I have bought a new laptop and downloaded the latest LTS version of
Ubuntu. When I tried to install the dual boot for the first time, it
failed, then after adding "nomodeset" to the grub menu I managed to
install the same. But after installation there is no gui brightness
control as well as the brightness button is not working. I tried a lot
of methods to fix this, but none worked. Bellow is my system info:

Title:
No brightness controls and /sys/class/backlight empty after upgrade to
Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter
acpi_osi= is a workaround)
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is a case of "Backlight control does not work, and there are no
entries in /sys/class/backlight" for what lspci reports as "NVIDIA
Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)" where the
kernel parameter acpi_osi= is a workaround. (The workaround is also
recorded on Ask Ubuntu at https://askubuntu.com/questions/1030526
/brightness-on-laptop-msi-gt72vr-in-ubuntu-18-04-with-nvidia-gtx-1060
-mobile-does/1043598#1043598.)
The problem is new for me after upgrade to Bionic, although the cause
might be the corresponding update to the NVIDIA drivers.
I will add attachments following the instructions at
https://wiki.ubuntu.com/Kernel/Debugging/Backlight, though most of
them seem to be uninteresting. If I can provide further information,
please let me know.
