[Bug] Segfault on running dev panel manager branch on Magpie

[JoshStrobl]

Description

When running budgie-desktop branch 473-implement-wayland-support-in-panel-manager, with @Conan-Kudo's budgie-wayland-session file for magpie, upon login through SDDM it will black screen and kick me back to SDDM.

I am not 100% convinced that the budgie-wm code to effectively no-op and clean exit on detecting Wayland works under magpie v1 (under kwin, libxfce4windowing does detect the windowing system as Wayland), so may be worth taking a look at too, but would be good to start getting everything else to run.

Ties into #13 with missing Wayland protocol support too.

Magpie version

1.0~git20240413.f0fcf8e-1

Operating System

Fedora 40

Steps to reproduce the issue

1. Build 473-implement-wayland-support-in-panel-manager branch of budgie-desktop
2. Build make-failwhale-noop branch of budgie-session
3. Install budgie-wayland-session bits, just do not install sddm files until layer-shell support is in magpie or SDDM will not work.
4. Install sddm, kwin. I'd recommend also kscreen + plasma-systemsettings (or respective package name) for monitor configuration
5. Launch Budgie Desktop via the magpie session. Notice it no worky.

Actual result

Expected result

A very broken but visible Budgie.

Additional information

No response

[serebit]

Can you coredumpctl debug the segfault and get a backtrace from gdb? From what you've showed, the segfault looks to be happening somewhere within xwayland_surface_set_geometry, so I do have a starting point to debug from.

[serebit]

Never mind, saw the problem almost immediately. Try latest v1 and see if that works. Commit 9af5081.

[Conan-Kudo]

Updated builds have been published in COPR.

[JoshStrobl]

Progress! I saw budgie-panel for a second before getting kicked back to SDDM.

If you have any recommendations on the best way to debug it while under a Wayland compositor that'd be appreciated as using coredump debug PID just shows a black screen and reports the following:

unable to lock lockfile /run/user/1000/wayland-0.lock, maybe another compositor is running

Attached is the output from journalctl: magpie-wm-9af5081-journalctl.log

Linked via Proton Drive is the output file of coredumpctl dump of the process. Too large to share via GitHub.

[serebit]

It seems to be segfaulting within Server::focus_view based on the journald log, though I can't see any obvious place where a segfault would be happening. I also can't check the coredump you linked directly, as I'm not on Fedora. Does running coredumpctl debug on the process that you dumped give a line number?

[JoshStrobl]

Here's the bt. I think my next step will be making sure there aren't any applications set to autostart that could be triggering the behavior.
