Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced. If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.

Title:
Not booting at all times

Bug description:
I'm running Linux kernel 4.17rc5. (this problem is also with the 4.16
kernel and 4.15). My computer randomly freezes up after a hour of less
and sometimes it works for more then a day. But when I check the
kern.log or syslog it does not show any messages at the time of
crashing. So is there a way that I can find you why it crashes?
Also, after a crash it sometimes refuses to boot at all. It will give
me a black screen. After restarting for 20 or more times it boots up.
Sometimes my password doesn't work while booting even though I use the
same (correct) password after the restart.
I have made a video on this issue here:
https://www.youtube.com/watch?v=gqH8ySXOUmk&feature=youtu.be
(the video is a bit out of focus, forgot the manual focus. I have speeded up
someparts to make it more pleasant to watch)
I'd like to include some logs but Can't find any relevant logs since
it does not log during the period of the error. I Have attached a
picture of my screen that it will sometimes show.
The moment it did boot up I was using kernel 4.15 (but with that version not
all of my screens work)
After the reboot I used the kernel 4.17r5 again and it did work.
This happens to me a lot and it can take a lot of restarting in order to boot.
In the video it didnt show the problem that my password would not be
recognised. However this sometimes happens too.
One more bug I'm having is that my thrird screen is not being recognised to
it sets a lower screen resolution. I have solved this with forcing the screen
resolution to 1080x1920 but then the menu bar is not shown correctly. and I
have to drag the screen to the right place in the settings in order to have the
menu's correctly.
(video: https://youtu.be/Tq-TEeAAIGA) this is what I have to do at startup
Is there anything more I can do to make this bug report more specific?
