Hi all,

Didine: Your tutorial seems to work fine. In the version I looked at though 
there were no mention about the /etc/modprobe.d/sony-laptop.conf file 
(containing the "options sony-laptop speed_stamina=3" line). I also had some 
issues with the xorg.conf.NVIDIA file but it turned out that it was a copy and 
paste error.

I'm currently testing out Karmic Koala (2.6.30 kernel). The default module 
already handles most of the buttons which is nice, but does not contain any 
graphics switching features. When compiling and testing Eva Brucherseifer's 
sony-laptop module I had some issues. At the test loading of the module first 
it seemed to work fine but then the display froze up completely. To fix this I 
decided to install the kernel sources and make a diff between the main kernels 
sony-laptop driver and Eva's. I modified the file but still had a similar 
behaviour. After a restart however I got it working fine. Guess Eva's old 
sony-laptop module might still work fine but just in case I'm supplying a patch 
if anybody else has issues.

Thanks all for the great tips and hints.

//Jari
