I installed a fresh copy of OpenBSD in KVM (GNOME Boxes), booted the system up and tried to launch Xorg. According to the FAQ, Xorg should usually work fine without any configuration and it kinda does.
I just have one little issue: Mouse input does not work. I attempted to solve the problem by running
xorg -configure, but it segfaults:
Sorry for the screenshot, but it doesn't seem like I'm able to copy&paste out of the VM.
Even though configure crashes, I am actually able to run Xorg just fine, only mouse input isn't working.
