I tried a few things.
1) Option "ConnectedMonitor" "DFP" freezes the computer when startx and I cannot use CRTL+ALT+BACKSPACE (see 1_XFree86.0.log). I have to reset.
2) Option "IgnoreDisplayDevices" "CRT,TV" freezes the computer when startx and I cannot use CRTL+ALT+BACKSPACE (see 2_XFree86.0.log). I have to reset.
3) If I do not put any of these above options, X starts but hangs when the screen which RH logo comes up (where it is loading all the environment). I CAN use CRTL+ALT+BACKSPACE (see 3_XFree86.0.log).
I hope these log files will help someone figure it out...
Thanks to anyone who can help me on this.
