[SOLVED] Can't add native resolution (DVI->VGA connection, NVidia)

Hi there!

I can't add my monitor native resolution to xrandr.

With closed-source nvidia drivers I'm stuck at 640x480, with nouveau at 1024x768.

I've tried to follow the wiki:

[Under Nouveau]

Screen 0: minimum 8 x 8, current 1024 x 768, maximum 16384 x 16384
DVI-I-0 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768      60.00*+
   800x600       72.19    60.32    56.25
   640x480       59.94
   512x384       60.00
   400x300       72.19
   320x240       60.05

xrandr --newmode "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync

xrandr --addmode DVI-I-0 1280x1024_60.00
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  33
  Current serial number in output stream:  34

I've followed all instructions on https://wiki.archlinux.org/index.php/NV … r_BadMatch for proprietriary drivers, but no joy. Under both nvidia and nouveau drivers I receive the same error.

Setting things in xorg.conf does nothing. Log reports:

[   940.650] (WW) NVIDIA(0): No valid modes for "CRT-0:1280x1024_60.00"; removing.
  3 [   940.651] (II) NVIDIA(0): Validated MetaModes:

  1 [   940.657] (WW) NVIDIA(0):     maximum image size; cannot compute DPI from CRT-0's EDID.

Thanks in advance for any help!

Edit: I should add that I'm using DVI->VGA dongle between NVidia Quadro 4000 and E178FP Dell monitor.

Solved by editing xorg.conf to this form:
