--- Comment #1 from ka.nick at mail.ru --- Created attachment 88936 --> https://bugs.freedesktop.org/attachment.cgi?id=88936&action=edit dmesg output X11 doesn't work on my dual-graphics AMD laptop with kernels 3.10.X - 3.12.X, on 3.9.X and earlier kernels does. Upon startup lxdm shows a garbage instead of normal picture (but the colors are from the picture), X restarts every few seconds, but kernel itself works fine - I can ssh into the comp or restart using the magic key. Have been trying different combinations: EXA/Glamor, various xorg options with basically the same result: in some cases I can see the normal working mouse over the garbage, in some cases I get "GPU stall" message in dmesg, or EQ overflow in Xorg.0.log... R600_DEBUG=sdsafemath - improves a picture a bit; ColorTiling off - makes things even better - in this case about 70% of the screen are drawn correctly, but at wrong position on the screen; NoAccel on - works as with 3.9.X kernel - windows and lxdm screen - ok, background with errors. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
