i855crt gives very "washed-out", bright colours on external crt

[Jens Nachtigall <nachtigall@web.de>]

Hi,

I have a laptop with an i855 graphic card (Fujitsu Siemens Amilo M 7400) and 
used to use i855crt to enable my external crt (for use with a beamer). This 
worked fine until some time ago I upgraded to etch (from sarge) and since 
then I get a white, "washed-out", external screen. An image says more than 
1000 words:

(82k, take with a camera from the beamer)

This is what it looks like on the lcd (same snapshot)

Searching for a solution I came across this thread, which suggests that also 
some ubuntu and fedora users have the same problem:
"i855crt - White / Saturated External Display" --

Anybody seen this as well? Anybody knowing a solution?

TIA,

Jens
