I changed the package selection to xserver-xorg-input-keyboard.

[Timo Aaltonen (tjaalton)]

not a driver bug, and -keyboard isn't used anymore anyway.

Same to me on Fujitsu Siemens M9400

Please try upgrade kernel to http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/
If it fix the problem, please make it dupe of #406515

I am a nubbie and need some help I just installed kubuntu 10.04 on a thinkpad R40. After the install I had two problems
1) Screen is so dark I have a hard time seeing what I am doing. Is there a fix or easy way to adjust the brightness?
2) The default screen size made the fonts so small that it took me 30 min to locate and adjust the screen size
If I could see what I was doing it would be nice.
how do I change the brightness?

@Esteban Dido : you might be facing the brightness issue as described in bug #581834

[bhuvi (bhuvanesh)]

@Esteban Dido : try changing the brightness using the brightness applet.you can add it to the panel by,
right clicking the panel and select add applet and select brightness applet from the list of applets
