Eu tenho um computador com duas placas de TV PCI. Um é Compro (Win friendly), outro é Leadtek (Linux friendly). Agora, estou tentando otimizar meu processo de inicialização do Ubuntu e gostaria de desabilitar a detecção do meu cartão Compro porque ele não está funcionando no Linux, não funciona e, mesmo que funcione, eu não me importo.
Eu às vezes uso o Windows, portanto, remover o cartão Compro não é uma opção. Existe alguma maneira de dizer ao Linux "ignorar qualquer hardware colocado lá (slot PCI apropriado)"?
Meu dmesg sobre a detecção de placas de TV é assim:

Eu sei, não verei nenhum benefício de aceleração de desativar essa detecção, mas essas linhas aparecem antes do plymouth splash e eu não gosto disso: \
Se você quiser desabilitar um dispositivo, é possível colocar o seu módulo do kernel na lista negra usando o arquivo /etc/modprobe.d/blacklist .
Se você quiser desabilitar a detecção e ignorar completamente um dispositivo, desative a porta PCI relacionada, geralmente da sua BIOS. Se você quiser que o Linux ignore seu dispositivo habilitado para BIOS, você provavelmente precisará corrigir seu kernel.
