Created attachment 358926 [details] xorg log file Description of problem: I upgraded from F10 to F11. Now I only have one screen, and it's driving me nuts! Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.12.2-14.fc11.x86_64 How reproducible: Every time Steps to Reproduce: 1. Boot to init state 3 2. startx 3. Cringe at the lack of dual head Actual results: Same 1600x1200 image displayed on both monitors Expected results: Dual headed goodness (courtesy of some xrandr magic in my ~/.Xclients) Additional info: I don't use Xinerama. Instead, I use the following lines in ~/.Xclients: xrandr --output VGA-0 --mode 1920x1200 xrandr --output DVI-0 --left-of VGA-0 This has worked fine up until I upgraded. Now it fails. Running the commands manually gives: mrburns:~% xrandr --output VGA-0 --mode 1920x1200 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 (RANDR) Minor opcode of failed request: 21 (RRSetCrtcConfig) Serial number of failed request: 24 Current serial number in output stream: 24 Yet xrandr is aware that the monitor is capable of 1920x1200: mrburns:~% xrandr Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 3520 x 1200 VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1600x1200 60.0*+ 1920x1200 60.0 + 85.0 2048x1200 81.2 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.0 60.0 800x600 75.0 60.3 640x480 75.0 59.9 720x400 70.1 DVI-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 408mm x 306mm 1600x1200 60.0*+ 1280x1024 60.0 1280x960 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 720x400 70.1 My hardware details are at: http://www.smolts.org/client/show/pub_2a97004e-5c74-42f5-9952-9058b621ba90
Created attachment 358927 [details] xorg.conf This is my xorg.conf from F10, which worked perfectly on the same hardware (or at least, it gave me the ability to futz around with xrandr to get a working dual-headed system)
FWIW, system-config-display is useless, and can't see a second video card, so won't let me configure dual-head.
Just for completeness, I also get the same results if I try without using an xorg.conf at all.
Do you still have this issue with fedora 12 (you can test livecd from http://alt.fedoraproject.org/pub/alt/nightly-composes/desktop/) ?
No idea. I couldn't live with only one screen, and this bug was getting no attention, so I had to swap out video cards until I got something that worked. Thus I don't have the same hardware any more, and don't have the problem any more.
Ok so clausing this bug reopen if you experience same issue with radeon hw with fedora 12.
