Description
Sometimes xrandr --listproviders doesn't show my discrete Radeon GPU When I restart Xorg, Radeon appears in the list.
When Radeon isn't detected, these lines are in Xorg.0.log:
[ 17.911] removing GPU device /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1 /dev/dri/card1 [ 17.911] xf86: remove device 0 /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1
When Radeon is in the list, there aren't any lines with "remove"/"removing"
