[mythtv-users] Help with Modelines

[Mercury Morris]

Instead of continuing with searches for Modeline information, I
decided to try changing the "Modes" line in the "Screen" section of
xorg.conf.  The line was

  Modes "800x600" "640x480"

I changed it to

  Modes "640x480"

and even MORE of the picture was shifted off to the right of the TV screen.

That made it pretty clear that I had gone in the wrong direction, so I tried

  Modes "1024x768"

and the picture is now completely whole.  Nothing is shifted off, right or left.

I didn't think that "1024x768" was available, but the X log file shows
that it is.
Here's part of the log:

I use two options on the startx command and capture the X log
separately from the built-in logging facility.  They are -logverbose 5
and -verbose 5, as in

  startx -- :2 vt9 -logverbose 5 -verbose 5 > startx.txt 2>&1

This change worked for me - the picture is now completely whole - and
the best part is that I didn't have to re-enter the dark world of the
Modeline.
