Before the Ubuntu 7.04 CD finished loading on my ThinkPad T-60 (with preinstalled Vista Ultimate) the following error message came up:"Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem? <Yes> <No>" I input the command "sudo dpkg-reconfigure xserver-xorg." This started the text-based wizard to reconfigure X. After answering all the questions I was brought back to the input screen with the following message: "xserver-xorg postinst warning: overwriting possibly-customized configuration file; backup in/etc/X11/xorg.conf.20070729111015." I have no idea what to input next. Can anyone assist me? Thanks.
