What I've already tried without success: * Blindly switching to the console and back. * Calling DISPLAY=:0.0 xrandr --output eDP1 --auto via ssh. * Restarting X via ssh. * Blacklist apple_bl on the kernel cmdline (modprobe.blacklist=apple_bl). * Disabling the radeon backlight on the kernel cmdline (radeon.backlight=0). * Using radeontool to turn the backlight back on after suspend.
