É homologado para Ubuntu.
Tem até atualização recente de BIOS.
Dell tem bom suporte.

Será que é a Bios??? Vou tentar atualizar, acho meio complicado fazer upgrade da Bios, mas vou tentar.

Talvez seja isso mesmo, aviso depois

Observação:
-Faça cópia de seu "BIOS" atual para arquivo.
Suponho que o software de atualização permite isso.
-Verifique no manual de serviço se por acaso a placa tem 2 BIOS.
Se tiver, é uma "mão na roda".

"Eu uso teclado e mouse usb no note".
Muitos dispositivos de entrada USBs no notebook.
Linux Mint costuma se confundir.
O que mostra o comando?
sudo lshw -c input

Instale:
hardinfo
Abra hardinfo.
O que mostra em "Input Devices"? (vide figura).

Não teve jeito, atualizei o bios para versão A12, e nada. Vou comprar uma webcam, acho que a minha bugou mesmo. Obrigado pela ajuda de qualquer forma. Aprendi muita coisa.
