Fedora 10 Problem: X is hogging CPU

I installed Fedora 10 onto my system where the "nv" driver does not work with my display card GF 6600LM. The installation ends up being a text-based installation. Nvidia driver is later installed manually. Surprisingly, now the X windows take up the tty1 instead of usual tty7 (ctrl-alt F7).

The problem occurs when I start the system into runlevel 3 in console, then "init 5" to start X. The X process is then hogging the CPU.

The /var/log/message is showing something like below:

localhost /sbin/mingetty[2369]: tty1: invalid character 0x1f in login name

Now I find that mingetty keeps respawning tty1.

Solution:

Comment out everything in /etc/event.d/tty1 and forget about the existence of tty1.
Or find a way to get the X windows started back at tty7 (ctrl-alt F7).
