NVIDIA 384.59 4k default

English Hardware
#1

Hi,

I am running Leap 42.2 on an Alienware laptop with a NVIDIA GTX 1080 and the latest Linux driver, 384.59

As soon as the driver was installed it sets the resolution to 4k (3840x2160), but a lot of applications (Citrix Receiver I.E.) and games can’t handle 4k that well yet so I want to set it to 2k (2560x1440).

Now in the Gnome settings I only can choose for 4k. The NVIDIA driver has 4k listed as a normal resolution and all others have (scaled) behind it. When I set it to 2560x1440 and I press Apply everything looks normal and this is basically the resolution I want until all applications I use can handle 4k. But this setting doesn’t get remembered.

If you click Quit in the NVIDIA driver settings it says it will save your settings to .nvidia-settings-rc and this is true. But, your resolution is not saved in this file. So basically when ever I log in it’s back to 4k.

There is no xorg.conf but the NVIDIA settings does create a XF86Config file. X doesn’t listen to anything you put in here, but you can use whatever the driver puts in it in the xorg files in xorg.conf.d/50-screen.conf and 50-monitor.conf and so on.

Everything you put in those files are being set by X, except for the resolution settings. These are ignored. My 50-screen.conf looks like this:

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "CustomEDID" "/home/ricardo/Desktop/Meuk/AlienWare-R4/AUO109B.bin"
    SubSection     "Display"
        Depth       24
        Modes      "3840x2160_60" "2560x1440" "1920x1080"
    EndSubSection
EndSection

What else can I do to force X to go 2k by default?

Hi
The resolution settings are controlled via monitors.xml file down in
~/.config so check this file for the preferred width and height is
being set.

Thanks for your reply.

I edited the file to reflect the resolution I want, but nothing changes. I did a reboot to be sure, the file remains untouched and the resolution is still on 4k.

Hi
Remove the file and login/logout and/or reboot the go into the GNOME System Settings Display and set the resolution and check the file changes.

#5

I removed the .config/monitors.xml file and logged out and back in. The resolution still was 4k, the Gnome system settings Display still only showed 3840x2160 and no new monitors.xml was created. :frowning:

Look at the hover text. I think Gnome doesn’t know there are more resolutions other then 4k. According to the NVIDIA settings, 4k is the only resolution that is not scaled.

I booted to windows I have on an USB drive. It also has 1 resolution, and as for scaled resolutions even less than Linux.

The difference is that on windows all applications seem to listen to the windows scaling settings. Windows puts that on 200% where 1k is 100%

Now in the Tweak panel in Gnome you can set scalling on 2 (the NVIDIA driver does this for you) but a lot of applications on Linux do not listen to it. This makes 4k pretty much suck in Gnome. I’ll just have to wait for applications to update and respect the Gnome scaling settings I guess…
