Thanks for the information, I'll try that! I just found something new, that's very odd:
* If I connect a second monitor via VGA, then fullscreen mode works on both my laptop's monitor, as well as on the second monitor without any problems * If I connect a second monitor via HDMI, then fullscreen mode works only on the second monitor * If I don't connect a second monitor, fullscreen mode does not work correctly * Fullscreen terminals from dom0 work correctly, no matter the setup I'm using the following commands to activate the second monitor for VGA: xrandr --output DP2 --mode 1680x1050_60.00 --above eDP1 The following for HDMI: xrandr --output HDMI1 --auto --above eDP1 To deactivate multiple desktops: xrandr --output HDMI1 --off xrandr --output DP2 --off On 09/24/2017 12:24 PM, yuraei...@gmail.com wrote: > On Sunday, September 24, 2017 at 8:52:32 AM UTC, Michael Strasser wrote: >> Hi! >> >> I've been experiencing some strange issues recently, which I can't >> really pin down on anything in particular. >> >> * I've been getting a frozen screen after random periods of time when >> I've been using two different monitors.
