[SOLVED] Xfdesktop not starting

Hello, my xfdesktop is failing to start, given the error that it gives, it seems an issue with the last update of the package glycin, version 2.2.3-1.

$ xfdesktop

thread '<unnamed>' (12674) panicked at glycin-core/src/gobject/pixel_density.rs:126:14:

For now I have "resolved" by rolling back to the previous version: https://archive.archlinux.org/packages/ … kg.tar.zst
I don't know if this is the correct place where report this issue, if not, let me know,

thanks!

Re: [SOLVED] Xfdesktop not starting

Slightly different backtrace, https://gitlab.gnome.org/GNOME/glycin/-/work_items/342

Starting xfdesktop by hand after login, with the same wallpaper, works fine. The crash only happens in the first few seconds of the session, so it looks like a startup race rather than a problem with the image itself.

True?

Re: [SOLVED] Xfdesktop not starting

I have a very similar problem with xfdesktop not starting correctly : after login desktop icon blink and then disapear. I got a black background on the desktop.

Launching manually xfdesktop produce a similar trace as shown in post #1.

Long story:
After upgrading this morning, lightdm start working. I restore it by removeing the package and re-install it. Then once I can login the deskop show a fully black background instead of the picture used. The desktop icon blink and then disapear.

After seeing the first post, I downgrade glycin to version 2.2.2 and this fix the xfdesktop problem (desktop icons and image are back).

Re: [SOLVED] Xfdesktop not starting

Hi Guzzista, I got the same issue.
Rolling back glycin package, solves the problem for me.

How did you find out that glycin is the problem?
When I start xfdesktop, i missing a stacktrace.

Re: [SOLVED] Xfdesktop not starting

Hello @xafnir, I discovered it was glycin by looking at the stacktrace, it is printed in the terminal when I execute xfdekstop (the one I pasted in my first post).

The issue itself seems to appear only when the background is a Jpeg image (but only some of them).

And since glycin is also used by Ristretto image viewer, that also crashes when opening the same jpegs.

I have created an account on Gitlab to report the issue, but now I noticed someone reported it better than me: https://gitlab.gnome.org/GNOME/glycin/-/work_items/347

Re: [SOLVED] Xfdesktop not starting

\o/
It's also closed/fixed upstream.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
