black screen with VLC and mplayer
When trying to play a video, I get a black screen. It’s the same with VLC and mplayer.
alias mplayer='mplayer -vo x11'
Go to Tools -> Preferences -> Video. At the Output, choose “X11 video output (XCB)” from the dropdown list. If it doesn’t work, untick the option “Accelerated video output (Overlay)”.
