Dave thanks for leading me in the right direction.
Wow this is much dirtier than I ever dreamed, and in no way do I belittle the
work done by the ltsp-team.
Any one who wants or needs to configure X should spelunk
/opt/ltsp/i386/usr/share/ltsp/screen-session.d
For example X_MODE_0 will not have any effect unless XRANDR_DISABLE is set
true.
The documentation advises XRANDR_MODE_ instead, but that wont have any effect
unless X_VIRTUAL or X_VIRTUAL_AUTO are correctly set and then it sets the
virtual size not the monitor resolution.
Finally even xorg does not play fair: after much looking I get ...
r...@ws09:~# cat /var/run/ltsp-xorg.conf
Section "Screen"
Identifier "Screen0"
SubSection "Display"
Modes "1280x1024"
EndSubSection
EndSection
And still xorg configures 800x600 and Xorg.7.log does not show any great
problem
