"Put to sleep after" -- Blanks Display #2 and Toggles "Mirror Displays"

Example 2: Settings > Power Manager > Display > Display power management > Put to sleep after
-- Set "Put to sleep after" at 20 minutes . . . after 20 minutes, Display #2 is blanked, Display #1 is not blanked.
-- Upon keyboard interaction of mouse movement, Display #2 resumes and is in a "mirrored state" with #1.
-- Requires returning to Settings > Display and UnChecking "Mirror displays" to return to normal.


!! Using Two Displays: #1 Display Port (primary) -- #2 HDMI

Thank you for the pointer on the "code" tag. I apologize for that.

Please use code tags. And please explain which expected behaviour does not work and what happens instead. I don't get it. Or maybe I'm too dense?

Something is afoot . . .

Power manager set to test:
-- Blank after: 1 minute
-- Put to sleep after: 2 minutes
-- Switch off after: 3 minutes

1) At 1:00 minute, both displays actually went blank for 10 seconds, then returned with Display #2 mirroring Display #1.
2) At 2:10 minutes, both displays went blank for 10 seconds, Display #1 returned - Display #2 was blank.
3) At 3:20 minutes, both displays went blank for 10 seconds, Display #1 returned - Display #2 was blank.
4) At 4:30 minutes, both displays went blank for 10 seconds, Display #1 returned - Display #2 was blank.
5) After 1 hour, Display #1 was not blank, Display #2 remained blank. Keyboard or mouse movement would not activate Display #2.

-- At this point opening the Display settings and "Unchecking" Mirror displays activated Display #2 and normal display resumed.

WORK-AROUND to Blanking Displays with a **Dual Monitor Desktop** Setup

Note: Power Manager appears to work fine on my Single Monitor Setup. However, since the Dual Monitor Setup is my daily driver, the "work-around" is suitable for my needs.

1) Switch Power Manager OFF
-- Settings > Power Manager > Toggle OFF

2) Disable Power Manager
-- Settings > Session and Startup > Application Autostart > UNCHECK Power Manager

3) Disable DPMS (Display Power Management Signaling) at Boot
-- as ROOT, create /etc/xdg/autostart/DISABLE-DPMS.desktop

Code: Select all

[Desktop Entry]
Type=Application
Exec=xset -dpms
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[en_US]=DISABLE-DPMS
Name=DISABLE-DPMS
Comment[en_US]=Disable DPMS at Boot
Comment=Disable DPMS at Boot

4) as ROOT, apt-get install xscreensaver xscreensaver-data

5) Reboot

6) Double Check Screen Saver is CHECKED in Session and Startup
-- Settings > Session and Startup > Application Autostart > CHECK Screensaver

7) Validate Power Manager is OFF
-- Settings > Power Manager !!! DON'T Re-START IT !!!

8) From a terminal run: xset -q
-- the last line of output should read DPMS is Disabled

9) Through the Menu, open the Screensaver application and configure.
-- I do not use, nor was the Screen Lock activated.

That's it . . . Good Luck, it worked for me!

The XFCE power manager has always been a bit ... special. Thank you for posting your solution.
