description |
The brightness controls on this laptop with NVS 3100m work while running Nouveau or when using a text mode VT, but not while running X and using proprietary NVIDIA drivers. About 3 weeks ago it was possible to force the nvidia driver to control the backlight by adding [Option "RegistryDwords" "EnableBrightnessControl=1"] to the "Devices" section of xorg.conf . While this allowed the backlight to be controlled, the increments were inconsistent and resulted in a buzzing noise from the LED backlight. Since this did not occur while running nouveau or when switching in text VT, something was wrong.
However, adding this option to xorg.conf no longer works. I believe this is some type of regression. The ideal solution would be to apply the backlight control method used by text VTs to X, because it would work around this regression AND prevent the possibly hardware-damaging electrical issues caused by the proprietary nvidia driver's forced backlight controls (which are not enabled by default).
This bad backlight behaviour has been confirmed on ThinkPad models T510 and W510 via http://www.thinkwiki.org/wiki/Category:T510 , and I mentioned it to a developer on the nvnews.net forums.

The brightness controls of laptops with NVIDIA NVS 3100M or Quadro FX 880M GPUs work while running Nouveau or when using a text mode VT, but not while running X and using proprietary NVIDIA drivers. It is possible to force the NVIDIA driver to control the backlight by adding [Option "RegistryDwords" "EnableBrightnessControl=1"] to the "Devices" section of xorg.conf . While this allows the backlight to be controlled, the increments are inconsistent and often result in a buzzing noise from the LED backlight on Lenovo ThinkPad T510s and W510s. Since this did not occur while running nouveau or when switching in text VT, something is wrong.
This bad backlight behaviour has been confirmed on ThinkPad models T510 and W510 with NVIDIA NVS 3100m and Quadro FX 880M chipsets, respectively, via http://www.thinkwiki.org/wiki/Category:T510
Because this issue is related to NVIDIA's proprietary video driver, this issue can only be solved by them. An NVIDIA developer has said he will investigate the issues, which are discussed on the nvnews.net forums at http://www.nvnews.net/vbulletin/showthread.php?t=145105 and http://www.nvnews.net/vbulletin/showthread.php?t=150069 . For future reference, the latest NVIDIA drivers can be found in the Ubuntu X-Swat X updates PPA: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
