This happened just a few days ago and I've been making do but it has really started to bother me.
When I click F12 on startup and select my Ubuntu it loads fine and I sign in but once I'm signed in for some reason I cannot see any toolbars, for instance the 'tray' with the time and battery left, etc nor can I see the slide bar on the right that has your favorites, nor can I resize any windows?
I can navigate through things using the terminal because I know how to but I can't even close windows, and they all stack up on the top left corner of the screen and since I cannot close or move these windows I am having a hard time.
Maybe I pressed some shortcut to like, lock my windows? or something any help would be great
