<pre>I have problem with radeon cards on muxless laptop:
01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RS880M [Mobility Radeon HD 4225/4250]
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M]
PRIME works almost OK (glxinfo, glxgears, some opensource games), but in some
applications (more critical are Crusader Kings 2 and Europa Universalis 4) I'm
getting black screen and corrupted cursor, switching to some other window
causes X restart.
Tried different window managers (e.g., kdm, xmonad with xcompmgr), results are
the same.
Running Debina GNU/Linux testing+unstable, Linux kernel 3.11.8, drm 2.4.49,
xserver 1.14.3, radeon 7.2.0, mesa 9.2.2.</pre>
