Hello.
I'm running Ubuntu 10.10 on a system with an nVidia GeForce 6200 card, using official drivers. I've installed electricsheep from the repos, and while it does run well from the command line, it doesn't work as a screensaver – all I get is a black screen.
On the other hand, it does run smoothly on my laptop, which has an ATi graphics card and is also running Ubuntu 10.10.
How can I get it to run under my main PC?

try changing the graphics
Didn't work – and I tried
yes it does
