People, I finally found a real workaround. using the official nvidia driver, I installed the package nvidia-bl-dkms from the Mactel PPA (https://launchpad.net/~mactel-support/+archive/ppa)
Now I can control the backlight perfectly. Not even with the noveau driver I could control it with this much precision. Just to remember, I´m using the nVidia Corporation GT218 [GeForce 310M] (rev a2) on a Sony Vaio VPCCW21FX. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/764195 Title: laptop screen blacklight brightness always at 100% (even on battery), can't be lowered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/764195/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
