root_tux_linux,

What is the vertical refresh rate range supported by your display?

Maybe it'd work if the names in your Modeline and Modes matched...

That, and nVidia will ignore modelines unless you invoke the emergency manual override.

That truncated log tells us your graphics card can theoretically output that resolution and that the monitor's plugged into the correct port. So we can rule those out...

root_tux_linux,

Put the entire Xorg.0.log onto a pastebin site please.

I'm not quite sure what I'm looking for but I'll know it when I see it.
Its not in your log fragment anyway.

root_tux_linux,

Code:
[    10.619] (**) NVIDIA(0): Using HorizSync/VertRefresh ranges from the EDID for display
[    10.619] (**) NVIDIA(0):     device Ancor Communications Inc ROG PG348Q (DFP-2) (Using
[    10.619] (**) NVIDIA(0):     EDID frequencies has been enabled on all display
[    10.619] (**) NVIDIA(0):     devices.)
[    10.620] (WW) NVIDIA(0): No valid modes for "DFP-2:3440x1440_100.00"; removing.


That fragment says that its still using the EDID data and that the driver cannot validate your modeline, so its not using it.

Doesn't
Code:
Option         "IgnoreEDID" "1"
go in the Section "Device" ?

It may be easier to solve this if you can reproduce this on Gentoo first, or at least an unmangled xorg-server and kernel.

root_tux_linux,

Option "UseEDID" "false" is the manual override you need.

If your display gives out of range, your mode line is setting up a mode it cannot sync to.
I didn't check it by hand. How did you make it.?

-- edit --

The comment above the modeline is correct.

-- Edit some more --
The Asus site says
Digital Signal Frequency : Display port 73~88kHz (H) / 30~100Hz (V)
So yoh are well out of range of 73~88kHz (H)

SOLVED!

It's a gnome bug!
gnome sets the refresh rate always back to 60hz even if your config is working!

https://bugzilla.gnome.org/show_bug.cgi?id=655041

Ty, for your help!


changing refresh rate ---> nvidia-settings ---> select resolution ---> select refresh rate ---> merge xorg.conf
After each reboot you can execute ---> nvidia-settings --assign=CurrentMetaMode="3440x1440_100", if you use gnome!


Code:
 xrandr --current
Screen 0: minimum 8 x 8, current 3440 x 1440, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 connected primary 3440x1440+0+0 (normal left inverted right x axis y axis) 798mm x 335mm
   3440x1440     59.97 + 100.00*   94.99    89.96    84.96    79.98    49.99 
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 disconnected (normal left inverted right x axis y axis)

Hey root_tux_linux, any chance you could share your final xorg.conf? I just bought the same monitor and keep getting an "out of range" error from the monitor when I try the one you posted above (with the added "UseEDID" = "false" option).
