[Kernel-packages] [Bug 1517467] [NEW] Function brightness keys do not change brightness.

2015-11-18 Thread Hao Hu 
Public bug reported:

This is occurring on a Lenovo y510p machine running Ubuntu 15.10. My
machine has a double Nvidia GT750M setup, running the latest Nvidia
tested drivers (352.41)

 I have read that installing the nvidiabl driver might help but I wasn't
able to succeed installing https://github.com/guillaumezin/nvidiabl in
my system.

I have attempted editing GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub to 
"quiet splash acpi_osi=Linux
acpi_backlight=vendor" with no success.

I have also attempted adding Option "RegistryDwords"
"EnableBrightnessControl=1" to my nvidia xorg config file with no
success.

I managed a workaround solution by mapping keyboard shortcuts to the
commands xbacklight -inc 5 and xbacklight -dec 5.
