I had something similar happen to me, repeatedly, recently; after the screen saver kicked in (goes blank) I would have to reboot the system. Hunting about (I do not remember exactly how I stumbled upon it) it was due to firefox (org.mozilla.firefox) inhibiting the power manager. I could click on the (Xfce) Power Management Plugin and see: org.mozilla.firefox is currently Inhibiting power manager
I take it that when firefox is in fullscreen mode (looking at firefox playing video fullscreen) it issues a message to the GDBus? to inhibit the power manager from kicking in. I think if I kill firefox before it can issue the cancel message, the power manager is still inhibited. I am now very careful about when I kill firefox (Also, I do not let firefox simple run when I am not using the computer because it tend to eat up memory...). I tried to use d-spy to artificially send a cancel message, but when I tried that, it really froze my system. Any way, maybe its something to look at.

similar to earlier thread. System goes blank and does not resume from wherever. Using LXDE and have set all the suspend, etc. options I can find to never. I can access the system from firefox on another machine and open a terminal. Is there a command that will restart the graphical display?
I've used pkill -u "user" to drop back to the display-manager but really want to get to the session as operable or to have it never go into stasis.
