Description

The primaryScreenChanged signal is not fired when changing primary display with xrandr in Linux.

  xrandr --output DP2-1 --off
  xrandr --output eDP1 --primary --mode 1366x768 --pos 0x0 --rotate normal --dpi 96x96
  xrandr --output eDP1 --off
  xrandr --output DP2-1 --primary --mode 3440x1440 --pos 0x0 --rotate normal --dpi 102x102

#!/usr/bin/python3
from PyQt5 import QtWidgets

def screenChanged(self, *args):
    print("Screen changed")

app = QtWidgets.QApplication([])
app.primaryScreenChanged.connect(screenChanged)
core = QtWidgets.QMainWindow()
core.show()
app.exec()
