I have a problem with Ubuntu 18.04 LTS on my GE66 Raider notebook. This machine runs a i7-10850H and RTX 2070 on a 300Hz 1080p display and supports Optimus.
After a clean install, in gnome settings display, I can see the 300 hz option for refresh rate (300.18) precisely. However this do not seems / feels like 300hz on windows, and this is confirmed by the ufo online test.
I tried every single xrandr
command, reinstalling nvidia drivers (currently running 455), setting the refresh rate in Nvidia X Settings but no results.
Current prime-select
mode is Intel because, since I will use Ubuntu mainly for code development, I would like to exploit the Optimus technology supported in this machine to preserve battery life. This means that I would like to run the GUI on the Intel UHD 630 integrated graphics, while leaving the GPU for demanding tasks.

I tried to reinstall ubuntu, update the nvidia driver and set
prime select nvidia
to drive the display with the gpu. In nvidia-settings it is not possibl to change the display resolution nor refresh rate. Is this expected?
UPDATE 1: This happens also with Ubuntu 20.04.
UPDATE 2:
Ubuntu 20.04 has prime-select on-demand
available but this do not solve the problem.
