Question Fedora 12 second display issues.


Well, I tried installing the ATI driver for my specific card and after I did, I couldn't get a GUI, just console.

So I went and uninstalled the driver but now, my dual screen setup is disabled. I try to reactivate it through the desktop display manager but I get "The selected configuration for displays could not be applied. Could not set the configuration for CRTC64" error.

Anyone know how I can get the display configuration of when I first installed? That seem to work fine for dual displays.

since you can get to a terminal still ... log on as root, go to folder /etc/X11 and see if you see anything that looks like xorg.conf with ".backup_fromATI" attached at the end or anything like that. If so, replace what you have with the backup after backing up xorg.conf file that doesn't work. If you don't have a backup, then rename the one you have and restart - forcing the system to create a new one on restart (as if a new boot).

So, if a backup:

mv xorg.conf xorg.conf.backup.nowork
mv xorg.conf.backup_fromATI xorg.conf

shutdown -r now

No backup:

mv xorg.conf xorg.conf.backup.nowork

shutdown -r now

Let us know what happens . . .

See that's the funny thing. I don't think Fedora 12 uses an xorg.conf file.

I might be mistaken though. I think I read that a couple times looking for a solution on the net.

alright, use my doctored up xorg.conf from one of my fedora boxes below (copy and paste, however you can). Fedora will use an existing xorg.conf if there is one in place (in same folder I mentioned above). Hopefully, you'll be able to get some graphics back.

I'm sorry. I guess I didn't fully explain.

I have a single display (GUI) up and running.

I'm trying to get both displays going again.

The desktop display manager doesn't seem to wanna cooperate and gives me the The selected configuration for displays could not be applied. Could not set the configuration for CRTC64" error.

OK, figured it out.

Apparently, the ATI Driver obliterates some critical files that come with the OS needed for proper operation.

Doing a yum reinstall on the org-x11-*, mesa-* and lib* packages returned the dual screen setup back to normal.
