SOLVED: Can't move or resize any windows after installation
Also, the minimize/maximize/close buttons didn't work. This happened to me on both installs (two different laptops). I was able to find enough of a clue online to try a few things and get it fixed. But the solution wasn't stated clearly anywhere that i could find, and it was not in relation to Artix. Thus this post.
When this happened, again, on my 2nd install, i was able to pinpoint exactly what fixed it:
rm ~/.config/openbox/rc.xml
I have no idea *why* this particular file causes the problem, but once you delete it, it gets recreated and everything then works fine.
