MPlayer fails playing movies. Not properly installed?
 
Hi: I have just installed mplayer with the command
Code:
apt-get install mplayer
Then I tested it with a movie I have in the hard disk. However,
Code:

Can you try as a non-root user?

stf92 06-01-2018 09:33 AM
Unbelievable! As a regular user it plays fine! Thanks a lot. And why this restriction?

root does not have the correct terminal assigned. It cannot start a GUI application.

However I can start X as root if I like. I just type 'startx'. That seems to me kind of an artificial restriction imposed by the developers.

No it's not. StartX is executed by root, but that is the X server. Your DE runs with your credentials. When you log in, you get a graphical terminal assigned. Root does not. It is fairly easy to set an environment variable in your root shell to get a graphical terminal assigned.

You can startx as root, but you can't log in to the gui as root.
