I teraz na sterownikach otwartych (własnościowe z AMD dla wersji 20.04 nie działają) nie da się włączyć zewnętrznej karty Radeon HD 6630M. To znaczy jak się próbuje włączać:
W /etc/default/grub

0:IGD:+:Pwr:0000:00:01.0
1:DIS: :DynOff:0000:02:00.0Jest jakiś sposób, żeby w tej wersji ubuntu 20.04 udało się zmusić zewnętrzną kartę do działania?
