Using Linux 3.13, I also see this bug when returning after a longer idle time. No suspend is involved. And still a "xset dpms for off" call fixes the palette problem. Now I had a look at the HWE kernel of our previous Precise (12.04) based release, where we didn't see this problem with the same HW. The attached diff includes all radeon changes between our working version and the current kernel (~2k lines). The most prominent change is probably the default switch to DPM for CHIP_CAICOS, but that's really a long shot (profile => dpm in /sys/class/drm/card0/device/power_method).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
