In trying to reproduce, I found on TW and 15.3, both work as desired using the following:
xrandr --dpi 108 --output DP1 --primary --mode 1680x1050 --scale 1.142858x1.028571 --pos 0x1080 --output HDMI1 --mode 1920x1080 --pos 0x0
The scale factor used allowed a fullscreen window from the 1920x1080 display to be moved and fit perfectly on the 1680x1050 (primary) display. There was no need to create any mode or use --fb.
good. It worked also for me on an other computer, but not on this one (who knows why??), but I will try your setup, thanks
Same PC, using default (modesetting DIX) driver, instead of intel DDX driver, this works: xrandr --dpi 108 --output DP-1 --primary --mode 1680x1050 --scale 1.142858x1.028571 --output HDMI-1 --mode 1920x1080 --above DP-1 When I tried --pos for both outputs instead of 1920x1080 --above DP-1, it was ignored. For most intel IGPs since around 2008, the intel DDX (xf86-video-intel) is deprecated. IIRC it isn't even installed by default in latest oS releases. The xf86-video-intel package hasn't had an official release in over 7 years: https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
