AMD Graphics card not being recognised in ubuntu 20.04.4 LTS

cn flag

when trying to find which graphics card is installed on my ubuntu system I have found that there is no graphics card detected. there is no output from lspci or lshw for example, lspci -nnk | grep -i vga -A3 | grep 'in use' returns nothing

any help is greatly appreciated, thanks

edit: lspci output:

Please add output of `lspci` to your question. "vga" is not always there.

yes it is very strange, especially since I only bought the graphics card is the PC wouldnt boot headless without it, so the graphics card must be working otherwise the system wouldn't boot

The proper command to list all GPUs is

lspci -knn | grep -EA3 'VGA|3D|Display'

VGA is not always there ;-)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
