Position has not updated after display resolution change

[Plutoz]

Hi everyone,

I have some issues with the bottom position of Plank.
When I plug an external monitor with higher max resolution to my laptop and I apply it as single display, Plank stucks at the position of previous monitor's resolution instead of applying of the new bottom position (see attached screenshot).

After a re-login, Plank uses the expected bottom position.

After this I've also tried to switch to a lower resolution and in this case, Plank did not show at all (I guess, it stayed at the original position outside the new resolution).

OS: Ubuntu Budgie 21.04 (Kernel: Linux 5.11.0-18-generic)
Gnome version: 3.38.5
Video card & driver: Geforce GTX 950M (with Nvvidia driver: 460.80)
Plank version: 0.11.89

This issue was not present in a previous version was bundled with Ubuntu Budgie 20.10 but happened immediately after version upgrade.

Thanks,
Plutoz

I was just about to create this issue ticket as well. I have a working work around - but I believe if we used the same type of code or logic used in xeventbind to detect resolution changes then we could reasonably update Plank to relocate itself without needing to restart the entire program.

For now though users can implement this workaround that I worked out using xeventbind.

This patch does not actually working like it should, at least not for me. It needs to be revisited and then tested on Ubuntu Budgie 21.04 imo and Ubuntu in general with x11. Assuming this was only tested on Debian.

I can confirm this bug after upgrading from Ubuntu 20.04 to 22.04.
If I change the resolution (Or login from SDDM with lower resolution),
the dock keeps the position of the lower resolution.
For the autostart on login I've set a timeout of 5s, so plank is able to recognize the right resolution and starts with the right position. But this wouldn't work if i start from suspend mode (as plank is already running.)

Plank still needs to redefine the position if the resolution changes.

This has been resolved by the upstream pull request https://github.com/ricotz/plank/pull/6

So the plank package needs to refresh the patch 0001_changed-plank-positioning-according-to-workarea.patch

Working on this.
