Same here ASUS G75VW-BBK series with Ubuntu 12.04.1 LTS and NVIDIA driver 304, - with/without grub acpi_osi=Linux acpi_backlight=vendor (not working) - with/without xorg.conf Option “registryDwords” “EnableBrightnessControl=1” (not working) - combination of above not working as well
However, fn F5-F6 works perfectly in Grub Menu, but not longer work once Ubuntu login screen (and desktop) note: xrandr --output LVDS-0 --brightness xx works by manipulating image sent to the screen, but it does not adjust the real backlight because I can feel the back of screen lid is warm workaround: set your desired brightness during grub menu (fn F4-F5 works perfectly), but you can not change it once your are in login screen (and desktop), and this does not survive suspend/wake up as well -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1046088 Title: No Brightness Control on ASUS G75VW Notbook (304.43) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1046088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
