MX-21 Multiple video cards and hybrid video (Graphics Switching)

#1 Post by FraterLinux »

I got a DELL Inspiron 14z-5423 with Intel/AMD Radeon hybrid GPU. I have already installed MX-21 AHS 64.
How is it done to switch Intel/AMD GPU on MX-21?

I saw an article:
Graphics Switching
https://support.system76.com/articles/g ... ch-ubuntu/
Is there a utility for managing graphics and power profiles for Intel/AMD?

MX in the future will make a tool for switching hybrid GPU? Is there a way to automatically switch Intel/AMD GPUs? If not, how do I switch manually?

The simplest way I found to switch between intel/amd gpu for a specific program was:
GPU AMD:

Code: Select all

$ DRI_PRIME=1 firefox
GPU Intel:

Code: Select all

$ firefox
By default, when running a program, the intel gpu card is used.
It is equivalent to using:

Code: Select all

$ DRI_PRIME=0 firefox

So it's solved?

What do you get with

Code: Select all

$ DRI_PRIME=1 inxi -G
MXPI = MX Package Installer
QSI = Quick System Info from menu
The MX Test repository is mostly backports; not the same as Debian testing

Well... I think so. For now give me power of choice!

But it will be great if MX develops a tool to change the default GPU for all graphics programs! 😃
