[Bug 1801716] Re: Xorg freeze (black screen after ubuntu logo during boot)

I am so so so sorry for I made a mistake of selecting the wrong kernel
with the wrong architecture to install, which lead to all those error
messages during boot in v4.19. (My laptop should install the kernel with
architecture amd64 but I installed i386, I am so sorry for making things
more complicated, SORRY!!!)

Anyway, I "apt purge" the wrong kernel (4.19 with architecture i386) and
just installed the proper one(architecture amd64).

However! The issue in the v4.17 remain in the 4.19! I don't see anything
improve in my situation, I still can't get in the system, getting stuck
in the black screen after the Ubuntu logo during the boot, I can only
access the system in recovery mode; the brightness of my display can't
be adjusted; the setting for my display still says "Unknown Display",
and the laptop can't get back if I put the whole system into sleep
mode(by turn off the display)

Any idea? Please help!!!! Thanks in advance!

Title:
Xorg freeze (black screen after ubuntu logo during boot)

Status in linux package in Ubuntu:
Incomplete
Status in xorg-server package in Ubuntu:
Incomplete

Bug description:
I experienced this bug ever since I have upgraded my laptop from
16.04. But it got resolved in my last update after I reported the bug.
However, I forgot to go back to Launchpad to mark it as resolved and
now the problem comes again after I just updated the system.

So, as the title stated, I can't get in the system due to the infinite
black screen I am facing. I am only able to report this bug under the
recovery mode.

Besides, there's something wrong with the lock screen too. I can't get
back to the system if I just put the system into "sleep mode". Black
screen again!

What's worst, the brightness of my display can't be adjusted as well!
I feel like being blind at night! Please help!!! Thank you!

And I think there might be the compatibility problem between my laptop
and the new desktop -- Gnome, which is the default in 18.04.

What should do? I really love using Ubuntu, as I really learned a lot
in these days I used it as my study os for CS.

Any help is appreciated, thanks in advance!
