Boa noite.

Hoje eu estava procurando a quantidade de memoria da minha placa de video no Fedora 29.
Como não encontrei nenhum lugar informando comandos para chegar nesse resultado então fui fazendo alguns testes e cheguei neste resultado:


--->> Obs: ( minha placa de video e uma AMD RX 460 )
Comandos:

$lspci

----> ai vc pega essa primeira sequencia de numeros ( 01:00.0 )
$dmesg | grep 01:00.0

como vcs podem ver na 3 linha, informa que esta 4096M em uso, entre outras informações

espero ter ajudado de alguma forma.

Abraço a todos

Boa tarde,
Segue outro método:

ID_VGA=$(lspci|awk '$2~/VGA/{print $1}')

lspci -v -s ${ID_VGA}

#Filtrando:
