About one in 20 boot cycles on Ubuntu 18.04 with a GTX 1070, I get graphics issues on the text console. Really ridiculous corruption in some cases:
Setting nvidia-drm.modeset=1 in /etc/default/grub improves things, so that the system doesn’t hang or have obvious visible corruption. But still 1 in ~50 cycles xorg won’t come up and in each case I see nvidia-smi showing 100% GPU usage (where in normal boot cycles it’s at 0%). The xorg error I get is:
[ 21.625] (EE) AddScreen/ScreenInit failed for driver 0
At the moment the system has a more severe manifestation, with nvidia-smi hanging.
Here’s the bug report .gz:
