@aral Hi Aral. Well my Librem has a loose video cable. When I open the screen either the backlight might not come on or the display feed. If I gently move the screen forward it pushes it in, and the screen comes on. However, if I move the laptop (ie: bring it to work) then the cable is loosened more and it requires, often, a lot of time to wiggle it into a working state. I bought a screen replacement from Purism, but there are not instructions on how to install it.
