Talk desktop app doesn't disable screensaver when in call

[DerDreschner]

Steps to reproduce

1. Install talk app via flatpak on Linux Mint 22.3 (in my example, other distributions are not being tested)
2. Enable screensaver and set the timer to 5 minutes (for example)
3. Open app and do a (video) call with somebody
4. Don't touch the mouse and the keyboard
5. Wait for 5 minutes (in this example)

Expected behaviour

I expect the talk app to talk to the OS to disable the screensaver (e.g., via dbus).

Actual behaviour

The talk app doesn't tell the OS to keep the screen/computer active, which means the screensaver is getting activated in a running call after 15 minutes in my particular setup. This is pretty annoying, especially as I need to type in my password after the screensaver is activated.

Was implemented in https://github.com/nextcloud/spreed/blob/cf17451cc24a7d1dad3bb9469141bafeeeb65545/src/components/CallView/useWakeLock.ts
Will check why it might not be working

[Antreesy]

Can you try this in your browser devtools -> Console (and in Talk Desktop -> right mouse click -> Toggle devtools -> Console)?

navigator.wakeLock.request('screen')
    .then(res => console.log('requested'))
    .catch(e => console.error(e))

I'd expect an error to be thrown, for this wakelock to not function

[DerDreschner]

No, it doesn't throw an error:

The response is the same when using the web app in Firefox.

But the log tells me that something's wrong with the dbus communication:

I've also run sudo dpkg-reconfigure dbus just to be sure nothings wrong there and restart. But no change at all. The /run/dbus/system_bus_socket file does exist on my host system, so, I guess it's something between the flatpak container and my system?

[DerDreschner]

@Antreesy The issue disappears when I start talk with the --socket=system-bus option found here: https://docs.flatpak.org/en/latest/sandbox-permissions.html#d-bus-access

That option isn't recommended to use due to security risks, but at least a workaround (and gives you an idea about what could be wrong).

[ShGKme]

@DerDreschner Thank you for the details, we'll check it

[ShGKme]

The dbus access was fixed in:

• build(flatpak): fix status icon render, idle detection api, screen wake lock api access #1713

We might need to check if it works properly from the frontend side, but at least the errors from the log above are resolved.
