How do I switch between these 2 cards?

@rilicek then try DRI_PRIME, DRI_PRIME=1 glxinfo | grep “OpenGL renderer”` Did you start the switchrooctl service?

Svyatko · December 28, 2023, 8:14am

To OP - post

inxi -aCGz

ILL OP uses desktop.

rilicek · December 28, 2023, 9:00am

I had to start the service:

systemctl start switcheroo-control.service

How to change the default graphic card?

@rilicek Use switcherooctl to launch your application, or if on GNOME DE, right-click the application icon and select launch with discrete graphics.

Unless you have a BIOS option to switch GPU’s?

Some applications like LibreOffice should automatically use the secondary device as a compute node, or some terminal applications like Alacritty, I use nvtop to observe (both with Nvidia and AMD gpu’s)

rilicek · December 28, 2023, 3:45pm

I haven’t Nvidia. I’ve AMD RX560X
I haven’t option to switch GPU in BIOS.
Is there a similar application to nvtop for AMD?

malcolmlewis · December 28, 2023, 3:50pm

@rilicek nvtop works with AMD… then you can only use for offload.

rilicek · December 28, 2023, 7:52pm

It succeeded.
Is it possible to set RX560 permanently?

@rilicek only by that method. You can however copy or create a desktop file in ~/.local/share/applications and adjust the Exec= part to run any application (or script to launch the application)…

Ok. Thank you
