Comment 0 for bug 1773232

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.

Is there anything more I can do to make this bug report more specific?
