I have an integrated graphics card in my Ryzen AMD APU that uses 1 GB of the system's memory. I want to disable it in order to use all the RAM. My laptop has a dedicated graphics card, but in the BIOS there are no options to only use the dedicated graphics card. Can I disable my integrated GPU from Ubuntu?
I have already tried to set radeon.modeset=0 amdgpu.runpm=0
on /etc/default/grub
and then recompile GRUB without any success.
Running sudo lshw -c video
I see two graphics cards at the moment:
