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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
