If you so desire provide the following information/stats:
* The operating system(s) used and version thereof + 32 or 64bit, Debian, Arch, Bunsenlabs gnu/Linux etc ?
* Just to be anal is the install VM-virtual machine or bare metal (installed on a disk)?
* Which desktop environment(s) or windows manager(s) and the version numbers are involved ?
* Finally at bootup/start up memory stats (ie: via the "free -m" command, ps_mem etc) ? Also realise some nixers would rather swallow their tongue than reboot, so if that's you, how about just shutting everything but the bare minimum down for this. Though if so inclined share your systems uptime too.
Since this my hair brained thread, only right I should start.
#1. Bare-metal Debian 9.8 32bit netinstall, openbox v 3.6.1-4, memory at bootup = 85mbs-ram according to the free -m command. While ps_mem is reporting 103.8mbs.
Note: Though ps_mem also tells me the terminal I'm using to run these commands in is using 17mbs of that, so it's 103.8 - 17 = 86.8mbs. Yep ... I'm anal.

#2. Bare-metal Debian 9.7 64bit netinstall, with openbox 3.6.1-4, memory at bootup = 117mbs-ram free -m, whereas ps_mem says 120.4mbs - 25.8 (for the pesky terminal again.) comes out to 94.6mbs.
Well that's my stats folks and welcome to the gnu/Linux OS/desktop/windows manager memory SHOWDOWN !!!
