I encountered this GPU hang today and I think it's related to the way the Intel
HD driver allocates VRAM for Vulkan in Linux. I tested the game Darksiders 3
with DXVK 1.3 (as of writing).

I have 2 systems both running a freshly installed Xubuntu 19.04.

1st System: Desktop with i3-7100 CPU and 8GB RAM (DDR4 2400MHZ) - The game
freezes soon after Launch with no possibility to switch to any tty's and close
it. A hard reset was required.

2nd System: Laptop with i3-5005U and 16GB RAM (DDR3 1600MHZ) - The game runs
and plays without issues. See Screenshot: https://i.imgur.com/R3DLG9N.jpg


With these results I believe that the Intel HD allocates 1GB V-RAM on a system
with 8GB Ram whereas with 16GB it allocates 2GB V-RAM.

Further inspection of this I ran the game on my main gaming system with a
GTX1060 6GB, the game was already hitting 1GB V-RAM.

Unfortunately I lack the skills to go deeper in this.
