GNOME Bugzilla – Bug 767985
System immediately suspends after log-out / lock on tablet device
Last modified: 2019-03-20 11:35:32 UTC
On my Surface 3 tablet, when logging out the user, the device immediately suspends. I believe this is due to the feature that will suspend the system when the display is made blank on tablet devices. What I would expect in either case is for the lock or login screen to be displayed, and then perhaps after a short idle timeout the screen would be blanked and suspending may occur - basically user activity could prevent or postpone the automatic suspend. I feel this is important to adjust because as a user, when I perform an action, I do not want my device to immediately suspend while I am interacting with it - I could be trying to switch users for example. It doesn't really matter the use case, the device should not be told to go to sleep while it is in use - and logging out or locking the screen is not a reliable indicator that the device is not being used.
Trying adding CHASSIS=laptop to /etc/machine-info and let me know whether that fixes the problem.
After setting CHASSIS=laptop, the machine no longer immediately suspends when logging out, locking the tablet, or selecting "switch users" from the menu.
There's probably a bug around that section of the code then :/
It doesn't suspend when logging out on my Surface 3.
I can't seem to reproduce on log-out either anymore, but the switch user / lock case still seems affected.
