--- Comment #1 from Dieter Nützel Dieter@nuetzel-hh.de --- Hello John,
I see nearly the same with all 3.11-rcX and final plus 3.12-next. Only diffence with dpm=0 I get partially mosaic with bigger videos (1280x720 H.264 and 1920x1080 H.264) from time to time.
But my system is much slower than yours:
poor Duron 1800 ;-) RV730 AGP (4650) Mesa 9.2 and git master 3.11 and 3.12-next
power_dpm_force_performance_level didn't works for me, too.
I am not sure what else to attach.
Maybe your dmesg.log, Xorg.0.log and your vbios.
(as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom
Mine comming, here. (With dual DVI monitor configuration I got something in dmesg) [drm:rv770_dpm_set_power_state] *ERROR* rv770_restrict_performance_levels_before_switch failed
Regards, Dieter
