Update 0.22.1-1 on Arch break LightDM

See original GitHub issue

The issue:

After the last update on Arch which is version 0.22.1-1 LightDM could not start Qtile anymore, after entering password, LightDM is stuck in a loop. Killing lightDM and using qtile start from TTY1 show the following errors :

Traceback (most recent call last):
  File "/usr/bin/qtile", line 8, in <module>
    sys.exit(main())
  File "/usr/lib/python3.10/site-packages/libqtile/scripts/main.py", line 66, in main
    options.func(options)
  File "/usr/lib/python3.10/site-packages/libqtile/scripts/start.py", line 88, in start
    q = make_qtile(options)
  File "/usr/lib/python3.10/site-packages/libqtile/scripts/start.py", line 51, in make_qtile
    kore = libqtile.backend.get_core(options.backend)
  File "/usr/lib/python3.10/site-packages/libqtile/backend/__init__.py", line 15, in get_core

    raise QtileError("No DISPLAY set")
libqtile.utils.QtileError: No DISPLAY set

I also tried with a different display manager (SLiM)

Hi.

Using sddm as the display manager, qtile was started.

My friend uses a combination of lightdm and cinnamon. He said that after he upgraded packages, cinnamon would not start. It seems that there was an update to the lightdm package. This seems to be a lightdm problem, not qtile.

I will use sddm to work around this problem for now. Thanks.
