Radeon-R7-M445, laptop, hybrid: Intel-HD-620

[MS]

Hello,

I am new to Linux. I was seduced by LinuxLite specifically, switched from Windows10 laptop, manufactured in 2016. I am happy with the choice, as I have been digging Linux topics for a while now. The point is, the laptop has hybrid graphics composed of Intel-HD-620, which is the main display driver, assisted with Radeon-R7-M445 dedicated renderer.

The mentioned renderer is unsupported on Linux. I have checked the AMD website and the only drivers meant for it run under WindowsOS. I have seen some instructions on fixing the problem - link HERE - but perhaps due to my lacking, I was unable to get them go; actually, this:

Code:

DRI_PRIME=1 glxinfo | grep 'OpenGL'

moment locks up the system. Hard to tell, I am sure there is something that can be done.

The system does see the device, below are neofetch and system report fragments. The point is, do you have any idea on fixing it, as it would be nice to make use of the equipment available, though perhaps should I seek paid assistance at some specified comany?
