mightyspaceman, So the new laptop has a slight issue. Every now and then a sliver of the top of the screen flickers white...it has done the same on linux/KDE, windows and even a tty shell, so it's probably a hardware issue, right?
Loose screen connector maybe? I'm scared to re-connect the connector because on my old laptop it took a lot of fiddling to get it back in and working.
