[bug#56717] [PATCH v2 2/2] gnu: Add i3-autotiling.

[Hilton Chain via Guix-patches via <guix-patches@gnu.org>]

Thanks!

xvfb-run works well, however some "Fontconfig error: No writable cache directories"
occurs. I don't know what to do with this, do you have any ideas?

* Below attaching part of the build log:
