Utilizo fedora 28 con dell inspiron 5000. Tiene gráficos híbridos. Debo iniciar sin el adaptador de corriente enchufado. Después de iniciar sesión, puedo enchufar el adaptador de corriente. Antes de apagar debo recordar desconectar el cable de alimentación, de lo contrario Linux se congelará.
No tengo ningún problema en usar fedora solo con batería. Pero cuando se enchufó el adaptador de corriente, surgieron problemas. Por ejemplo, el reproductor de video vlc se congela o el comando lspci falla.
Supongo que el problema está en el soporte vga_switcheroo.
¿Es posible desactivar vga_switcheroo y usar solo la tarjeta integrada?
Este es el estado actual de vgaswitcheroo. La tarjeta de descarte podría asumir valores entre DynOff o DynPwr.
# cat /sys/kernel/debug/vgaswitcheroo/switch
