I recently installed MATE desktop through
apt, but nothing's showing, like my panels and my desktop. Just the wallpaper.
I can launch applications through the terminal only, and when I try to change the panel layout with MATE Tweak tool, nothing works.
EDIT: Never mind. I'm such an idiot. It didn't occur to me that the display was on my LAPTOP's screen, not my second monitor. My laptop's docked and lid was closed and it didn't switch to my external monitor.
