I have been waiting patiently for Grigori Goronzy, the developer of eee-control to release a version of the utility for Karmic Koala (URL http://greg.geekmind.org/eee-control/). However, three weeks since Karmic was released, Grigori has yet to release an update.
Dan Amlund has downloaded the latest version Grigori released for Jaunty Jackalope (0.9.4) and fixed it so that it will install on Karmic Koala. I have installed iton my EeePC 701 and everything seems to be working (your mileage may vary).
To get Dan's version of eee-control which works on Karmic Koala,visit Ubuntu Geek's article at URL http://www.ubuntugeek.com/howto-install-eee-control-in-ubuntu-9-10-karmic.html
