Description alain williams 2006-02-09 09:01:17 UTC 
I want to use my laptop with a data projector, plug it into the back of the
machine, see my presentation on the laptop screen as the audience view the same
thing from the projector. This used to work, then sometimes did/didn't but
became less & less. I assumed something like incompatability between laptop &
projector.

Recently I could not get it to work and someone suggested that I set the laptop
as dual head ... I then got another desktop displayed by the projector, but
different from the one on the laptop screen. This shows me that there is no
incompatibility. What I want it to have the same desktop & applications
displayed on both - so that the audience can see what I am seeing.

My laptop is running an up to date patched fedora core 4.

I upgraded the laptop to Fedora 5.
It now works as I expect as long as I have the projector plugged in when I boot
the machine.
I also find that it works if I boot with a ubuntu 5.10 live CD.

If you want me to send you any details, ..., please let me know.

I have only tested it with one projector, however it was one that did not work
yesterday (& with a fully patched fedora 4).
