I'm running Arch Linux with Mate Desktop version 1.16.0 on Linux kernel 4.8.13. I have a weird problem. My screen turns black after around 5 or 10 minutes and I can not find out why. Here is my mate configuration:
As you can see, the power-management is completely disabled and set to never go to sleep or turn off the display. And the screensaver is set to 2 hours minimum and also disabled.
I have no idea what else I could check. I went through the whole mate control panel to find any hidden settings. Does anyone have any idea why my screen turns black after approximately 10 minutes idle time?
