Comment 25 for bug 49827

Yes, read-edid only gets build for i386 and powerpc (from its debian/changelog file).

FYI, the "get-edid | parse-edid" call fails on AMD64 running ubuntu x86, and maybe there's a similar problem in amd64 altogether, why it's deactivated?

$ sudo get-edid | parse-edid
[...]
VBE/DDC service about to be called
        Read EDID

        Performing real mode VBE call
        Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0
        Function supported
        Call failed

The EDID data should not be trusted as the VBE call failed
Error: output block unchanged
parse-edid: IO error reading EDID

Attached is the full output for this command.
