Help needed for odd bspwm behaviour
(programming.dev)
Solution at the end of the post
Hello guys. I've recently started experiencing an odd issue with my bspwm setup where on a reboot or upon restarting bspwm in-place I either don't get the top polybar (fixed this by explicitly killing all polybar processes from my bspwm script if they exist and then on a separate line running my launch script), or the gap between the bottom of the windows on my top (secondary) monitor and the bottom edge of the monitor is far too wide. Here is a screenshot of what I mean:
Out of the 20 times give or take that I will restart bspwm either from the terminal or through the sxhkd keybind I set, only once will it actually size itself correctly with the proper gap. The next time I restart it will revert back to this large gap. Here is also my bspwmrc file
#! /bin/sh
# pgrep -x sxhkd > /dev/null || sxhkd -s &
# pgrep -io "sxhkd" || { killall sxhkd; sxhkd > /dev/null 2>&1 & }
pgrep -io "sxhkd" | xargs kill
sxhkd -s &
pgrep -x copyq > /dev/null || copyq &
pgrep -x xfce4-power-manager > /dev/null || xfce4-power-manager &
pgrep -x dunst > /dev/null || dunst &
pgrep -x nm-applet > /dev/null || nm-applet &
pgrep -x picom > /dev/null || picom -b
pgrep -x polybar > /dev/null || $HOME/.config/polybar/launch.sh
if [[ $(xrandr -q | grep "HDMI-A-1 connected") ]];
then
xrandr --output HDMI-A-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal
xrandr --output HDMI-A-1 --mode 1920x1080 --rotate inverted --above HDMI-A-0

bspc monitor HDMI-A-1 -d 6 7 8 9 0

The lines where I set bottom_padding for the secondary monitor and top padding for the primary monitor I just commented out but they did not have any effect.
I would really appreciate any help for this. Thanks in advance!
Solution for polybar not launching both bars is to change the single polybar line that checks for any existing instances and runs the launch script if none are found, to 2 lines that will explicitly kill all polybar processes and then run the launch script. I also moved this a bit further down in the file.
pgrep -x polybar > /dev/null | xargs kill
$HOME/.config/polybar/launch.sh
The solution for the gap on the bottom of the second monitor was to move the if check further down in the file, hopefully giving bspwm enough time to set its defaults and then have my values set. It now looks like this:
#! /bin/sh
# pgrep -x sxhkd > /dev/null || sxhkd -s &
# pgrep -io "sxhkd" || { killall sxhkd; sxhkd > /dev/null 2>&1 & }
pgrep -io "sxhkd" | xargs kill
sxhkd -s &
pgrep -x copyq > /dev/null || copyq &
pgrep -x xfce4-power-manager > /dev/null || xfce4-power-manager &
pgrep -x dunst > /dev/null || dunst &
pgrep -x nm-applet > /dev/null || nm-applet &
pgrep -x picom > /dev/null | xargs kill
picom -b
# THESE ARE THE 2 POLYBAR LINES WHERE THE FIRST KILLS ANY EXISTING PROCESSES AND THE SECOND RUNS THE LAUNCH SCRIPT
pgrep -x polybar > /dev/null | xargs kill
$HOME/.config/polybar/launch.sh
$HOME/.fehbg &
setxkbmap us
$HOME/.bin/remap-caps-esc
bspc config border_width 2
bspc config window_gap 10

# THIS IS THE CHECK FOR WHETHER THERE ARE 2 MONITORS CONNECTED WHICH I MOVED DOWN IN THE FILE
if [[ $(xrandr -q | grep "HDMI-A-1 connected") ]];
then
xrandr --output HDMI-A-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal
xrandr --output HDMI-A-1 --mode 1920x1080 --rotate inverted --above HDMI-A-0

Note: On booting into the WM the secondary monitor polybar doesn't launch, but it appears after restarting bspwm.
Im not entirely sure if my way of thinking is correct with regards to how bspwm handles the timing of setting default values and then reading its configuration file, but it seems to at least half work now.
