I’d like to confirm that the Ubuntu 22 kernel installed has GPU support. Any suggestions?

Hello @davec25

For desktop, you can install glmark2-es2-wayland to check the GPU performance.

$ sudo apt install glmark2-es2-wayland
$ glmark2-es2-wayland

Thanks. I’m running headless as I plan to use the GPU for image processing. Can you think of another way? lspci doesn’t report anything and lshw reports 4 CPUs and a 5ith one disabled.

your best bet is for using the mali openCL libraries to make use of the gpu compute power for your applications.

cheers

It definitely looks like the ubuntu 22 image provided doesn’t support the GPU. Am I missing something?
