Now, please answer the following questions:
1) What version of Debian are you running?
2) How do you log in to your computer? If it's by a display manager
(graphical login), which one is it?
3) How do you start the X window system?
4) How have you configured whichever dot files are relevant to #2 and #3?
5) What is the actual problem you are having?
#2 IS CRITICALLY IMPORTANT and I have never yet seen you answer it.
Maybe I missed it somewhere in this incredibly drawn-out and unfocused
thread, but I don't think so.
