When I first installed Lubuntu it worked fine for months. Now when I startup there is this rapid flicker between the display (both the login screen and the general interface after I log in) and black at a rapid clip (like 5-10 alterations per second) for a good while. I haven't exactly timed it but it seems to last progressively longer, maybe around a full minute this time.
Eventually it seems to stop but I'd like to know if there's a way to figure out what is causing it, and maybe a way to fix it. Like if it might be hardware (the monitor or video driver) or something software?
Please tell me if there is something I could input into the terminal to give you information on how to answer this?
