xfce4-power-manager: cannot get screen to turn on after it goes blank

werew · 2019-09-03 14:40:40

Hello smile

I have set xfce4-power-manager to blank the screen after few minutes ("Blank after" option in Power Manager > Display). However once the screen goes blank is it not possible to turn it on again pressing any key or moving the mouse. I also tried to close and re-open the lid (causing the laptop to suspend) but it doesn't work.
The only way is to restart the computer.

I hope you can help me solve this problem.

Here is my power-manager config:

$ xfconf-query -c xfce4-power-manager -lv

I also tried to use directly xset to blank the screen. It works correctly: moving the mouse turns the screen back on.

xset dpms force off

Which distro, version of Xfce and version of xfce4-power-manager are you running?
Also, which video card and drivers do you have as well as which display manager and screen saver.

Have a look at this bug report to see if anything there from the linked launchpad bug report help.

Thank you very much. Seems like I was able to fix the issue using the workaround proposed in the bug report.

Distro: Arch
Xfce version: 4.14
Power manager version: 1.6.5
Video card: Intel Corporation UHD Graphics 630
Driver: i915
No display manager
Using slock as screen saver

Adding the following entry to /etc/X11/xorg.conf makes the screen go back:

Section "Device"
    Identifier "intel"
    Driver "intel"
EndSection

Also, as pointed out in the launchpad report, setting "blank after" to never, both "put to sleep after" and "switch off after" works correctly (switching the screen off and making it come back on key-press/mouse move).

So the modesetting driver is causing the problem. Interesting.

Also, as pointed out in the launchpad report, setting "blank after" to never, both "put to sleep after" and "switch off after" works correctly (switching the screen off and making it come back on key-press/mouse move).

If you revert back to the modesetting driver, does making only these changes result in a positive result?

Yes, it works without touching xorg's config
