Hello,

That sounds bad, like perhaps a KMS (=E2=80=9CKernel Mode Setting=E2=80=9D)=
 driver issue
or something.

Is the machine entirely dead at that point, or can you still log in via
SSH for instance?

Do /var/log/messages and /var/log/Xorg.0.log provide any useful hints?

As an aside, I=E2=80=99d recommend using QEMU (VirtualBox now requires a sm=
all
piece of non-free software to be built).  QEMU is known to work well
with Xorg and all (e.g., =E2=80=98guix system vm gnu/system/example/desktop=
.tmpl=E2=80=99).

HTH!
