How do i remove that info and try ( sudo nvidia-xconfig --add-argb-glx-visuals ) as suggested by Mhmrcs .
I think all changes are written to /etc/X11/xorg.conf
So you can try editing that file as root. If you don't know how to do this:
- press Alt-F2
- enter "kdesu konqueror" (without quotations)
- give root password
- navigate konqueror to /etc/X11
- click the file xorg.conf to edit it, look for what you had nvidia-xconfig insert and delete that line
- save the file
- CAVEAT: ALWAYS MAKE A COPY of your old working xorg.conf before tempering with it. If X refuses to start, you can fall back to your old copy (in that case you can use a live-cd to delete xorg.conf and rename your copy to xorg.conf to get your original config back. You don't need a live cd if you can do that in a terminal)
