Here's what I have:

TV1 connected 800x600+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
   848x480        30.0 +
   640x480        30.0 +
   1024x768       30.0  
   800x600        30.0*    60.3  

> 2. xrandr --addmode S-video 800x600

This ran:
xrandr --addmode TV1 800x600

> 3. xrandr --output S-video --mode 800x600 --crtc 1

This ran after a while, although I initially got a "cannot find crtc
for output":

xrandr --output TV1  --mode 800x600 --crtc 1

xvattr -a XV_CRTC -v 1
Found Xv 2.2
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  132 (XVideo)
  Minor opcode of failed request:  13 ()
  Serial number of failed request:  13
  Current serial number in output stream:  14

This step doesn't work. I hear some sound indicating that the TV is
responding somewhat, but it doesn't seem to work.

I'll keep trying, but if you have additional insights, do let me know.


MSDOS didn't get as bad as it is overnight -- it took over ten years
of careful development.
