A few questions: 1. Can you make sure that powerdevil is running? You can check with `ps -ef | grep powerdevil` in a terminal window. 2. Does the system (not the screen, the whole system) go to sleep as the correct time, or is that broken too? 3. On the PC, how is the screen connected? What connector type does it use? Is it DisplayPort? 4. Does this work in the X11 session?
Powerdevil remains active. System does not sleep. PC uses DVI-D, no adapters X11 works as expected, on laptop screen dimming works. presentation mode not invoked. manual sleep block not invokded.
Thanks!
