Lenovo: cannot change brightness with kernel 2.6.31-4-generic
Hi Ofir,
If you could also please test the latest upstream kernel available that
would be great. It will allow additional upstream developers to examine
the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .
Once you've tested the upstream kernel, please remove the 'needs-
It's the same for me on a Lenovo Y450 with Intel Mobile 4 graphics, but I can
change the brightness with setpci -s 00:02.0 F4.B=FF where FF is a brightest
mode and 00:02.0 is from lspci | grep VGA.
I found this wokraround here: http://bbs.archlinux.org/viewtopic.php?id=73889
How could I set acpi
Lenovo Y450 with nvidia GeForce GT 130M graphics, not fixed for me

Today I've made an update and I've got the 2.6.31-14-generic kernel now.
The problem is fixed, on Lenovo 3000 N100 it works great now (That means you

change it step-less, but thats ok for me)
Thank you for you good
I've got the same problem with my MacBook 2,1 , I'll attach logs
