Nvidia - refresh rate not supported

Hi.

No matter what options in xorg.conf used, I can't set my refresh rate to 75 Hz (I'm sure this it is possible, i.e. on Debian or Windows).
Trying to change that in nvidia-settings ends up with nothing (nvidia-settings -q RefreshRate is saying 60,02 Hz).

Some info from xorg.conf:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "FUS H19-1"
    HorizSync       31.0 - 81.0
    VertRefresh     56.0 - 75.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 9600 GT"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
#Option         "metamodes" "1280x1024_75 +0+0; nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
        Modes      "1280x1024_75"
    EndSubSection
EndSection

Need help.

Re: Nvidia - refresh rate not supported

Have you tried via the graphical 'nvidia-settings'?

Yes, two possible modes there (60 and 75 Hz) to choose, but it doesn't matter what is 'active', because I always get 60 Hz after that.

Re: Nvidia - refresh rate not supported

What's the output of 'xrandr'?

BTW, please use [ code ] tags when pasting code https://bbs.archlinux.org/help.php#bbcode

Re: Nvidia - refresh rate not supported

I have two computers connected to one monitor. One has an ooold integrated Intel card and the other a slightly newer (but still legacy) nvidia dedicated card. When comparing the 'xrandr' outputs I get much better refresh rates (although less resolution modes) from the Intel one. On the one with nvidia I get similar results to yours.

Re: Nvidia - refresh rate not supported

It was also with me on Nvidia 8400GS, I was getting only 50hz instead of 60hz which my Viewsonic VA1912wb LCD monitor supports.

Better switch to nouveau driver, which will get us better refresh rates. After switching to nouveau driver, i get 59.9 refresh rate. Using lower refresh rates tires and hurts the eyes quickly. Now that nouveau drivers with 3d is pretty usable. NVidia closed source drivers will only get reduced refresh rates. Just my 2 cents.

I can't play Unreal Tournament 2004 with nouveau but I can with nvidia-173xx so :-(

Re: Nvidia - refresh rate not supported

I'd suggest this old thread.

Try a modeline entry in xorg.conf, then look at /var/log/Xorg.0.log

Re: Nvidia - refresh rate not supported

I'd suggest this old thread.

Try a modeline entry in xorg.conf, then look at /var/log/Xorg.0.log

When using some options from that thread, resolution jumps to 640x480. In other cases, nothing changes (Xorg refuses to load 1280x1024_75 mode and uses auto-select).
Still not resolved.

Edit:
Changed to nouveau and it seems to work fine... can I belive xrandr or is there any better way to check refresh rate?

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
DVI-I-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
   1280x1024      60.0 +   75.0* 
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   640x480        75.0     60.0  
   720x400        70.1  
DVI-I-2 disconnected (normal left inverted right x axis y axis)

However for some reason I can not set 75 Hz to start automatically, but it's possible to fix easier and not a problem.
