But does the presentation software only work with pictures and the presenter slides (Power Point) or only for presenter slides or will it display say what is on the screen, such as the Word Editor/Text Editor or Music Player or console?

My CaCko ROM version has ‘Mirror” which I believe is supposed to “mirror” the display on a presentation card. Is this so and if so, is that a USB to VGA or the Sharp CF to VGA?

I’m running Qtopia 1.5.4
Kernel 2.4.20
CaCko Zaurus Qtopia Rom 1.23 for the SL-C3200

As far as I understood, the SiS (USBVGA) presentation app is only for displaying image files on the output.
But if we have the sources, it can probably be modified to mirror the screen as well.

TheCacko "Mirror" program is actually the cfxgamirror program which mirrors the actual screen contents on the CFXGA card (by IODATA).
However, I have never gotten this to work in a stable way. cfxga always crashed my system, no matter if Cacko or pdaXrom. Well, there is a C++ version of cfxgamirror, which runs stable but is not able to crete good output. Only 480x480 with the remaining screen lines cropped and the right side of the screen black (basically the 640x480 rotated by 90 degrees).

Has there been any progress in the last 8 months on this front?  Specifically, has anyone had success mirroring the screen to an external monitor?  I typically make my presentations in LaTex and put them in a .pdf file, using href to link to shell scripts to run movies or show simulations.  I use acroread in full-screen mode to show the .pdf file, although there's no reason not to use qpdf2.  Now, I gather that the refresh rate is too slow for animations or movies, and that's fine for now.  But the screen-mirror option is paramount, since I don't want to change how I make presentations.

Also, has anyone tried the new IO DATA usb-to-vga adaptor?
