A few weeks ago, icons for various applications disappeared.

Application Dashboard: https://i.imgur.com/fg4VuxS.png

Application Launcher: https://i.imgur.com/oQrPrBY.png – https://i.imgur.com/ZHDwGgI.png

– the Task Manager view of icons is fine.

Any ideas?

I already tried obvious things such as clearing caches, and preferring something other than Breeze for icons.

Seeking Firefox finds:

• Firefox with an icon
• Firefox Web Browser without an icon:

I can't guess/recall the origins of the userapp- .desktop files.

Environment: FreeBSD 14.0-CURRENT.

Code: Select all

% cat ~/.local/share/applications/userapp-Firefox-96SHUZ.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
NoDisplay=true
Exec=/usr/local/lib/firefox/firefox %u
Name=Firefox
Comment=Custom definition for Firefox
% rm ~/.local/share/applications/userapp-Firefox-96SHUZ.desktop
% rm /usr/home/grahamperrin/.local/share/applications/userapp-Thunderbird*
% rm /usr/home/grahamperrin/.local/share/applications/userapp-Waterfox*
% rm /usr/home/grahamperrin/.local/share/applications/userapp-New\ Moon-BVJBZZ.desktop

I imagined that the bug involved Application Dashboard and Application Launcher.

Now I see that icons are similarly missing in an LXQt Desktop view of things, so I'm shifting discussion to a FreeBSD area:

Icons missing for GTK-Mixer, Firefox, Thunderbird and more | The FreeBSD Forums

Workaround for Firefox on FreeBSD, in brief:

Code: Select all

ln -s /usr/local/lib/firefox/browser/chrome/icons/default/default48.png /usr/local/share/icons/hicolor/48x48/apps/firefox.png

Context: https://forums.freebsd.org/posts/555682

The same workaround for Thunderbird, although I can not understand why there was no killing in response to pkill:

Code: Select all

root@mowa219-gjp4-8570p-freebsd:~ # ln -s /usr/local/lib/thunderbird/chrome/icons/default/default48.png /usr/local/share/icons/hicolor/48x48/apps/thunderbird.png
root@mowa219-gjp4-8570p-freebsd:~ # exit
logout
% pkill plasmashell && plasmashell
% echo $SHELL
/bin/tcsh
% whoami
grahamperrin
%

Where the pkill line had no effect in Konsole, it was subsequently effective in KRunner.
