Created attachment 19737 [details] [review]
Xorg.0.log

Description of the problem

1. I connect my external monitor at VGA-0 output and configure it with
xrandr --output VGA-0 --mode 1024x768 --below LVDS

2. The command from (1) has no impact until I do a VT switch

3. After the VT switch the VGA-0 display is correctly configured. I just run "xrandr" and the VGA-0 configuration goes lost again. Until I do a new VT switch, VGA-0 displays a portion of LVDS.

Does this still happen with xf86-video-ati 6.12.1?  Also does it help if you specify the crtc?

xrandr --output VGA-0 --crtc 1 --mode 1024x768 --below LVDS

I finally upgraded to 6.12.1 (Ubuntu Jaunty just came out), and sadly it still happens.

Nope, that doesn't help.

This should be fixed in 6.13.2.  Please reopen if it's still an issue.
