dmesg output
On my muxed hybrid system (Lenovo IdeaPad U455) X works fine with IGD gpu
(RS780M), but screen gets garbled when DIS gpu (RV710) is active. In dmesg
output there are lots of following messages:
[drm:r600_packet3_check] *ERROR* bad START_3D
[drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !
My system is:
Lenovo IdeaPad U455 with RS780M and RV710 gpus.
