........ Much stuff deleted .....................

I have been on vacation.

I Hope I am not repeating information here, but this has been my
solution to the presentation problem identified earlier.

I have one setting for my "standard" (non-talk) laptop mode of operation, and
another for when I am setting up for a "talk".

I enable the talk mode by starting X using

startx -- -bpp 16

(default is 32 bit planes, my standard mode).

I have a bunch of refresh rates selected in the XFree86Config file for
1024 by 768 in "talk" mode. Then I just cycle thru them using
Ctrl-Alt-Keypad+ until I get one that works.

I have only tried this twice (although I give many talks every year I
am just entering the laptop presentation world), but it worked fine
both times. Maybe it will work for you.

# add these into your "Monitor" section

Modeline "1024x768a"   65    1024 1032 1176 1344   768  771  777  806 -hsync -vsync

Modeline "1024x768c"   85    1024 1032 1152 1360   768  784  787  823

Modeline "1024x768e"  115.5  1024 1056 1248 1440   768  771  781  802 -HSync -VSync

# here is my "Screen" section

        ViewPort    0 0
    Subsection "Display"
        Depth       16
        Modes       "1024x768a"  "1024x768b"  "1024x768c" "1024x768d"  "1024x768e"

Good luck!

As an aside, the best solution I have found so far for giving
"powerpoint" quality presentations is to use pdflatex and ppow4 to
construct good pdf files and than use acroread in full screen mode for
the presentation. I still havent found a way to get good animations
into the presentation using this technique. If somebody has a
suggestion I would like to hear about it.
