Seems to be an issue with kernels > 2.6.31. I just installed vanilla kernel 2.6.34-rc4 and used karmic's default configuration. When booting I have the similar messages in dmesg:

There appears NO new dmesg entry when pressing the brightness keys. And it works, I can change the brightness w/o problems. -- luminosity screen on a laptop cannot be set https://bugs.launchpad.net/bugs/566193 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
