Hi, (Original asked on Phoronix: http://phoronix.com/forums/showthread.php?t=15457) I have two video-cards in my computer.. - 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3300 Graphics - 02:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3450 .. and the following monitors attached: - HD3450 --> LG Studioworks 700S - HD3300 ---> Samsung T200 / BenQ FP547 When I start Xorg with the following.. - Xorg -layout seat1 .. I get an error: "Fatal server error: no screens found" Xorg.0.log: http://pastebin.com/m27abe01a xorg.conf: http://pastebin.com/m1ffd63e7 If I set the HD3450 as first device (by disabling the onboard HD3300 in my BIOS) it works perfectly fine. I've asked this question on the Phoronix forum and this is what someone replied (bridgman): "In your xorg log the 3300 was still the primary device, but the monitor it was trying to light up was on the 3450. I don't know the details, but IIRC the secondary card (3450) needs to be handled differently in order to access the BIOS etc... Looks like the 3300 was primary but the driver was trying to light up the 3450 as if *it* was primary and the driver couldn't find the BIOS image as a result. Not sure what to recommend right now but will investigate a bit." So I thought it would be a good idea to isolate the device by: - Xorg -layout seat1 -isolateDevice PCI:2:0:0 But still no joy :(. However, my Xorg.0.log changes: http://pastebin.com/me473775 Thank you, Martijn -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
