gnome session RandR's config (was Bug#444223: xserver-xorg-video-ati: RS480 (radeon express X200G series): display goes to sleep after upgrade to latest unstable/sid)
Hey Gnome guys,
Could any of you help us here? Gnome seems to be doing some RandR
configuration at startup, but given the current state of the driver, the
VGA output status isn't reliable, so Gnome's decision may be wrong. How
could Junichi remove this RandR configuration change on Gnome startup?
Thanks in advance and happy new year,
Brice

gnome session seems to save arbitrary xrandr setups and I'm not sure
how or when it does it. I think there is a file you can delete that
will leave the xserver as configured at start up. Perhaps Brice
knows?
