Whenever the screen turns off due to inactivity, it cannot be woken up by moving the mouse or by hitting a key. When I kill the Xorg process via ssh with another computer, the screen then comes to life again and I can log back in. When I remove the graphic card from the computer and use the built in graphic card instead, the bug doesn't occur. So I guess it is related to the radeon driver. Oddly enough, there is no problem waking the screen when I type "xset -display :0.0 dpms force off" in a terminal. Moreover typing gnome- screensaver-command -a in a terminal turns my screen off and after typing this line, the screen can be woken up by moving the mouse or by hitting a key. I'm confused.
