I do not recall inputting this line. If I did change it, it must have been as
root as the user doesn't have write access.

I would like a global solution. I am all the users. After loosing login
capabilities for a user on another installation, I set up two on this one.
Sure enough, the one I was working under lost graphic display. So I
immediately created two more. Having a global solution, does have some risk.
If I blow it, I could loose all displays. But the need for this solution is
necessary, the screen is only readable with a magnifying glass at full
resolution.
So where to do I migrate the $HOME configuration?
Is there a way to use /proc/cmdline to get the log on screen set to 1920x108?
