Comment 27 for bug 259156

Well, even simpler, please do this:

1. switch to a tty (ctrl-alt-f3) and login
2. sudo /etc/init.d/gdm stop
3. pkill X

At this point, you should have no gdm or X processes running. Doublecheck this by running 'ps aux | grep X' and 'ps aux | grep gdm'.

Next, start up X by hand:

4. startx

Possibly this will work fine. Or maybe it will exit back to the command line with or without an error message. Or maybe something else.

If you do see it come back to the command line with some sort of error, run this to capture it:

5. startx > /var/log/startx.log 2>&1

And then attach startx.log to this bug report.

If it does something else, please describe what you experience in as much detail as you can.
