Please open a bug: https://bugs.freedesktop.org/ Product: DRI, component: DRM/Radeon and attach your xorg log, dmesg output, and a copy of your vbios. To get a copy of 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 Thanks!
