I'm switching from i3 to xmonad on Ubuntu 18.04.4 LTS and hitting a weird problem.
Upon logging in xmonad appears to start without a problem, but closing a window with mod-shift-c reveals a problem. The window closes but my display is not updated. It literally looks as though the window is still open. Another more obvious problem presents itself when dragging a window with mod-button1:
If I run compton both symptoms go away immediately. Compton (0.1~beta2+20150922) was installed from my use of i3 and I only ever ran it for transparency. I didn't need it to make the window manager usable.
It's also strange that I'm experiencing this problem at all since xmonad.hs contains the following start-up hook:
------------------------------------------------------------------------
-- Startup hook
-- Perform an arbitrary action each time xmonad starts or is restarted
-- with mod-q. Used by, e.g., XMonad.Layout.PerWorkspace to initialize
-- per-workspace layout choices.
--
-- By default, do nothing.
myStartupHook = do
spawnOnce "compton &"
------------------------------------------------------------------------
However compton isn't starting (I checked the processes). I have to start it using dmenu or from the terminal.
xmonad.errors is empty so I'm unsure how to debug this further.

Well, I don't know if your query is still relevant today, but I faced the same issue on ArchLinux while using XMonad and Qtile too. None of the programs in my startup script would work. It then struck me that the only change I had made here compared to my old config was that I was using the 'mate-polkit' instead of the previous 'lxsession'. And voila, when I changed my polkit back to lxsession in my 'autostart.sh' (startup script), it suddenly started working. While I can't explain the exact reason behind the occurrence, it certainly has piqued my curiosity enough that I'll try looking into it!
For more info on Polkit:
The config I used as a reference for my config:
Their dotfiles repo explains pretty much most of the stuff you need to get started and has some really good TWM configs, do have a look!
P.S: The configs are all for an Arch-based system. You'll have to keep that in mind if you're gonna use them for yours...
Hope this helps you, cheers!
