I just shut down my Linux session and the screen went white. I switched to another console and did 'shutdown -r now'. When it came back up, I couldn't get my x session to come back. It says to hit yes or no to try to start up an existing x session. No matter which choice I try, it doesn't do anything. I can switch to another console but when I type startx, I get no joy.
How can I kill this hung x session?
