Nearly identical to bug 14927. Xfdesktop crashes sometimes when I power *on* the monitor. 14927 seems to have been fixed and I haven't had this problem for a while. But, since a recent distribution upgrade, I have noticed this problem a few times. Neither power-manager nor xscreensaver has been able to control the monitor sleep in many years, and I haven't tried it recently, but that is why I have to turn on and off the monitor. AMDGPU.
