I have a QHD+ laptop and successfully changed the text scaling using gnome-tweak-tool. I am now just trying to figure out how I can scale the rest of the windows throughout kali linux so that everything is uniform. Looking online it was suggested to run this command: gsettings set org.gnome.desktop.interface scaling-factor 2. I assumed this scaled the whole desktop evironment's interface, but I got this error: No such key 'scaling-factor'.

Is this an issue since I am running Gnome-Fallback? Would upgrading to gnome-3 help solve my High DPI issues? I heard there were issues with gnome-3 with losing kali menus...

Any help is appreciated I am new to Kali.
