Using Ubuntu Gnome 16.04 I want my screens to stay on after locking. After locking ( Super + L ) I see the Curtain-Image for about one second before my screens go black. Once I push any key my screens need several seconds before they are showing anything again so I would prefer them to stay active all the time even when station is locked.

I already tried xset -dpms and some settings in gsettings but nothing worked for me.

How can I disable the timeout so the screens stay active?

EDIT: meanwhile updated to Ubuntu Gnome 16.10, still have the same issue

  • Did you check with the available options in the power management setting? – Arijit Chatterjee Nov 11 '16 at 09:21

  • @ArijitChatterjee the power management settings in systems settings are... not worth to be mentioned. Screen shutdown time is set to never but that's all regarding to screen settings. – viper1209 Nov 11 '16 at 14:25
  • @MaheshGareja I've had a look at this post but I can't find the setting from the highest rated answer. There is no gnome-power-manager within apps. And I did not know how exactly to implement the solution of the accepted answer. The mentioned line says GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", how do I have to add acpi=off and apm=off without messing with my grub settings? – viper1209 Nov 11 '16 at 14:29
  • @viper1209: What Mahesh suggested, seems to be a solution. In Gnome, there is gconf-editor (write 'gconf-editor' in terminal), if not, then install it with apt-get. Then rest will be easy. – Arijit Chatterjee Nov 11 '16 at 14:34
  • @ArijitChatterjee I know how it is meaned. I opened gconf-editor but there is no gnome-power-manager in apps. I looked through the whole tree (not every single value but the folders) to see if something got moved but there is nothing which seems to be what I'm looking for – viper1209 Nov 14 '16 at 07:24
  • Does no one has any more ideas? – viper1209 Nov 21 '16 at 07:45
