Description andreasfrische+redhat 2010-05-26 18:02:07 EDT
Description of problem:
PC has two GPUs:
01:05.0 Display controller: ATI Technologies Inc RS690 [Radeon X1200 Series]
02:00.0 VGA compatible controller: ATI Technologies Inc RV630 [Radeon HD 2600 Series]
* When running without a xorg.conf, the monitor connected to the discrete RV630 card runs normally . The monitor connected to the RS690 IGP is set to wrong refresh rates and will go into standby eventually
* When runnning with a (generated) xorg.conf the RV630 monitor just blanks(backlight on, all dark) when starting X. A switch back to a VT is possible.

Comment 5 Jérôme Glisse 2010-05-27 04:22:54 EDT
You can't do that, you can only have 1 Xserver per GPU and xinerama is not supported with randr1.2 thus you can't reunite the 2 Xserver to have one desktop. Only thing you can do is 1 desktop on each GPU (then matter is how to switch keyboard/mouse btw the 2 Xserver).
