Thank you for your help, but that didn´t help at all.
I still get the Error:

XRequest.137: BadWindow (invalid Window parameter) 0x4e00004
[stageros-2] process has died [pid 4294, exit code -11].

I tried to remove my xserver-xorg and install it again, but that didn´t  
help either.
The problem is I am new to linux (4weeks+) and can´t really determine from  
where the error is coming.
I mean what is an XRequest.137? Couldn´t find any information on this  
either.
And how come that it worked a week ago and now its jammed?
