I us XF86_S3V and tried the following:
- Use xlock when X is running
- Change to the virtual console X was started from (using startx)
- Press CTRL-C
This killed X, but also changed the first line in /etc/X11/Xserver from
which I had to change back in order to use X again.
1. Why was the server changed to XF86_NONEV?
2. How can I prevent anybody from changing virtual consoles and
killing my X session when I am away and locked it with xlock?
