Looking for a Debain 11 image, I came across
    Debian 11 Core, command line only
    Debian 11 Desktop, LXDE desktop, no pre-installed recommended software, supports hardware acceleration

I can not use desktop environment (it will become an network appliance without keyboard, mouse or screen), so I tend to use the command line only image and will install what's required.

What is this hardware acceleration and how would I install it if required.
stupid question? Maybe this is only required for video... which I won't use. We will only ssh into this device.

Thanks
