This bug report concerns to the initial size of the system (not the

> After I log in (ubuntu session) the systen(?), shell(?) uses a lot of memory. When the computer has 2GB RAM, 1.2GB is used. When the computer has 4GB RAM, 1.7GB is used. When the computer has 8GB RAM, 2.2GB is used. I tried it out in virtualbox with a newly installed system. I changed the memory size and started ubuntu. I think a new, clean system should use the same amount of memory independently of the RAM size.
> Not to mention that the system is unusable, because RAM quickly fills up (memory leak?) and become laggy. Unity in 16.04 uses approx. 800kB memory. Why does gnome-shell need so much memory? I think it should be fixed, because 18.04 is an LTS release! I would like to work with it.Description: Ubuntu

Ah, sorry. If you're talking about 1.2GB used on login then you must be talking about the virtual memory size. That's not real memory - only address space.

For actual memory allocations see the VmData field in /proc/PID/status.

I think it's probably safe to call this a duplicate of bug 1759497 then.
