** Description changed: Using Ubuntu on Sony Vaio laptop with Nvidia 8 vga card: There is no way to control backlight brightness on Sony Vaios with 8-series adapters, e.g. nVidia Corporation GeForce 8400M GS nVidia Corporation GeForce 8600M GT (rev a1) The registers have been found (kudos to mikes!). See these hacked nvclock sources for fixed versions which can set backlight on Sony Vaios: http://stud.matrixcode.de/nvclock_hacked_seek.tgz http://launchpadlibrarian.net/18755253/nvclock_hacked.tgz To install nvclock, download one of the tgz files above (these instructions assume you use seek's version), then: ]$ tar -zxvf nvclock_hacked_seek.tgz ]$ cd nvclock0.8b3a ]$ ./autogen.sh ]$ ./configure ]$ make ]$ sudo make install To test, make sure you are using nVidia's proprietary driver, then: ]$ sudo nvclock -S 100 ]$ sudo nvclock -S 5 ]$ sudo nvclock -S +10 So far mikes' registers have been found to work on: - 8400M GS on VGN SZ650N + 8400M GS on VGN SZ650N, SZ750N 8400M GT on VGN FZ38M, FZ11Z, NR31, AR41E, FZ11S, FZ290 8600M GS on VGN FZ31Z 8600M GT on VGN AR71S Add your model to the list by clicking on the "Update description / tags" link, NOT by asking in a bug comment for someone else to do it. Invoking sonybright.sh with hotkeys will do nothing until the script calls new versions of either SmartDimmer or nvclock properly. I have opened bug #286978 against smartdimmer to encourage support for nVidia 8 series on Sony Vaios. Please feel free to visit that bug and click on the 'me too' link at the top. Dual-adapter models (SZ6 among others) can get backlight control with the Intel adapter using xbacklight, and can get hotkey functionality as per bug #173652.
