Nope, doesnt seems to do anythingThere is some information on the internet. Try exporting autoscaling to Off(0) and applying a factor in ~/.profile:
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCALE_FACTOR=1.5
# $FreeBSD$
#
# .profile - Bourne Shell startup script for login shells
#
# see also sh(1), environ(7).
#
# These are normally set through /etc/login.conf. You may override them here
# if wanted.
# PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:$HOME/bin; export PATH
# Setting TERM is normally done through /etc/ttys. Do only override
# if you're sure that you'll never log in via telnet or xterm or a
# serial line.
# TERM=xterm; export TERM
EDITOR=vi; export EDITOR
PAGER=less; export PAGER
# set ENV to a file invoked each time sh is started for interactive use.
ENV=$HOME/.shrc; export ENV
# Let sh(1) know it's at home, despite /home being a symlink.
if [ "$PWD" != "$HOME" ] && [ "$PWD" -ef "$HOME" ] ; then cd ; fi
# Query terminal size; useful for serial lines.
if [ -x /usr/bin/resizewin ] ; then /usr/bin/resizewin -z ; fi
# Display a random cookie on each login.
if [ -x /usr/bin/fortune ] ; then /usr/bin/fortune freebsd-tips ; fi
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCALE_FACTOR=1.5
QT_QPA_PLATFORMTHEME=qt5ct
export QT_FONT_DPI=128
yes i did executed it, lemme try to put all of this in xinitrc file, and i'll give the results if it worked, or not.Your "QT_QPA_PLATFORMTHEME=qt5ct" f.e. should be set for your whole X session, and not just for a shell (f.e. those settings in ~/.profile wouldn't make any effect on my system); So I recommend to set this either in ~/.xsession or ~/.xinitrc (the one you are using on your setup) before the window manager or desktop environment starts (alternatively there might be something like an autostart option within your desktop environment, which allows you to set such variables).
And just to be sure…: As you set this variable to "qt5ct" … of course you installed the corresponding port/package "misc/qt5ct" - and executed it?
Five questions:Nope it did nothing :/
echo $QT_QPA_PLATFORMTHEME
say "qt5ct"?grep -A2 Fonts ~/.config/qt5ct/qt5ct.conf
that there are font settings?
