Hi,
I'm currently trying to find a way to get F12 or Rawhide to work with
my radeon r770 (4850) based card in a useful way. So far booting them
just freezes my system and using "nomodeset" results in a desktop so
slow i can see the windows being redrawn from top to bottom.
I'm trying all this with F12 and nightly live-cd releases. The system
is actually running F11 right now which works great with this card out
of the box.
My question is does anybody with an r7xx card have similar problems
and/or knows a way to get the driver in post F11 versions to work the
same way it does in F11? At the moment there seems to be no upgrade
path for me with the apparent changes made to the radeon driver.
I filed a bug about this but it would be great if somebody knew a
workaround to at least get the same mileage out of F12/Rawhide that I
get out of F11 (i.e. disable KMS support but still get reasonable
peformance in X).

Could you boot into runlevel 3 on your F11 install log in as root and
create an xorg.conf by running 'Xorg -configure'. Create a live usb with
F12 or Rawhide ( or install F12 to another HD or partition ) and then
copy the xorg.conf.new to /etc/X11/xorg.conf on the live usb and see if
that works?
If it does you should be able to create the xorg.conf file on your F11
installtion save the file in /etc/X11/ and upgrade as a potential
workaround until this issue gets resolved..
