cinnamon: Brightness OSD doesn't show on primary display

[mantuoliveira]

Describe the bug

The screen brightness level is always shown on the external monitor even though the notebook screen is set as the primary display.

To Reproduce Steps to reproduce the behavior:

1. Connect an external monitor (In this pc, this will only work if the nvidia card is selected)
2. Make sure the notebook screen is the primary display
3. Change the screen brightness using the Fn keys

Expected behavior

The screen brightness level should be shown on the notebook screen.

Additional context

[clefebvre]

Just noticed we show sound OSD on all monitors.

[JosephMcc]

Prior to Cinnamon 5.4 the sound OSD was shown on all monitors and the brightness OSD was only supposed to show on the monitor where the brightness change was actually happening.

[mtwebster]

It still should only be the monitor being changed.

Does this continue happening after you've restarted cinnamon? (or logged out and back in)

Can you run this while the problem is manifesting:

cinnamon-dbus-command GetMonitors

and paste the output.

Thanks

ah ok sorry, I wasn't aware this could be set per monitor.

[mantuoliveira]

Restarting cinnamon has no effect, but rebooting the pc sometimes fixes/causes the issue. I will try to find a consistent way to reproduce it. Meanwhile, this is the output of the command you asked for:

Parsed: GetMonitors(format_string='()', args=[])

Returned: ([1, 0],)

[mantuoliveira]

I've found a way in which I can reproduce this all the time.

I have a hybrid notebook (amd and nvidia). When selecting "Power Saving Mode" I can't see anything on the external monitor. Selecting "Nvidia on-demand" results on both displays working and correct brightness OSD placement. However, selecting "Performance Mode" and rebooting the pc will always place the brightness OSD on the external monitor.

Not sure if this is intentional behavior or a another bug, but to go from NVIDIA only to NVIDIA on demand, one must use the "NVIDIA settings". The option is missing from the applet.

[mtwebster]

That's a bug, it'll be fixed in the next update for that applet.

It seems like the system is mis-identifying which is the built-in monitor when you're in nvidia mode. Does the brightness adjustmant always work, and always the laptop monitor, regardless of prime mode, or where the osd shows up?

Can you provide the output to xrandr --verbose in both performance and on-demand mode? (Use dpaste.org or something because the output will be long).

[mantuoliveira]

on demand performance mode

It works in both cases. No matter where the OSD is shown the laptop screen brightness is correctly adjusted.
