Display dimmed down after resume

Hi,

I got myself a Fujitsu-Siemens Lifebook P7120 this weekend. Fantastic laptop. And with Ubuntu Dapper, (almost) everything works. I have yet to make suspend work on a self compiled kernel, but Ubuntu almost manages it.

My problem is that after resume, the screen is totally dimmed down. I have to use Fn+F7 to get light again.Anyone have an explanation for this? Or even better, a solution :D Else, echo 3

Invalid argument". Guess it's unsupported on this machine?

Hope this is the right list for this.

Best regards,
Stian
