting. After such a crash the shutdown bootsplash is corrupted.
I doesn't happen all the time, I'm not able to reproduce the bug completely by now.

I guess it is the best to get a backtrace https://wiki.ubuntu.com/DebuggingXorg of the crash.

[eternicode (knexor2)]

lsmod shows that I'm using the i915 module.

The only time X crashes is when I use KDE4 + Compiz, but then only when "Option HorizEdgeDelta" is set to 10 and "Option HorizEdgeScroll" is commented out in the "Synaptics Touchpad" section of my xorg.conf. Commenting HorizEdgeDelta and setting HorizEdgeScroll to 0 works fine.

What happens is I log into my account, all my startup apps load, then compiz loads and X immediately restarts, sending me back to the login screen.

I've attached my xorg.conf, Xorg.0.log and dmesg output will be in subsequent posts.
