Open your Linux terminal and type the `inxi -G` command to list installed GPU on your system. It is simple as that. You need to install inxi using your package manager
@nixCraft with a screenshot like this I’m sure you’ll get more questions about cool-retro-term instead :p
@nixCraft nvidia driver on an AMD card? You may want to fix that, and while you're at it move to Wayland...

@nixCraft Thanks for the tool-tips!

Didn't know about `cool-retro-term` or `inxi`. 💻
With on-board tools, I usually do:

`> lspci -v | grep -i "vga" -A 11`

Sure inxi displays more info about the whole GFX-stack (like renderer or Xorg details)

@nixCraft It doesn't seem to work on Mac OS:
