Here is an updated version of my scripts to block GNOME apps and services leading to an HTOP RES of 389MB from a default of 980MB. After running the scripts and rebooting I was able to start all installed by default apps, but discovered the GNOME Software app does NOT display installed or searched for apps. GNOME does come with Synaptic which is broken in wayland unless you run it from a CLI as /usr/sbin/synaptic (no root required). In this mode Synaptic won't install apps but you can identify them and install them with apt. The last two blocks of the first script can be commented/uncommented to allow the GNOME Software app to run at the cost of using an additional 90MB of RAM or save 90MB of RAM and keep it disabled.
My method to keep apps from starting is moving them into a maybelater directory in the app’s current directory. There must be a better way. If I could modify the configuration which starts the gnome-software app I could leave it in /usr/bin and when the GNOME Software app is started by the user only then would it consume extra memory. Basically I’ve identified noncritical apps and services but there must be configuration files which cause the apps and services to start when the system boots.
I've destroyed about 30 VMs while testing these two scripts so I absolutely would NOT use this on anything but a sacrificial VM with NO data.
This needs to be executed as sudo:
Followed by this script - not sudo:
