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. linux-3.7.0-rc3+ libdrm-2.4.39 xf86-video-ati-6.14.6 mesa-9.0 glu-9.0 xorg-server-1.12.3
