Hello,
Very similar situation here with an ASRock N3150M motherboard. This board has
DVI, HDMI and VGA ports, of which I'm using just the DVI. The Xubuntu 18.04
Bionic Beaver i386 DVD fails to bring up the window manager with a GPU hang.
What works: nomodeset
What doesn't: bootstring intel_iommu=off (a solution proposed elsewhere)
When nomodeset is NOT used, nine times out of ten a single underscore
character appears at the top left of the screen and the kernel is
unresponsive (Alt-SysRq-h does nothing), however it is occasionally
possible to get a mouse pointer on a blank screen and switch to console
from there.
I was able to retrieve /sys/class/drm/card0/error and will attach.
Also some related info from logs, please see below.
Regards.
