Hi Wayne-- Currently it's "No Effect". When I bring up my "Administration" => "Additional Drivers" dialog it says the nVidia driver is installed and being used. This is going to sound really strange, but there is no /etc/X11/xorg.conf file. There is a "save" version that I made when backing up the config when I was dealing with the "X won't come up" problem. I removed xorg.conf in hopes it would be re-installed. I just figured it had been since my desktop is up and running. Here's a directory listing of /etc/X11: ethan@rover:X11$ ls -1 app-defaults cursors default-display-manager fonts rgb.txt X xinit xkb xorg.conf.save Xreset Xreset.d Xresources Xsession Xsession.d Xsession.options Xwrapper.config I didn't even know X would come up without an xorg.conf file! --Ethan On Fri, Mar 11, 2011 at 7:34 AM, Wayne Davison
