Thread: Resolutions and DPI configurations reset after reboot KDE Plasma

  1. #1

    Default Resolutions and DPI configurations reset after reboot KDE Plasma

    Hi,
    I am using OpenSuse Tumbleweed with KDE Plasma. I have a 4K Monitor laptop and when i try to change the resolution or dpi in system settings all the settings are lost when i reboot the pc. The resolution goes back to 3840x2160 and the dpi goes back to 96. I would like to be able to restart the pc and that the changes to the resolution and dpi are saved. I have been researching and I have been able to notice that in Xorg.0.log there is a part that says:
    Code:
    [ No monitor specified for screen "nvidia". Using to default monitor configuration. ]
    I don't know if that has anything to do with my problem. Please if you can guide me to solve this problem. I leave some of the information I have.

    Xorg.0.log (part of it, won't let me put the entire file)

    Default Re: Resolutions and DPI configurations reset after reboot KDE Plasma

    Large files generally clutter a thread when pasted. They should instead be pastebin'd and the resulting URI pasted here instead. We have the susepaste command to do the pastebinning.

    There are multiple ways to configure DPI and resolution. KDE/Plasma has one of its own in settings that may override global configuration, such as NVidia software typically provides, or interfere with any global configuration that exists. Exactly which method are you using? What DPI and resolution are you attempting to have persist?

    Default Re: Resolutions and DPI configurations reset after reboot KDE Plasma

    Hello,

    This is the /var/log/Xorg.0.log file on pastebin:

    https://pastebin.com/UzVQLmRD

    I am trying to set 3840x2160 with dpi 192 or global scale of 200.
    or 1920x1080 with 96 or global scale of 100.

    First when I try to change the resolution to any other that is not 3840x2160 ( the max resolution ) when I restart the pc the resolution come back to 3840x2160. If I try to set global scale to 200 with 3840x2160 on system settings on KDE Plasma when logout and login the settings works, everything looks the correct size, the dolphin show the correct icons sizes, all app interfaces looks good. But when I restart or shutdown the pc and linux boot again all come back to default. resolution to 3840x2160 and dpi to 96, but the rare thing is that the global scale in the system settings of KDE Plasma is set to 200. So I have to set it to any other than 200 apply the settings and put it back to 200 apply the settings again and logout and login to see the changes.

    Default Re: Resolutions and DPI configurations reset after reboot KDE Plasma

    Code:
    video=eDP-1:1920×1080@60
    shows up in your uploaded Xorg.0.log. I doubt that's valid if it's actually what is present in grub.cfg. It should be video=eDP-1:1920x1080@60, if actually needed, which should only affect vttys, not X.

    Whenever you paste the content from running a command in a terminal here, be sure to include it all within code tags, command with output, to preserve the clarity and meaning inherent in the original output formatting given you.

    Note what follows is suggestive, as I'm neither an Optimus nor an NVidia proprietary drivers user.

    Don't try to use Plasma settings to control displays:
    1. disable KScreen 2 in in Plasma background settings startup
    2. log out of plasma
    3. login on a vtty
    4. remove all content from ~/.cache/
    5. edit ~/.config/plasmashellrc and delete all the [ScreenConnectors] section
    6. return to Plasma and finish by using NVidia settings to configure your displays.

    Hi,
    The video=eDP-1:1920x1080@60 on grub was me trying to set 1920x1080 at the boot but does not work so I removed from the grub options.

    I did all the steps you gave to me but no success, I am having same results. Everything resets on reboot.

    Sometimes settings not persisting is a result of accidental file ownership changes in a home directory after using su or making an errant copy. Have you examined yours to ensure all files and subdirectories, as well as your homedir itself, have correct owner and group?

    Hi,
    Everything seems to be normal in home directory, all says that the owner is my user, the group is varying and permissions is varying, but which folder in home directory or files do I need recheck?

    It's usually easier to fix than to check, as all files that aren't symlinks to other locations should be owned by you. There's no simple way to explain the impact of group, as it's possible to be member of multiple groups, but if you are the only user of your PC, it's safe to have all ordinary files in your home be assigned your default group. The simple fix is:
    Code:
    sudo chown -R me:mygroup /home/me
    where 'me' is your login name and 'mygroup' is your default groupname.

    It's also worth investigating whether correct permissions remain assigned to your homedir and all directories and files it contains. If w is missing for owner anywhere it could be responsible for failure to save settings. Logged in as root or using sudo
    Code:
    # ls -l --group-directories-first /etc/skel
    will show what the file and directory permissions will be when a new user is created, a good guide to what you should see.

    ServerArguments=-nolisten tcp -dpi 192 
    erlangen:~ #

    Hi,

    The sddm.conf
    Code:
    
    [X11]
    ServerArguments=-nolisten tcp -dpi 192
    
    I had that on my sddm.conf
    but this only works on the login screen. I did the permission check and it seems it was correct. I did the sudo chown command to change it anyway and didn't work.

    I made and update of nvidia drivers to 470.129.06 and kernel and something is different:

    1. I still cannot change the screen resolution and restart the pc (it reset back to 3840x2160)
    2. When I set 200 on global scale on system settings ( some software's keep the settings after restart others does not keep the settings, so I have to set 200 again apply it logout and login again )

    I don't understand what is happening, for example:
    The icons on the desktop keep the 200 scale but Dolphin does not keep the settings
    Blender keep 200 scale settings but Davinci Resolve does not keep the settings

    Thank you very much for take some of your time to help!
