Few days ago I discovered wakeup from sleep is working on my laptop. Earlier, only black screen with blinking cursor is displayed.
It works on kernel 7.0.9-2-default. I update kernel to 7.0.10 and have need to test it again (more use cases, like watching video on FF) and discovered wakeup from sleep do not work again (the same effect with black screen).
How to gather info and report this bug?
Black screen with blinking cursor might be a sign for a graphic driver issues.

There are also reports for black screen after suspend:

Because I have hardware that is related to this topic I decided to compile kernels using git bisect and understand, which commit made problems. Any advice on what I should take a look? Is there any dangerous case, which I should avoid? Are there any descriptions, which patch requires which other patch? How long kernel is compiling?
