When calling 'systemctl suspend' in the terminal, it shows what app and why it's blocking

Comment 2 Nate Graham 2025-04-02 21:14:30 UTC

That's not quite how this works; when an app blocks sleep and screen locking, it only blocks *automatic* sleep and screen locking. You should be able to manually initiate these yourself.

I gather that's not happening? If you prevent the apps from blocking sleep and screen locking using the "Unblock" button on the Power and Battery widget, are you able to manually initiate sleep or screen locking? Or does that continue to fail?

Comment 3 Répási Dávid 2025-04-03 11:15:18 UTC

So, I tried with other torrent clients as well, but this only happens with qbittorrent for me. 
Options enabled: Preferences -> Behaviour -> Power Management -> both options

When using the 'Unblock' feature - either option, nothing happens, just the silent fail.

Comment 4 Nate Graham 2025-04-03 15:37:52 UTC

Only when QBitTorrent blocks sleep, and not for any other apps? That's very strange.

FWIW, I can't reproduce the issue; when I install QbitTorrent, use those settings, and start a torrent, I can manually put the system to sleep as expected.

Can you reproduce this issue in a new clean user account?

Comment 5 Répási Dávid 2025-04-03 20:29:44 UTC

It works fine on a different  machine with a clean install.

Comment 6 Nate Graham 2025-04-04 12:27:13 UTC

Thanks. How about in a new clean user account on the same machine?

Comment 7 Répási Dávid 2025-04-07 08:29:16 UTC

Works fine on a newly created user account as well. Could be some update borked a config file in a past update.

Comment 8 Nate Graham 2025-04-08 17:02:18 UTC

Could be indeed. If you could try to figure out what configuration is causing the issue, that would be amazing.
