I'm very confused.
Where does the XF86Config-4 file live? I thought it was in /etc/X11.
I also thought that
dpkg-reconfigure xserver-xfree86 was supposed to create a new XF86Config file.
I did an experiment.
I deleted (saved elsewhere) the XF86Config-4 file and tried to recreate it using
the dpkg-reconfigure command above. It errored out that it couldn't be found. So
I created the file with only # marks and re-ran the reconfigure command. It had
no effect.
WTF?
