Fedora 29 XFCE4 wm, fresh install
Latest 4.19.9 and 4.19.10 kernels, after update booted into blank
screen, I thought, that it is, because of darkest time here, 5h20min
daylight :) :).
But found somewhere from net solution.
I have laptop HP 15-bw021na, with AMD 4 core processor, AMDGPU.
Had to add into linux cmdline AMDGPU.DC=0, after that booted OK.
Now, something with these "new" kernels is going wrong? because
with 4.19.5 kernel does not need amdgpu.dc=0 command.
So, if someone counter same problem, this might help.
Happy Holidays
