Problems with bspwm with multiple displays

Question

I am trying to setup bspwn on a multi monitor setup. I have an ultrawide 21:9 (2560x1080) and a standard 16:9 (1920x1080). So far I have gotten it working so that it loads the window manager properly on both screens but the monitors are the wrong way arround.

How they look on my desk
##########    ##################
#        #    #                #
#  16:9  #    #     21:9       #
#        #    #                #
##########    ##################

How the monitors are displayed in bspwm
##################    ##########
#                #    #        #
#     21:9       #    #  16:9  #
#                #    #        #
##################    ##########

So I tried to fix the position of them by running a xrandr command

xrandr --output DP-1 --primary --mode 2560x1080 --rate 75.00
xrandr --output HDMI-1 --mode 1920x1080 --rate 60.00 --left-of DP-1

Afterwards my first desktop on bspwm always defaults to the 16:9 display when I want it on my 21:9. I think that when I run the xrandr commands the screens switches positions bspwm going of the positions relative to other monitors. Is there some way that I can switch the displayed positions of the monitors without it messing with bspwm?

Answer 1

After playing around with it for a few hours I tried to use arandr since I might not be doing something correct with xrandr and got the xrandr command that works for me.

xrandr --output DVI-I-1 --off --output DP-1 --primary --mode 2560x1080 --pos 1915x0 --rotate normal --output DP-2 --off --output DP-3 --off --output HDMI-1 --mode 1920x1080 --pos 0x0 --rotate normal

EDIT: Above just moved the monitors so that they were switched around and not lined up properly which I found out when setting up lemon bar.

I just figured out the commands which setup the monitors then swaps them

bspc monitor DP-0 -d IV V VI
bspc monitor HDMI-0 -d I II III
bspc monitor DP-0 -s HDMI-0
