How make the window display the App Icon instead of the default Icon? #133
-
|
I'm using I'm running an single-app container via a custom sh file that exec an AppImage. I checked the AppImage file that contains a However, after the app runs, the default icon is displayed in the upper left corner of the window instead of the app icon. Does it require the app to adapt to WayLand in some way, or can I somehow make the window display the app icon?
The default icon is like the "st" icon in the image below. |

Your app is not conforming to something and is likely running under Xwayland. You said it was an appimage so that might explain part of it. Labwc should work like other DEs, I run wayland on my desktop and all kinds of apps have the wayland icon fallback in the window decoration. |

I think it's unrealistic to expect all apps to quickly adapt to Wayland, whether it's Xwayland or other compatibility issues. Since the app can be auto fallback using Xwayland, why can't the app icon? Fallback to the default icon is really annoying. |

Yes, it is, thank you. The app icons are obviously present, but they cannot be found in labwc/Wayland mode. |

Wayland is used because it is the only way to do a all this in user space (specifically zero copy GPU support). I have posted detailed write ups on our blog X11 just can't do this in user space and I even patched xvfb to support GPUs via glamour, but you still have to do CPU readbacks and layer the pixmaps. https://www.linuxserver.io/blog/webtop-4-1-x11-is-dead-and-what-is-selkies-anyway https://www.linuxserver.io/blog/webtop-4-0-wayland-is-here-engage-the-reality-engine For containerized desktop applications this stack is much more friendly and performant that how we used to hack X11 in, but you are absolutely free to still use X11 it will just not see anymore development for accelerated environments. |

Yes, I've read both articles, and they're very well written. That's why I tried using Wayland mode, but this is the issue I'm currently encountering - the app icon isn't displaying. |

@thelamer A little question. I know that Wayland's main advantages are GPU and Zero Copy, but if there is no GPU and it is rendered through CPU and Pixman, is there any advantage over X11 mode? |

Are you talking about the selkies-desktop project? That shows desktop icons in the ~/Desktop folder please take a second to read this https://github.com/selkies-project/selkies-desktop. Even without a GPU and just in general the wayland side is the one seeing active development. |

Yes, I figured that out, but I don't understand why the running app in taskbar doesn't show the icon.
Yes, selkies-desktop is an example. I'm running headless Linux, so there's no GPU there, but in Wayland mode I still feel like some aspects are much smoother than X11, and I'll continue to use Wayland. Thank you for your great work and reply! ❤️ |

By manually adding the
/usr/share/applications/org.app.desktopfile, I successfully got thewindow iconto display correctly and the app item to appear in theStart Menu.However, the running app in the
taskbarstill doesn't show an icon, and there's nodesktop iconeither. I don't know what's going on, maybe there are other things that need to be set.All of the above are tested in Selkies Desktop.
