To Reproduce Created a libvirt virtual machine on an ubuntu-22.04-desktop-amd64 host following this tutorial: https://blog.tmm.cx/2020/05/15/passing-an-intel-gpu-to-a-linux-kvm-virtual-machine/

With the exception that it was UEFI instead of SeaBIOS by using the workaround described here: https://wiki.archlinux.org/title/Intel_GVT-g#Using_DMA-BUF_with_UEFI/OVMF

Tested it with ubuntu-22.04-desktop-amd64.iso Live CD to verify that it worked.

Installed FreeBSD-14.0-CURRENT-amd64-20220722-8f733dabcc3-256882-disc1.iso guest on same virtual machine.

Installed a desktop environment following these instructions: https://freebsdfoundation.org/freebsd-project/resources/installing-a-desktop-environment-on-freebsd/

startx does not display desktop. It shows a black screen with white block cursor in upper left corner.
