I have a machine that I access only via SSH that I just updated to Debian 10 a couple of days ago. Since the update it seems to be going to sleep when it is inactive. This has never happened with previous updates like from 7 to 8 or from 8 to 9. It seems like maybe the sleep settings have reverted to a default state. How can I view and edit the power and sleep settings in the command line? Any guidance much appreciated. Thanks!
I ran into this with
gdm3 after upgrading to Debian 10: whenever the computer was left at the initial login screen, it would go to sleep after a while.
To fix this, I had to edit the power settings for GNOME when running the
gdm3 session; these are stored in
/etc/gdm3/greeter.dconf-defaults, and the lines to edit are those in the “Automatic suspend” section at the end of the file:
# Automatic suspend # ================= [org/gnome/settings-daemon/plugins/power] # - Time inactive in seconds before suspending with AC power # 1200=20 minutes, 0=never # sleep-inactive-ac-timeout=1200 # - What to do after sleep-inactive-ac-timeout # 'blank', 'suspend', 'shutdown', 'hibernate', 'interactive' or 'nothing' sleep-inactive-ac-type='blank' # - As above but when on battery # sleep-inactive-battery-timeout=1200 # sleep-inactive-battery-type='suspend'
Specifically, I changed
'blank'. Despite its name, this isn’t a template file which should be copied; the change must be made in the
/etc/gdm3/greeter.dconf-defaults file itself. The changes are taken into account after restarting the
I didn’t have to make any changes to the systemd or logind setup; this means that if I want to, I can still suspend the system manually.
you can try the following based on your needs:
Disable suspend and hibernation:
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
To re-enable hibernate and suspend use the following command:
sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
If you just want to prevent suspending when the lid is closed you can set the following options in
[Login] HandleLidSwitch=ignore HandleLidSwitchDocked=ignore
restart the service or reboot your machine
systemctl restart systemd-logind.service
I made the changes in
/etc/gdm3/greeter.dconf-defaults and indeed this does stop the sleep while waiting at the GDM screen. However if you do logon to, e.g., gnome, then again after about 20 mins the same sleep reoccurs.
N.B. I have set the gnome desktop (privacy) to NOT lock the screen at idle. This is presumably working as when it awakes from sleep (by tapping keyboard) the screen is not locked and the desktop is "as left" ...
N.B. Running a "long job" at the physical display (via X, not tested on TTY) delays the sleep. Activity on ssh session (as above) does not.
The situation tricky and stupid at the same time. I've tried a lot of variants to guess why it's not working.

There are TWO
/etc/gdm3/greeter.dconf-defaults and second in
The main idea that TWO this files MUST BE THE SAME!
/etc/gdm3/greeter.dconf-defaults from ROOT and UNComment some LINE below!!!
# sleep-inactive-ac-timeout=1200 #--default sleep-inactive-ac-timeout=0 # new sleep-inactive-ac-type='blank' # - As above but when on battery sleep-inactive-battery-timeout=0 sleep-inactive-battery-type='blank'
Just SAVE IT and copy to PATH
Note that these files MUST BE THE SAME!
P.S I think it's a bug because,
after you edit
dpkg-reconfigure gdm3 --doesn't work proper (Should change
