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 😉 )

In GRUB, press
e
to edit the linux startup command line and adddis_ucode_ldr
at the end of the line that starts withlinux /boot/...
so that the line will look something like:and you'll be able to boot.
(Remove
quiet splash
if you want to check the system boot logs).Add the same parameter
dis_ucode_ldr
toGRUB_CMDLINE_LINUX_DEFAULT
in /etc/default/grub:then run
and then you should always be able to boot, as-is, so without editing the command in GRUB.
