Unable to save a specific configuration with my property graphic driver (Manjaro latest)

Support Graphics & Display

Today ,I installed my 390 old nvidia graphic thanks to nikgnomic, but I didn’t realise at that time the part was missing with that installation will unable to save a specific configuration with my nvidia graphic card.:thinking:

When I typed inxi -G

Graphics:
  Device-1: NVIDIA GF108 [GeForce GT 730] driver: nvidia v: 390.157
  Display: x11 server: X.org v: 1.21.1.21 driver: X: loaded: nvidia
    gpu: nvidia resolution: <missing: xdpyinfo/xrandr> resolution: 1: 1920x1080
  API: EGL v: 1.5 drivers: kms_swrast platforms: gbm
  API: OpenGL v: 4.5 compat-v: 4.6.0 vendor: nvidia mesa v: 390.157
    renderer: GeForce GT 730/PCIe/SSE2
  Info: Tools: api: eglinfo,glxinfo de: xfce4-display-settings
    gpu: nvidia-settings,nvidia-smi x11: xprop

An hour ago I tried to install what it seems missing according to that error message xdpyinfo/xrandr with its xorg “variation”. So, I installed xorg-xdpyinfo and xorg-xrandr through add and remove software but nothing change. Every time I restarted my Pc to check if the latest specific configuration of resolution and light and contrast was saved ,nothing happened, the auto resolution, auto color light/contrast was the result

So, does anyone know how to save a specific resolution, bright and contrast even if it’s with command line? and if it’s possible also which specific packages or libraries I’m missing

thnks in advance

Well, I don’t perhaps I’m the only one with a 390 nvidia driver with the latest kernel and Manjaro. But if there some other person surfing the internet this should help them :backhand_index_pointing_down:

I tried with the Display option in Settings of my Xfce Manjaro (should be similar with or Lxde, Kde,etc). In that option I saved one profile with the resolution (not the one by default) I prefer .And then I install through Add/Remove Software xorg-xrandr (to at least don’t have so many missing packages) I restarted my Pc and at least this resolution isn´t bad

Sadly, the contrast and brightness every time I reset those thing return to the zero value by default. So, if there is no way to change contrast and brightness to a specific number. Perhaps the answer could be a software. I know in other OS there some options like Gammy ,but there is no command line available even with “ArchLinux mode”

Manjaro Wiki - Configure NVIDIA (non-free) settings and load them on Startup - Configure The Resolution/Refresh Rate

  1. Open your terminal and enter the following command:

    sudo nvidia-settings

  2. Change resolution and refresh rate in ‘X Server Display Configuration’ tab.

  3. Hit the ‘Save to X Configuration File’ button and save to /etc/X11/mhwd.d/nvidia.conf

  4. Now enter the following command into the terminal to complete the process:

    sudo mhwd-gpu --setmod nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf

The display Color Correction tab has settings for brightness, contrast and gamma

FYI, gammy is now gummy available in the AUR.
