not my dgpu

And what about when running:

DRI_PRIME=1 glxinfo | grep "OpenGL renderer"

Since is a hybrid intel-AMD, you always have to use DRI_PRIME=1 when want an application to use the dGPU. there are other ways to do that tho, so you don’t always run commands from terminal. For example this AUR package: http://aur.archlinux.org/packages/switcheroo-control

So the dGPU is working.

Should work the same on each DE.

i mean the example program

I don’t understand what you mean by this

Once again… I don’t understand what you mean by that…

you said:

sorry but i mean that the program switchroo-control is gnome only but i use kde so doesnt work

12

Where did you get that from?
switcheroo-control is using D-Bus service to check the availability of dual GPU, is DE (desktop environment) independent …

Run this:

and let us know what comes up.

18

so i have to run dri_prime before every program to get my dgpu working

In principle yes, that is how prime offloading is working, but you can also can edit the desktop files your favorite apps that want them to run with dGPU and have the Exec=DRI_PRIME=1 appended to the default command. See more here: Configure Graphics Cards - Manjaro
In case you want to use reverse prime, you will have to see this AMDGPU - Gentoo Wiki

dumb question but does that apply to vulkan apps
