Description Dag Bakke 2007-06-06 05:17:12 UTC 
Setting (not just querying) the dimensions of the graphics with xrandr and latest randr-1.2 branch and latest mesa/drm causes a hang. git bisect points at:


dagb@insp8k2 ~/drm $ (16:10) git bisect bad
4e9d215bdfe72588cbacdb17ab9b60a42a43aefb is first bad commit

I have no secondary monitor attached. I use the built-in panel of my Dell Inspiron 8200.

See 11169 for why I need to use xrandr and 3483 for why I'd like to be able to run without vblank interrupts.
Comment 2 Dag Bakke 2009-10-16 15:01:37 UTC 
No longer a problem. I have new hardware, and I bet the bug is fixed ages ago.
