Bug Description

Binary package hint: xserver-xorg-video-intel

Karmic UNR
Version 2:2.8.0-0ubuntu2

I'm on an eeepc 701 with a 915GM. Every time the cursor flickers or I hover over something in the UNR menu that uses clutter, the screen flickers, showing what seems to be some sort of buffer dump.

I'm marking this as a duplicate of bug 412492. Could you test the kernel linked to in comment #6 of that bug report and check if it removes the flickering? If it doesn't, please unduplicate this report.

The complaints in that bug report are identical to what i'm seeing, but the fix is for amd64. I have a 32 bit processor, so the fix won't work for me. Perhaps Leann Ogasawara can shed some light on the situation. I'm not sure if the bug is still a duplicate.

It's still very likely a duplicate. The fix (i.e. the change in the source code) is independent of the architecture [1], but you're right that the test kernel is only built for amd64 and I didn't see that before. The fix will probably be incorporated into the ubuntu kernel soon. Bug 412492 will then be closed as "Fix Released" and you should be able to verify that the new kernel also fixes it for you. In the unlikely event that it doesn't, report it here and unduplicate this bug report.

[1]: The fix is to increase a timeout from 3 ms to 5 ms. https://bugs.freedesktop.org/attachment.cgi?id=28751
