Does the screen turn blank after a random time, or at the time of an event (like starting X, or starting an application, or some heavy processing etc). After a minute or half an hour? Is the screen really black or just very dark? What happens if you select a VC, or exit X? … … … > I've tried to debug the issue by looking a various log files (e.g., > ~/.local/share/xorg/Xorg.0.log, /var/log/kern.log, running > `journalctl`), but nothing would show up in these logs whenever it > occurs.
