external monitor/data projector switching
 

Hello,

I am using an emachines M5116 laptop (widexcreen 1280x800), with Suse 9.3 (KDE) and and Intel855 GM video card.

The only thing I have to use Windows XP for is making presentations using a data projector. I would like to be able to do this in Linux.

I have installed and tried the following -

i810switch - the data projector display flickers badly and only shows part of the full screen

i855crt - using the command i855crt on rawpipe I get an almost full screen (without the panel at the bottom) and although there is no flickering, the screen is speckling as though the screen is made up of ants frantically crawling on the spot (I don't know how else to describe it I'm afraid).

Can anyone suggest ways of resolving this?

The relevant bits of my Xorg config file are -
