Since I've installed kubuntu 19.04 my computer is not able to boot all the time. I thinked it was a grub option because some things are changed from the previous version 18.04 (which works fine for me), but in fact I can make nomodeset [nouveau/nvidia].modeset=0 or many other strange things, my computer just get stuck on black screen once in five.
By the way, it makes the same trouble with the installation media
And if I press the esc key on boot, it just stay black and doesn't change anything …
config of my pc : i7 8650U + gtx 1050m
(Please correct me if my english is bad and you want to help me 😉 )
