- normal boot: display screen goes dead black as sson the i915 module is loaded
(monitor reports NO VGA SINAL);
- with "i915.modeset=0" on bootloader: boots and displays alright but leads to
no X desktop session;
- with "nomodeset": boots screen and starts X alright, although extremely slow
and unusable.

Occurs on all Linux 5.3 kernels to date (including 5.3.6)
