저는 dell inspiron 5000과 함께 fedora 28을 사용합니다. 하이브리드 그래픽이 탑재되어 있습니다. 전원 어댑터를 연결하지 않은 채 부팅해야 합니다. 로그인한 후 전원 어댑터를 연결할 수 있습니다. 종료하기 전에 전원 케이블을 분리하는 것을 기억해야 합니다. 그렇지 않으면 Linux가 정지됩니다.
배터리만으로 페도라를 사용하는데는 문제가 없습니다. 그러나 전원 어댑터를 연결하면 문제가 발생했습니다. 예를 들어 vlc 비디오 플레이어가 정지되거나 lspci 명령이 실패합니다.
문제는 vga_switcheroo 지원에 있다고 가정합니다.
vga_switcheroo를 비활성화하고 통합 카드만 사용할 수 있습니까?
vgaswitcheroo의 현재 상황입니다. 디스크 카드는 DynOff 또는 DynPwr 사이의 값을 가정할 수 있습니다.
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0
이것은 커널 오류를 보여주는 dmesg에서 추출한 것입니다.
