Comment 5 for bug 173552

Still on Thinkpad R31 blank screen, I tried:
Ctrl-Alt-F2 command line, sudo killall gdm
sudo dpkg-reconfigure xserver-xorg
ran through the setup screens. On completion:

"xserver-xorg postinst warning: error while preparing new Xorg Xserver configuration file in /etc/X11/xorg.conf.dpkg-new; not attempting to update existing configuration"

As in the beginning of the note, there isn't any existing configuration.
Any ideas anyone?
Thanks, Jerry
