Hi,

I am using git-sources-3.7-rc6 nvidia-drivers 310.19, and a relatively updated mesa/X server/etc
My hardware is a NVidia Quadro NVS160M (G98) on a laptop

I am unable to change my default and native resolution. nvidia-settings report no other resolution, all non-native resolutions mentioned in xorg.conf are rejected
Code:

[ 42262.112] (**) NVIDIA(0): Using HorizSync/VertRefresh ranges from the EDID for display
[ 42262.112] (**) NVIDIA(0):     device LGD (DFP-0) (Using EDID frequencies has been
[ 42262.112] (**) NVIDIA(0):     enabled on all display devices.)
[ 42262.113] (WW) NVIDIA(0): No valid modes for "DFP-0:1600x1200"; removing.
[ 42262.113] (WW) NVIDIA(0): No valid modes for "DFP-0:1280x800"; removing.
[ 42262.113] (WW) NVIDIA(0): No valid modes for "DFP-0:1024x768"; removing.

[ 42262.113] (II) NVIDIA(0): Virtual screen size determined to be 1920 x 1200
[ 42263.180] (--) NVIDIA(0): DPI set to (147, 145); computed from "UseEdidDpi" X config
[ 42263.181] (--) NVIDIA(0):     option

[ 42263.189] (II) NVIDIA(0): Setting mode "DFP-0:1920x1200"

Forcing a lower resolution with xrandr -s 1024x768 makes visible only the upper left part of my desktop.
Wine games (here RA3:Uprising) that try to force a resolutions either fail with messages like
Code:

err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found 1024x768x32 @0! (XRandR 1.2)


or just view the upper left part (like new XCOM)

I do not remember having this issue with older versions of nvidia-drivers, but idk how they were, I've been using nouveau for long time.
Everything works fine with nouveau. The reason I want to use the binariy driver is both the 3D speed (necessary for such an old hardware) and that some games report that some 3D feature is not supported by hardware

Any help?

Did you try disabling EDID?

I believe you can configure ViewPort In/Out and Panning in the "Advanced" options to achieve non-native resolution. This is what the older version (before 300) did automatically under the hood when you choose a lower resolution, now the code in the newer version was rewritten and you still need to do it manually

I've also been running into similar issues.

The latest stable nvidia-drivers are disallowing many video modes that seemed to work fine before.

After Google-ing around, I ran across a forum post that helped me:

http://askubuntu.com/questions/188060/force-video-mode-without-edid-information

I changed up my /etc/X11/xorg.conf.d/20-nvidia.conf as follows (I also could have shoe-horned similar changes into xorg.conf if I was set up that way):

Code:
Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier     "Monitor0"
    VendorName     "KDS"
    ModelName      "Proview"
    HorizSync       30.0 - 98.0
    VertRefresh     50.0 - 160.0

    Modeline "1152x864"    108.00   1152 1228 1356 1600    864  865  868  900 +hsync +vsync
    Option         "DPMS"
EndSection


Section "Screen"
  Identifier     "Screen0"
  Device "Nvidia Graphics"
  Monitor        "Monitor0"
  Option "UseEdid" "False"
  Option "ExactModeTimingsDVI" "True"
  Option "ModeDebug" "True"
  DefaultDepth    24
  SubSection     "Display"
    Depth       24
    Modes      "1152x864"
  EndSubSection
EndSection

Section "Device"
  Identifier "Nvidia Graphics"
  Driver "nvidia"
EndSection


The Option "ModeDebug" "True" change was helpful for listing many more valid modes once I turned off EDID with Option "UseEdid" "False"
