            Bug ID: 353040
           Summary: After upgrading to frameworks 5.14, KDE ignores xrandr
                    DPI setting
           Product: kde
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: m.liu.jin at gmail.com

I run "xrandr --dpi 168" in .xinitrc, before /usr/bin/startkde. In frameworks
<=5.13, this always works. But since I upgraded to 5.14, all KDE applications
and Plasma shell no longer respect this setting, and all UI elements are much
smaller than before.

If I run "xrandr --dpi 168" again after KDE startup, then any newly launched
KDE application would restore to the old behavior -- correctly sized UI. (The
only exception is the "Screen Scaling" dialog in systemsettings, where the UI
example is still small.) But UI in already running applications like Plasma and
kwin decorations would remain small.

Reproducible: Always

Steps to Reproduce:
1. Use a Hi-DPI screen.
2. Run "xrandr --dpi 168" in .xinitrc, before /usr/bin/startkde.
3. Reboot and start KDE.
4. All UI is too small.
5. Run "xrandr --dpi 168" in konsole.
6. Launch Dolphin.
7. UI in Dolphin is larger, where other applications remain small.


Expected Results:  
UI size should be normal when KDE starts.

My .xinitrc:

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

export DESKTOP_SESSION="plasma"

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"
xrandr --dpi 168
xset -b
eval `ssh-agent` 
xbindkeys

exec /usr/bin/startkde
