[vox-tech] using linux laptop with projector...

[Boris Jeremic]

Hello There,

I want to use my laptop (RedHat 9) when I make presentations. I used to 
be able (with old laptop) to change screen resolution from (current 
1600x1200) to whatever will the (outside) projector accept (usually 
800x600 or so...) It used to work (again on old laptop) with CRTL-ALT + 
or - and the resolution would change.

When I use CRTL-ALT + or - now, the actual area of screen changes and 
thus I loose part of screen (it shrinks toward middle part of screen so 
that for example 800x600 is middle quarter of screen only). The big part 
of X window is lost (top menu bar...) and so I cannot use it to show PDF 
presentations, but have to (Yack) reboot to windows and show PDF there 
(I use LaTeX, and foils, slides or beamer classes to make those PDFs...).

Any suggestion on what to do to get this change in resolution, while 
maintaining the screen size (and coverage) would be appreciated.

Thanks, Boris
