Plank does not support Wayland.

Well, workaround is to start gnome on xorg instead.

Still, this will is blocking on wayland.

I can confirm the problem after upgrading from Fedora 24 to 25.

Still happening as of today.

Is there a way to have plank start with xwayland, so minimal changes would be required, if any, to have plank keep on working on wayland using X?

I can confirm that in version 0.11.4 it's still not working. It worked when I installed it, but after some reboots stopped with the same error explained in the bug report.

archlinux
gnome 3.24.1

I also face the same problem after activate bumblebee on my laptop

Hello,

I don't mean to be pushy, but this bug is more than 2 years and a half old now and Wayland support is still missing on Plank.
Is there any plan to add it?

Thank you

Regards

Any updates yet?

Any updates in April? Ubuntu 21.04 will run on Wayland. Does it mean we won't be able to use Plank anymore?

Just indicating that this is still an issue on PopOS (based on Ubuntu 22.04). Launch Plank and we're clearly told with an error message that Wayland support isn't there and Plank will terminate.

For now Xorg is the way to go. I'd like to move to Wayland and let XWayland handle Plank so for now I'll stay with Xorg.

Falling back to XOrg is no longer a viable solution as you cannot do that without sacrificing functionality such as touch pad gestures etc...

Confirmed still an issue on Ubuntu Lunar (23.04) development version as of Dec 15 2022.
