I'm unable to Add Widgets to my task bar or my desktop because the list of widgets appears empty. The problem happens no matter where I Add Widgets from, the desktop or a panel, and it occurs across all workspaces.

I've tried restarting, but I'm not sure what else might help.

Any ideas how to fix it?

This is how it looks:

distro & KDE versions ?

this is a new issue, previously it worked ?

recently do an upgrade ?

Kubuntu 12.10. This is a new issue; I don't know what happened to cause it, but it was working after I upgraded from 12.4.

I think your widgets should be in /usr/lib[64]/kde/ and they would be named plasma_applet_*.so and there should be a bunch

what is:
for 64 bit ls -l /usr/lib64/kde4plasma_applet_binaryclock.so
for 32 bit ls -l /usr/lib/kde4/plasma_applet_binaryclock.so

I've got this:

ls -l /usr/lib/kde4/plasma_applet_binaryclock.so
-rw-r--r-- 1 root root 52144 01.02.2013 04:30 /usr/lib/kde4/plasma_applet_binaryclock.so

I have 64 bit kubuntu with KDE Version 4.10.

Thanks for the help!

on my system these files are executable, though I don't now if that matters on .so files - outside my knowledge base

try making it executable then see if it appears in add widgets
as root

Code: Select all

chmod uog+x /usr/lib/kde4/plasma_applet_binaryclock.so

Do you have any third party plasmoids installed as user? Look under KDEHOME/share/apps/plasma/plasmoids (KDEHOME is .kde or .kde4 depending on your distribution).

Also try to see if a new user account has the same issue.

For the record, I never fixed the problem, I just upgraded to Kubuntu 13.04 and it got resolved.

Marked as solved.
I suspect it may have been caused by certain directories existing in your home directory, which exposed a bug in Plasma.
Upgrading appears to have fixed this in this instance.
