I have no idea how to find out.

I tried this ~/.xinitrc first at a test:

Then I tried:

#!/usr/bin/env bash
#xrdb -query | grep -v Xft.dpi | xrdb -load &
export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LANGUAGE="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
echo "Xft.dpi: 120" | xrdb -override
exec /usr/bin/xterm &
exec openbox
#exec cinnamon-session

That got an xterm open, from which I entered xrdb -query | grep Xft to find
120, then strace cinnamon-session 2>&1 | grep open. Screen went black, then I
was returned to shell prompt from which I ran startx. So next I tried this
~/.xinitrc:

#!/usr/bin/env bash
#xrdb -query | grep -v Xft.dpi | xrdb -load &
export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LANGUAGE="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
echo "Xft.dpi: 120" | xrdb -override
exec /usr/bin/xterm &
#exec openbox
exec strace cinnamon-session 2>&1 | grep open

That got both xterm and cinnamon session going, but left no output anywhere I
could see or find, including not touching .xsession-errors. lsof|wc -l
produces 12363. Whether I should be able to find a clue in lsof output I have
no idea, so maybe it's time to find cinnamon people to ask how it's supposed
to work.

That would surprise me none.

Again, thank you!
