Re: Power management

[Iosif Fettich]

Hi,

merely out of curiosity, I asked your question on ChatGPT. Here's the answer:

To prevent Fedora from going to sleep when no user is logged in, you can modify 
the power settings and systemd configurations. Here are the steps to change 
this behavior:

1.    Open Terminal: Open a terminal on your Fedora system.

2.    Check the Current Power Settings:
     To see the current power settings, you can use the following command:

bash

gsettings list-recursively org.gnome.settings-daemon.plugins.power

This will show you the current values and settings for power management.

3. Modify Power Settings:
To change the behavior when no user is logged in, you can set the 
sleep-inactive-ac-timeout and sleep-inactive-battery-timeout values to -1, 
which effectively disables sleep. Run the following commands:

bash

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 
-1
gsettings set org.gnome.settings-daemon.plugins.power 
sleep-inactive-battery-timeout -1

4. Check Systemd Configuration:
You should also check your systemd configuration to ensure that it's not 
overriding your power settings. Run the following command to display the 
current settings:

bash

sudo systemctl show sleep.target

Look for a line that starts with InactiveExitTimestamp. If it's set to yes, it 
means the system will go to sleep when no user is logged in. To disable this, 
run the following command:

bash

sudo systemctl mask sleep.target suspend.target hibernate.target 
hybrid-sleep.target

5.    Reboot: After making these changes, it's a good idea to reboot your 
system to ensure that the new settings take effect.

After following these steps, your Fedora system should no longer go to sleep 
when no user is logged in, even when the power mode is set to "performance."

Seems quite ok to me...

Done. It worked.

This is sort of the solution.  However, it needs to be run as the gdm 
user with "sudo -u gdm".  "gsettings get" works, but the set fails with 
a dbus error.

This isn't used in Fedora.

This part probably works to disable suspend and hibernate always, which 
could be ok if that's what you want.
