Often after I update #fedora it boots into a black screen with a mouse cursor only. No log in, and the terminal summoning keyboard shortcuts do nothing (mashing CRTL/AlT/SHIFT combinations and pressing t).
Sometimes powering off (long hold power button) fixes it, but generally not. When it occurs I don't get POST prior so can't select the old boot. It is like the system is resuming. But there is no fanspin between boots. When this happens I have to unplug to power cycle.
X570 motherboard, secureboot is on, Nvidea 4000 series GPU, with their drivers. No iGPU. I occasionally connect a second monitor via DP, but mostly 1 monitor via DP.
Has anyone else encountered this? It has been happening for months.
