that only go to 1024x768).
The solution I am currently using is to have a modified xorg.conf
(called projector.Xconf in /etc/X11) that has the projector's native
resolution as its only choice in the Modes line in the "Screen"
section. After I plug in to the projector, I do
startx -- :4 -depth 24 -config projector.Xconf
which starts a second X session at that resolution.
Depending on your software that you plan to use for presentation, you
could also use nvidia's xinerama look-alike "twinview" to set up a
dual-screen xorg.conf, and you could set the external screen to be at
your projector's native resolution. I don't use this because I use
acroread for presentations and acroread gets confused about how big
the screen is when I use twinview (duh). However, YMMV.
In case you aren't familiar with starting up two X sessions at
once... when you terminate the "new" one, you should be bounced back
to the old one. (And you can switch back and forth by Ctrl-Alt-F7 to
get to the first X session, and Ctrl-Atl-wherever, where "wherever"
depends on your system setup.)
