Yesterday, I closed the cover of my machine (Thinkpad T480S). This morning, it did not want to wake up anymore! The little white light (on the start button) was blinking slowly.
I had to press the start button for 10 seconds. The system restarted completely.
How to solve this problem? How to set the sleep mode on Qubes? How to get out of this sleep mode?
I’ve been to > System tools > settings manager > screensaver
… but I don’t understand all the settings and I haven’t found the solution to my problem.
I did not find any explanatory documents about screensaver or xscreensaver.
