Hello.

Recently some icons refuse to appear in the system tray.

The ones that still appear changed from colored to grey.

KDE version is 4.6.5-3 from debian unstable.

Two of the missing ones are from UIM and amule-gui.

An image:





Edit: The value of the visibility field doesn't seems to matter.

Edit2: Well... Looking for help... Please, thanks and so...

It looks like they're still there, just not visible. Is that correct? You can try to click to the left of the monochrome icons.

can you create a new user and see if that user experiences this?

did you recently update? change theme, colors or icons?

is this missing system tray icons limited to non-kde apps?

try running

Code: Select all

kbuildsycoca4 --noincremental

the "kbuildsycoca4" thing didn't help, but it works with a new user.

I can rename my .kde dir and reconfigure some things... Too much years, too much updates... Maybe it's time to clean it.

Thanks.

removing .kde and starting fresh is a bit drastic

alternatives to try:
- clear your cache

Code: Select all

 kquitapp plasma-desktop
 sleep 20s/
 rm -rf /var/tmp/kdecache-your_user_name
 plasma-desktop &

- remove system tray widget and re-add it
- remove panel and add new default one
- move plasma rc files and start with defaults

Code: Select all

kquitapp plasma-desktop
 sleep 20s
 mkdir -p $HOME/plasma-config/
 mv $(kde4-config --localprefix)/share/config/plasma-desktop* $HOME/plasma-config/
 plasma-desktop &

- move the ~/.kwin* files

Thanks a lot

I had the same problem for quite a while.
The problem was this entry in plasma-desktop-appletrc:

[Containments][12]
ActionPluginsSource=Global
activity=New Activity
activityId=No such object path '/ActivityManager/Activities'
desktop=-1
formfactor=2
geometry=0,-44,1864,38
immutability=1
lastDesktop=-1
lastScreen=0
location=3
plugin=panel
screen=-1
zvalue=0

When I removed the entry, the problem was solved.
Maybe the activityId was the problem.

An entry which has "activityId=No such object path '/ActivityManager/Activities'" in it is totally invalid.
Removing it, without Plasma Desktop running is the correct course of action in this case.

Did you generate this under KDE 4.10? If so, it may be worth a bug report.
