AE_NOT_FOUND Evaluating _DOD I have arch linux installed on my Dell inspiron 3543, fwts told me about a message in my kernal log about an acpi ae_not_found exception while evaluating _DOD. It seems that this is related to my hdmi port which is not working. I'm using the latest mainline kernel, I have both intel and nvidia geforce 920M and I'm using the closed source driver for Nvidia. So what should I do to fix this problem ?

do a dsdt dump, check if you have a method declared like;


Method (_DOD, 0, NotSerialized) // _DOD: Display Output Devices
{
Return (Package (0x05)
{
0x00010100,
0x00010110,
0x0200,
0x00010210,
0x00010220
})
}


if not, do a bios update, and if you still don't you can try to add it and include it via dsdt override (will mark your kernel as tainted though, which means limited support on forums).
