I tried to disable color tiling and color tiling 2D as a suggested workaround for a similar issue but it does not seem to help in this case. Please attach your dmesg output and your xorg log with acceleration enabled. Created attachment 99952 [details]
Xorg with NoAccel off

(In reply to comment #6) > 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] > Cape Verde LE [Radeon HD 7730/8730] (prog-if 00 [VGA controller]) 'LE' sounds like a harvested card; we're probably trying to use hardware blocks which didn't pass validation. Bug 60879 has some attempts to address this kind of issue. Okay, I'll keep an eye on that report. Thanks for letting me know.

Also to note, that the catalyst driver works fine on that card. Because I'm still having this problem in 3.15.3, is there *anything* I can try to find out which HW blocks are broken and how to disable them? I have no problem messing with the kernel code on my own but I have only a faint idea where to start. GNOME Shell is quite a pain to use over llvmpipe...

Unfortunately they didn't. The only patch that appears to contain a fix for Cape Verde is the "Fix v2" patch for mesa. I rebuilt mesa 10.1.5 (F20's latest) with the patch applied and installed "mesa-dri-drivers" package - as I understand it the patch doesn't affect anything outside this package, right? Attempt to start X with the patched mesa and acceleration enabled leaves me with black screen and the only way to get any debugging info is over SSH. Obtained dmesg dump and Xorg.log is attached. Created attachment 102575 [details]
dmesg with "Fix v2" applied
Created attachment 102576 [details]
Xorg.log with "Fix v2" applied
my 7730 is working now with modified patch, see: https://bugs.freedesktop.org/show_bug.cgi?id=60879#c84 *** This bug has been marked as a duplicate of bug 60879 *** |
