cant get overhead projector to work

bolaoi · 06-20-2012, 09:33 AM

Hello,
I'm using Mint 13 on a Dell Precision laptop.
Everything is working,
except I can't get it to work with an overherad projector.
On the windows partition, there isw no problem connecting to a projector/beamer.
When I use control panel | monitors, I notice only one monitor, and
"detect monitors" does nothing.

I'm not sure how to proceed.

On my Dells, there is a hardware function key for rotating from the laptop screen to a projector to both back to the laptop screen. Does yours have something like that and, if so, what happened when you tried it?

On my laptop, it is Fn-F8.
On Windows 7, there is a menu option "connect to projector".

When I use Fn-F8 on linux mint, nothing happens.

I'm out of clues. The hardware keys have worked for me several distros on those computers (but admittedly not on Mint).

The only idea I have right now it to boot to one or two Live CDs of something other than Mint and seeing whether you can use them to connect to the projector.

It might help if you post the information about the video card (running lspci in a terminal should reveal that) and the make/model of the projector. That information might enable someone else to have a clue.
