HiDPI scaling about mons

[Ventto]

Hello @pkhamutou. Thanks for the feedback.

Please, do you confirm the xrandr command line above is meant to display the second monitor only ?
If I understand this correctly, you use that command line because of your configuration on startup ?

I suspect the xrandr --auto (in mons) before performing the -s option.
I am investigating.

Hello @Ventto !

1. Yes, this xrandr command is only to display the second (FHD) monitor. I disable the laptop's display with --output eDP1 --off.
2. No, I run it manually just to connect an external monitor (there is no any other purpose).

Thank you!

Regarding your configuration, mons -s runs the following commands:

$ xrandr --output eDP1 --off
$ xrandr --output DP1 --auto --dpi 96

I tried to reproduce your configuration.
But I do not understand why you need to rescale your DP1 monitor to fit the eDP1 resolution:

--fb 3200x1800 [...] --scale-from 3200x1800 --pos 0x0 --panning 3200x1800+0+0

Turning off eDP1 and displaying DP1 with its own 1920x1080 resolution, is it what you want ?

Hey @Ventto !
Check out Multiple displays section from https://wiki.archlinux.org/index.php/HiDPI

And yes, I want to turn eDP1 off and use only external display.

but is there a possibility to make the same with mons ?

I am trying to keep mons as simple as possible (#21)
After some search, it can not make it without becoming partial copy of xrandr using xrandr itself.

So I recommend to keep using your custom command.
