[plug] blank screen issue

[lhuck]

My 'two cents' would be to check what GPU driver is being used, then try a different one and see if the problem repeats.


Best of luck,

Every now and then, usually when trying to launch some full-screen video, the monitor blanks to just the backlight glow, the NUC fan speeds up and the keyboard is unresponsive. Because of the last factor, no amount of cntrl+BS, ctrl+alt+del, or trying to open a VT works. I have to do a hard reset. Any ideas of any other HW / keyboard options I can try, or even better, if there is a setting I need to look at to prevent this happening?
