[Nouveau] [Bug 74164] [NV04] Native monitor resolution missing

--- Comment #13 from Mauro Molinari <mauromol at tiscali.it> ---
I see... so, what can I do now to try to understand why that file is not filled
in by nouveau?

monitor-edid talks about some different ways to get the edid: VBE (through BIOS
interruption 10h), ACPI 2.0, Open Firmware, Kernel mode-setting (which is not
working in our case). Another tool, read-edid
(http://polypux.org/projects/read-edid/) seems to use the i2c interface, but
I've not tried to see if it works.

Looking at the monitor-edid output, it seems like it's using the VBE mode to
correctly get this information, but I have to do a "setsebool mmap_low_allowed
1" previously to make it actually work. Could this be somewhat related to the
fact that nouveau can't get the information?
