I'm not a completely new user of Ubuntu/Linux, but I'm still by far a novice.
I also am not 100% certain what all information is needed (and/or how to get it), so please let me know what I'm missing.
My problem is that occasionally, when booting, after GRUB comes up, it will flash a few times and go to a blank/black screen. The display is clearly on and lit, but it shows nothing. No cursor, nothing. It will play the startup sound, but I have to do a hard shutdown and turn it completely back on to be able to log in.
I find it odd because I have a much older laptop (a Fujitsu Lifebook) that has many other problems, but I never have this problem.
I also have taken note that the standard startup process that Ubuntu is apparently going through is not displayed for me. It's my understanding that there is a splash screen that is displayed during boot - I never see it. I consistently, after grub, see a black screen that flashes. Eventually, it will typically load to a blank screen with cursor and then the login screen. Other times, it's the blank black screen that's on.
I've not seen this happen after I've returned from sleep mode. It only seems to happen when I am starting up.
I have a dual-boot with Windows 10, but I am not sure it has any relevance. Also, I apologize for the length but I don't know how to put all the LSHW results into their own separate scrolling window within this post.
