Public bug reported: Binary package hint: xorg
I'm having a tough time getting the backlight adjustment working on a laptop (Lenovo Y450) using the latest NVIDIA drivers for the G 130M in the machine. The laptop function combination keys register as they should, and things get changed in the system in /proc/acpi/video/VGA/LCD/brightness /sys/class/backlight/acpi_video0/brightness Changing the backlight via the function combination (FN + up/down) works right up until the NVIDIA driver is loaded. I am able to adjust the backlight by dropping to a virtual terminal and using the function combination keys there, but that just stinks as a workaround. I've tried the latest driver versions, including the latest beta, without result.
