graphics card in debian

[tim wade <discu@openmbox.net>]

Hello list,

My OS:
$ lsb_release -cd
No LSB modules are available.
Description:	Debian GNU/Linux 12 (bookworm)
Codename:	bookworm


How can I check the graphics card model of my computer and how can I 
test the floating-point computing capability of the graphics card?

Thanks in advance.
