Nvidia proprietary driver doesn't work (GeForce GT 640)

**suskewiet2** · 05-Aug-2020, 10:51

I did a clean install of opensuse 15.2 today and found the nvidia proprietary drivers from the nvidia repo doesn't work.

I tried both the G04 and the G05 driver, but the result is the same: my screen resolution seems to be very low (images and fonts are extremely large, both in KDE and in KDM greeter). As soon as I remove the nvidia propietary driver, resolution is ok again.

Can someone point me in the right direction how to get the proprietary driver working? Until yesterday I was running opensuse 42.3 with proprietary driver and with the same graphics card without any problem.

For GF116 chip you need G04 driver.

Well I tried both G04 and G05, both with same result.

My desktop looks exactly like this one:

267 on a 1680x1050 screen would only be appropriate if the screen was extremely tiny. Can you try the possible solution proposed in https://forums.opensuse.org/showthre...38#post2952838 ?

I also found this in /var/log/Xorg.0.log:

Code:

[    27.422] (==) NVIDIA(0):
[    27.422] (==) NVIDIA(0): No modes were requested; the default mode "nvidia-auto-select"
[    27.422] (==) NVIDIA(0):     will be used as the requested mode.
[    27.423] (==) NVIDIA(0):
[    27.423] (II) NVIDIA(0): Validated MetaModes:
[    27.423] (II) NVIDIA(0):     "DFP-1:nvidia-auto-select"
[    27.423] (II) NVIDIA(0): Virtual screen size determined to be 1680 x 1050
[    27.430] (--) NVIDIA(0): DPI set to (266, 296); computed from "UseEdidDpi" X config
[    27.430] (--) NVIDIA(0):     option

Maybe the DPI is the problem. How can I set it to a lower value? I tried with uncommenting the monitor section in /etc/X11/xorg.conf.d/50-monitor.conf and adding two options:

Code:

Section "Monitor"
  Identifier "Default Monitor"
#
#  ## If your monitor doesn't support DDC you may override the
#  ## defaults here
#  #HorizSync 28-85
#  #VertRefresh 50-100
#
#  ## Add your mode lines here, use e.g the cvt tool
#

Option "DPI" "96 x 96"
Option "UseEdidDpi" "False"

EndSection

But after reboot xorg.0.log still contains:

Code:

[    27.645] (==) NVIDIA(0): No modes were requested; the default mode "nvidia-auto-select"
[    27.645] (==) NVIDIA(0):     will be used as the requested mode.
[    27.645] (==) NVIDIA(0): 
[    27.645] (II) NVIDIA(0): Validated MetaModes:
[    27.645] (II) NVIDIA(0):     "DFP-1:nvidia-auto-select"
[    27.645] (II) NVIDIA(0): Virtual screen size determined to be 1680 x 1050
[    27.653] (--) NVIDIA(0): DPI set to (266, 296); computed from "UseEdidDpi" X config
[    27.653] (--) NVIDIA(0):     option

PS. I don't have an /etc/X11/xorg.conf file

Please do

Code:

susepaste -n suskewiet2 /var/log/Xorg.0.log

and provide the resulting URL here. If it produces a failure message, goto https://paste.opensuse.org/lists and you'll probably see yours listed anyway. We almost certainly need to see the whole log.

Hi @suskewiet2

If you force the DPI font value to 96 in the Fonts menu of the KDE system configuration (last option of the Fonts menu), does it improve or solve your issue ?
It just worked for me.

Hope it helps.
