[Nouveau] custom edid mode 1920x1080 hsync out of range
Hi,
I think this is a bug or what.
My Monitor and video card combination does not support DDC1/2 transfers.
Due to this no EDID information is read and xorg has a limited vesa mode
options. So I cannot use my monitor at Full-HD resolution.
[CODE]
root at Omkara:~# get-edid -b 0 |parse-edid

This is read-edid version 3.0.1. Prepare for some fun.

Bus 0 doesn't really have an EDID...

I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern

[/CODE]
But I created a custom EDID firmware using the one in the Linux kernel
Documentaion/EDID/1920/1080.S, modified it and installed in
/lib/modules/edid/1920x1080.bin
My /etc/X11/xorg.conf.d/files are populated with enough modelines.
But xorg reject them as being hsync out of range.

[/LOG]
But the code in ~/.xprofile does the job of restoring the FHD, but I have
to set a higher resolution, ie 1984x1080, then reset to 1080p native
resolution of the monitor.
This workaound resolves some hiccups of nouveau.

HDMI-1 --mode "1920x1080" --pos 1920x0
[/CODE]
If xrandr can set a native resolution on my monitor, then why does
xorg/nouveau not do its job properly.
I will be testing on nvidia later since nvidia drivers could not set FHD
at all .
