I would like this thread to serve as a continuation of
https://github.com/emersion/kanshi/issues/43, since this is still an issue.

I would have left a comment in that thread as well, but the repository has been archived
thus I cannot.

The `exec_always pkill kanshi; exec kanshi` workaround didn't quite work for
me, my laptop display would remain enabled whenever I started sway. A reload
solved that, but it felt a little annoying to have to reload sway every time I started
my computer.

So, I adjusted the workaround a little bit and wound up with this:

exec_always exec kanshi; sleep 1; pkill kanshi; exec kanshi

I think that it could probably be stripped down a little further, but
this did work for me, and I'll be leaving it like this on my system.

Thought that this could be helpful for others who run into this!

hi, j3s again - ignore the workaround i had posted previously, it's
uninformed. here's a better one:

exec_always pkill kanshi; exec kanshi &> /tmp/kanshi.log

I have no idea why adding the stdout/stderr redirect fixes my issue,
but it does. On boot, my laptop screen now displays nothing
appropriately.

I have not tested the POSIX variant:

exec_always pkill kanshi; exec kanshi > /tmp/kanshi.log 2>&1

but I assume it would work as well. 🤷
