I recently installed Ubuntu 14.04 alongside Windows 7 on my Asus (i5 core and 8GB Ram).
I experience frequent freezes of my screen. I cannot move the mouse, but I can use the keyboard. When it happens I could always open a command line with Ctrl+Alt+F2 and do sudo service lightdm restart
to restart graphics.
But that of course does not fix the problem and is rather annoying since it happens rather often.
How I can find and fix the underlying issue here?
Greets and thanks in advance
lightdm
. simple switch to other tty, and then switch back toC-A-F7
