I recently re-installed Ubuntu on my MSI GP62 laptop. However, I cannot change the brightness. I have tried many things, including booting with acpi_backlight=vendor and similar combinations.
It should be noted that the output of
is empty. Perhaps as a result, xbacklight and other applications do not work. I am also using the Intel drivers/nouveau. I tried various versions of the Nvidia drivers, but they all result in a login loop, similar to this: Ubuntu 16 Stuck in Login Loop after Installing Nvidia 364 Drivers.
Output of lspci -vnn |grep VGA:
00:02.0 VGA compatible controller : Intel Corporation Skylake Integrated Graphics [8086:191b] (rev 06) (prog-if 00 [VGA controller])
I am also using the nomodeset kernel parameter - without it I cannot get to the login screen.
Any help would be greatly appreciated!
