Full dmesg that I've got; Kernel was booted with drm.debug=1
I have dual-graphics laptop (AMD Fusion A6 based). Here's the hardware spec:
00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI
BeaverCreek [Radeon HD 6520G]
02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Caicos
[Radeon HD 6400M/7400M Series]
I can boot into console with KMS enabled, but when I start X Windows (twm, so,
not 3D, I believe), I get corrupted screen and the mouse cursor is either
locked or unlocked periodically (about 10 seconds for every state). Xorg.log
shows "EQ overflow" errors.
Graphics stack:
- DRM: radeon module; Kernel v3.6.5;
- Mesa 9.0.1;
- glamor(git)
- xf86-video-ati(git); built with --enable-glamor;
P.S.: With EXA or even without explicit definition of "AccelMethod" the problem
remains the same. It is the same either with xf86-video-ati 7.0.0 (non-git).
Attaching dmesg and xorg log.</pre>
