Settings won't launch(gnome-control-center)

As the title states I can’t get settings to launch. This is what I get from the terminal.

kinsman@fxdesktop:~$ gnome-control-center

(gnome-control-center:6267): GLib-GIO-ERROR **: 12:36:36.451: Settings schema ‘com.system76.hidpi’ is not installed
Trace/breakpoint trap (core dumped)
kinsman@fxdesktop:~ sudo gnome-control-center [sudo] password for kinsman: ** ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid) Aborted kinsman@fxdesktop:~

I’ve tried removing gnome-control-center and reinstalling it but I get the same errors. After reboot display background and lock screen are gone, I assume because of the gnome-control-center remove and reinstall. Thanks in advance to anyone that could help or has ideas.

Is this a system76 laptop?

It would be useful to know what OS, is it up to date, any particular tweaking you did.

If you removed gnome-control-center you might have to reinstall the gnome metapackage or the OS’ metapackage.

Yes, the problem with removing the package to reinstall it is that you’re also uninstalling everything that depends on that package. Reinstalling the package does not bring back it’s dependents.

This is a Fx 6300 based desktop I built myself a few years ago. I’m running Ubuntu 19.04 and noticed the settings issue after trying to install GLXOSD with no success.

Also how to I put the terminal commands in the box?

So am I just screwed and have to reinstall the whole OS. This will be my third time, after running into problems I can’t figure out or can’t find help online. I really want to learn Linux but I’m starting to lose faith. I keep running into problems, not knowing enough to fix myself and unable to find any advice.

Hold off on reinstalling. You should be able to just force install the desktop metapackage and get all of the dependencies back. I don’t know what the metapackage is called though, as I don’t use Pop or gnome

Alright I’ll see if I can figure out the metapackage and dependencies. Thanks for the help

According to Ubuntu here, https://packages.ubuntu.com/disco/gnome-control-center, you need “gnome-control-center” and “gnome-control-center-data”.

Between the two above, you apt should pull in the dependencies.

apt update && apt install -f gnome-control-center gnome-conrol-center-data

The -f is to fix what ever is broken or partially installed in the current installation. You may need to switch to an actual tty.

Still having the same issue and same output in the terminal as my original post.

$ gnome-control-center

(gnome-control-center:11728): GLib-GIO-ERROR **: 15:18:07.196: Settings schema ‘com.system76.hidpi’ is not installed

$ sudo gnome-control-center

Install the following:

sudo apt install hidpi-daemon

It’s required because of latest Pop! OS improvements:
