remains blank so in the dark you can continue to see the blank screen glowing light
I have the same issue sometimes under R4.0. What always fixes it for me:
- open “Scrensaver”
- File | Restart Daemon
- Advanced | Display Power Management …
- uncheck and re-check “Power Management Enabled”
- uncheck and re-check “Quick Power-off in Blank Only Mode”
The last option is the one that needs to be checked for the effect you wish to see. However every now and then it seems to stop working and I do the dance above.
