When I boot into my fedora RawHide installation I can't run X. I get a bash login prompt and I login, then I type X and it tries to run, might make the screen flicker on my laptop, then it gives me the message No screen detected. This comes after I accidentally left my external monitor plugged into my laptop, and when I unplugged the monitor and went back in I got the same error. I looked at my Xorg.conf file and found that there is a screen their, but it isn't supporting widescreen resolution ( I added 1200x800 support, but nothing changed). Is there any way to reset my Xorg? I definitely tried to use yum (yum reinstall X) but of course, it's not that simple is it?

is there a line in your xorg.conf file under the screen section that has "monitor0" or "monitor1" in it? or do you have more than one screen section in the conf.

No, I have just one screen, and nothing seems to be wrong. X11 tells me that it cannot Detect the screen when I try to run it. I'm not sure why. I am using the ATI radeon drivers, but it just says videocard0 under the device heading. I'm not really sure what to try.

Can you post your entire xorg.conf file I'll see if I can tell whats wrong with it. If the problem is in fact in the xorg.conf file.

Usually when I do that, I log in as root and do "cp -a /etc/X11/xorg.conf.bak /etc/X11/xorg.conf" and viola! But, a guy needs to know what's in his backup file first...

Anyone know the command for ATI cards to reconfigure the xorg.conf automatically from the command line? Something like "aticonfig" or 'aticonfig --initial". Try those.

You've confused your xorg.conf with the external display. I've done it many times. :P The "aticonfig --initial" command should write a new xorg.conf if you run it as root in the console.

Log into root using
then type
It doesn't have to be vi / vim (vim is easier to use) -- you can use ... EMacs.

See if you can find 'monitor0' 'monitor1' or something similar.

Also, see if you can find the line for your driver ... if it's not set to 'vesa', then set it to vesa.

Now try saving (in vi, it is :x).

How are you trying to start X? Usually, you would type 'startx'.

It's alright, I looked at my xorg.conf and notice that the first line was: created by system-display-config. So I typed that in and BAM, back to normal! I guess it was just out of phase with my system or something.
P.S. Do fglrx drivers work with kernal 2.6?
