Nouveau driver and 3440x1440_80 resolution and ASUS GT1030 Nvidia

Hi All,

Having trouble getting my ACER 34" ED347CKR panel to run at it's maximum resolution of 3440x1440_80. (it supports upto 100hz, but cvt shows 100hz at an out of spec Horiz Freq, so lowered to 80)

It is driven by as ASUS Nvidia GT1030 card.

I thought there was support for this card in the Nouveau driver?

xrandr shows:

HDMI-1 connected 2560x1080+0+0 (normal left inverted right x axis y axis) 795mm x 334mm
   2560x1440     59.95

   640x480       75.00    60.00    59.94  
   720x400       70.08

I tried getting a new timing with cvt and setting a new mode with:

xrandr --newmode "3440x1440_80.00"  571.75  3440 3712 4088 4736  1440 1443 1453 1510 -hsync +vsync
xrandr --addmode HDMI-1 3440x1440_80.00

.. and then I set to that mode and the display goes blank and the monitor shuts down .. obviously does not like it.

xorg log shows that DDC modeline include:

[  1818.570] (II) NOUVEAU(0): Printing DDC gathered Modelines:

.. but confused by that as it does not show a frame rate .. I tried the timing in the 2nd line, but no change.
(EDIT: xrandr shows the 1st line as 60Hz, 2nd line as 100Hz) both don't work ..

Any help appreciated ..

UPDATE:

I tried the first line from the xorg log again this time changing the name of mode to "3440x1440_xorg" and it worked!
Seems it did not like the 3440x1440_60.00 style of name .. go figure

Anyway, now I have a hi res screen ,,, yay
