xrandr causing screen flickering on 915GM laptop
Last modified: 2009-09-05 13:51:48 EDT
Description of problem:
I'm seeing reproducible screen flickering on my rawhide laptop with a 915GM intel chip. It happens when gdm starts, when I start any wine app, and when I run 'xrandr' from the terminal.
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)
Version-Release number of selected component (if applicable):
Easiest way to see it is to just run xrandr.
Screen flickering. Seems to cause the background picture to break up and jump all around the screen. It doesn't go black, just does strange things to the image currently displaying.
No wacky flickering.
Let me know if anything else is needed.
Oh, on a slightly offtopic question, I was wondering if I am supposed to be seeing pretty kernel modesetting on this hardware. ( Right now I'm just seeing the text mode plymouth startup )

Chmm, in the very end of the log is this line:
(EE) intel(0): underrun on pipe B!
Might be interesting.
And no, there is no kernel modesetting for intel chips, yet. As soon as it is available, it will be provided for Fedora 10 as update. Should happen soon.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
I have the same.
This is fixed for me in Fedora 11.
