Re: [libreoffice-users] Libreoffice, task manager bar and the running application icon

Alex,

Sorry I didn't get back to you sooner. I was attending a conference the 
last 3 days.

There is a manpage for gtk-update-icon-cache which explains what it does 
and what to expect. Here is a snippet from that manpage:

-----

gtk-update-icon-cache creates mmapable cache files for icon themes.

       It expects to be given the PATH to a icon theme directory 
containing an index.theme, e.g.
       /usr/share/icons/hicolor, and writes a icon-theme.cache 
containing cached information about the icons in
       the directory tree below the given directory.

       GTK+ can use the cache files created by gtk-update-icon-cache to 
avoid a lot of system call and disk
       seek overhead when the application starts. Since the format of 
the cache files allows them to be mmaped
       shared between multiple applications, the overall memory 
consumption is reduced as well.
-----

I checked the LibreOffice 5.3 package file in /var/log/packages, which 
shows LibreOffice was installed into /opt, but the icons are installed 
into /usr/share/icons/gnome and /usr/share/icons/hicolor and 
/usr/share/icons/locolor . The script I gave you caches all three.

I think the problem you are experiencing may be caused by the old cache 
not reflecting the updated icons after you installed the LibreOffice 
update, thus xfce or kde fail to load the icon(s) and they will display 
the default icon. Running the script I suggested will re-sync the icon 
cache to your new icons.

No, I don't think you need to reboot after using the script. That is a 
windows-ism.

BTW: To keep the record straight, the icon-theme.cache file is not a 
script as you called it. So, you cannot execute it. In fact, it is not 
human-readable.

HTH.
