Thanks for the explanation. That would make sense if the flickering monitor was
connected to VGA-0 (or I haven't understood you correctly). But the monitor on
VGA-0 does not flicker; it's the DVI-0 port that flickers. My apologies for
being incomplete - I should have been more explicit in my previous comment.

Which component(s) would I need to update to test this new call? I'm still
tracking git for most components, so it's only a matter of time before these
calls show up:
ii libgl1-mesa-dri 7.7.0~git20091129+mesa-7-7-branch[..]
ii xserver-xorg-video-ati 1:6.12.99+git20091127[..]
ii linux-image-2.6.32-rc7 20091113
ii xserver-xorg-core 2:1.6.5-1
> You can disable load detection using xrandr:
> xrandr --output <output> --set "load detection" 0
This appears to have no effect. I can't avoid the flickering by setting load
detection to 0 on DVI-0, but also if I set load detection to 1 on the VGA-0
port, the VGA-0 port does not flicker.
