What is interesting though, is that once you set the global environmental setup of DRI_PRIME=1 and then make XORG configuration file including enabled option of TearFree, the system will set your OpenGL display driver and device for the Intel, instead of the Radeon, nonetheless by performance difference - for the better - one can tell there is indeed some extra V-RAM buffer going on in the background, cooperating with Intel. It may suggest that somehow this way the Intel hijacks the OpenGL, but in the end, everything works on enough acceptable level, albeit drivers could be better. On the other hand, are hybrid graphics not supposed to work in such a manner?

People with similar set may also experience tearing of dynamic image with basic Intel HD 620. This is the case of drivers, a known issue. Available solutions discussed HERE, for example. Straight to the point, go manual configuration, forget about the Composer option.

Well, I guess that would need some clearing out, nonetheless what I did, basing off a useful topic found on StackExchange forums, was:

Code: [Select]
sudo nano /etc/environment
where at the bottom I would add:

Code: [Select]
DRI_PRIME=1
Then verify and reboot.

EDIT:

Mark the issue as solved?

Though the drives sure are not perfect.

I have intel 620 and I do not use stock drivers. I use a repo with the latest intel 620 xorg and all the newest mesa and so far my picture quality and performance have gone up ALOT.

Managed to initiate the Radeon R7 M445 for particular programs. Launching the program, I need to type:

Code: [Select]
DRI_PRIME=1 %command%
Any hint on how to make this fix a system default?

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: [Select]
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?
