When I open the laptop lid after closing it while running Xubuntu 18.04LTS, the screen is glitched. The glitch itself is hard to explain. When I move my mouse, the screen gets filled up with the color the mouse is pointing at, but only up to the point where the mouse is vertically.
So far, I found only one fix - In Display settings, change the resolution to something different, then restore the resolution back to its initial state.
What alternatives are there?
