Comment 103 for bug 1308105

I still get this in xfce4-settings.4.12.0-3 when I shut off the monitor via its power button, or switch to another pc via a K-V-M switch. I'm unable to resume the display when switching back to my Linux pc or turning the power back on. I have to run 4.10.1-1. For a while I used the 4.11.3-3 fix from Manjaro but that doesn't work now either since last -Syu. I'm running Archlinux 4.3.0-1-ck on an Asus M5A88-M mobo, with on-board Radeon 4250 graphics using the HDMI port. The HDMI is directly connected to an Asus VS247 lcd monitor. The K-V-M only switches the keyboard and mouse from the Linux pc, the other pc's it also switches the VGA as they are connected to the monitor VGA (the monitor default is HDMI so I manually switch the monitor by its selector button to VGA for the VGA pc's). I have to remote into the Linux pc and do a normal reboot in order to get the display to turn on else use the power button on front of the Linux pc :(.
Not sure where to look to troubleshoot. Thank you for your consideration.
