problem with resolution

[Roger Chrisman]

SS,

I just now experimented with both

 sudo dpkg-reconfigure -phigh xserver-xorg

and

 sudo dpkg-reconfigure xserver-xorg

to see what they do.

They do both reconfigure xserver-xorg (by auto 
editing /etc/X11/xorg.conf) and I presume somehow flag something so 
that the file will be updated again when you upgrade xserver-xorg in 
future.

The -phigh flag causes dpkg-reconfigure to ask you way fewer questions.

Both with and without that flag, dpkg-reconfigure seems to make a backup 
copy of your current /etc/X11/xorg.conf before writing its new one. 
That is nice, should you decide to revert.

The comment that I quoted below from the top of /etc/X11/xorg.conf is 
still relevant, if you do manually modify /etc/X11/xorg.conf.
