[Ubuntu-x-swat] [Bug 540112] Re: Can not change LCD brightness on Lenovo Y450 laptop
What is the best way to install the EnableBrightnessControl fix if xorg.conf doesn't exist (a common situation now)? I tried creating xorg.conf as Section Device Identifier Configured Video Device Driver fbdev Option RegistryDwords EnableBrightnessControl=1 EndSection with material copied from xorg.conf.failsafe but that didn't have any effect. -- 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/540112 Title: Can not change LCD brightness on Lenovo Y450 laptop ___ 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

This can be resolved by disabling VT-D in the BIOS too as I just found out. http://www.nvnews.net/vbulletin/showpost.php?p=2259741postcount=46 -- Can not change LCD brightness on Lenovo Y450 laptop https://bugs.launchpad.net/bugs/540112 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. ___ 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

Robert, that completely fixed it! I had been googling off and on for what seems like 6 months without a solution, and, bam, that gives me backlight control as well as automatic dimming based on activity.

No worries, it's not something we can just globally enable for everyone so tricks like that are often needed with the proprietary drivers. ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: Incomplete = Fix Released -- Can not change LCD brightness on Lenovo Y450 laptop https://bugs.launchpad.net/bugs/540112 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. ___ 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
