One thing I've noticed that's funny is that sometimes when I use waypipe to launch a remote app locally it will have a random-ass icon, like a steam game or something
I use Firefox nightly and recently switched to Wayland (KDE). Ever since I switched, the taskbar often displays Firefox nightly with the regular Firefox icon, and the name Firefox instead of Firefox nightly. After reading your blog post I'm thinking that the culprit could be an incorrect StartupWMClass. But I don't get why this issue never showed on X11 then.
Yeah something isn't being matched right. Might want to look at both .desktop files and compare them. Probably be pretty obvious when you look. =)
I just checked the .desktop file for firefox nightly. It contains only firefox-nightly as its StartupWMClass. So I went ahead and also checked the window class firefox nightly is running as and found the following:
Does this mean that firefox nightly is using both, the firefox and the firefox-nightly window classes?
Yep it has both applied. What are the actual .desktop file names?
The desktop files are named firefox.desktop and firefox-nightly.desktop, both in /usr/share/applications.
EDIT: For completeness, I also checked the window classes of the regular firefox:
It can be observed that it uses only the window class firefox, but twice?
Yeah in your case the best fix is probably REMOVING StartupWMClass from those launchers if it is present. Then it will only match the app id on the .desktop file name.
Hmm, but I thought the StartupWMClasses in the desktop files are correct? I thought the issue is that firefox-nightly uses the firefox class in addition to the firefox-nightly class
StartupWMClass is NOT needed if the .desktop file is named correctly.
I see, so I could remove it, but wouldn't I still see the same behavior, since firefox nightly apparently also uses the firefox window class?
why's there an arch linux app in that image
I actually use that logo for my app menu.
yea fair enough, kinda makes sense.
I wrote up
I don't think you did.
You can think whatever you want.
StartupWMClass=
I've never seen this line in a .desktop. What is it for?
This is literally what the article was created to explain. Just one more click, my guy, you’re almost there.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
