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

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)
Comment 2 Tethys 2009-08-27 17:23:41 UTC 
FWIW, system-config-display is useless, and can't see a second video card,
so won't let me configure dual-head.
Comment 3 Tethys 2009-08-27 17:31:13 UTC 
Just for completeness, I also get the same results if I try without
using an xorg.conf at all.
Comment 4 Jérôme Glisse 2009-10-15 14:57:37 UTC 
Do you still have this issue with fedora 12 (you can test livecd from http://alt.fedoraproject.org/pub/alt/nightly-composes/desktop/) ?
Comment 5 Tethys 2009-10-15 15:06:27 UTC 
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.
Comment 6 Jérôme Glisse 2009-10-15 17:05:05 UTC 
Ok so clausing this bug reopen if you experience same issue with radeon hw with fedora 12.
