I just tried installing 304.60 from https://launchpad.net/~noobslab/+archive/nvidia-quantal on my fresh install of Xubuntu 12.10 amd64 with no xorg.conf. Brightness controls did *not* work, as usual, so I'd say it isn't fixed.
Note that the packages at that PPA are labelled as "304.60-0ubuntu1~precise~xup2", so maybe they're not ideal for quantal, but they do seem to work. I couldn't find any other PPA with quantal packages for 304.60. At least not yet. -- 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/562005 Title: Backlight controls of laptops with NVIDIA NVS and Quadro FX 880M GPUs no longer function while using proprietary drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-certification/+bug/562005/+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
