just spent an hour signing up and trawling through 50+ posts on the
nvidia forums and it seems that the issue was first raised when 8.04 was
still in the BETA test stage and people have been raising ever since!
Since 9.04 Nvidia seem to be convinced that there is a underscan setting
in the Nvidia settings, however this is not true, or if it is then myself
and 20+ others can't find it so it is well hidden!
They suggest custom modelines in xorg.conf but all the ones I try
including my TV's native 1280x768 60Hz or 1360 x 768 60Hz result in a
working xorg.conf (always backup your almost working file prior to
playing around then easy to put back!) that is GNOME fails to start and
I'm 'dumped' into text shell (still with overscan!)
I think I shall make do with my 'untidy' panel (toolbar) fix and hope
Nvidia get around to putting in the button they keep directing people to
in the forums!
I imagine it would be possible to do something with Compiz? Someone on
their forum has 'hacked' (not correct as open source!) one of the zoom
plugins to 'zoom out' beyond 1:1 to bring the edges of the screen into
view! hope this can be included as an update or possibly as defult on
lucid or possibly 10.10 (codenamed merry meerkat and what the bigwigs are
aiming to make 'the perfect 10! Can't wait!). will post on Ubuntu
brainstorming in the hope it will be picked up.
Awaiting response from the person on Compiz forum regards the 'hacked'
plugin if possible will try out for myself (my skills are limited but
will try anything once!) and post back.
