Ubuntu Studio 16.04 LTS, 4.4.0-22-lowlatency, xfce4 4.12

I suggest you report a bug

Manfred Hampl (m-hampl) said : #2

I assume that "panel-6-indicat" is not the full process name, but cut off in the display of the top command. Perhaps it is "panel-6-indicator".

What is the output of the command
ps ax | grep panel

I do not find any Ubuntu package that provides an executable with a name containing "panel-6-indicat", so there is the question whether you maybe have installed that program from some foreign source?

P.S. I use xfce4 + compiz

This question is for xfce4-indicator-plugin package. Is there way to move it where?

Manfred Hampl (m-hampl) said : #5

The command line executed apparently is
/usr/lib/x86_64-linux-gnu/xfce4/panel/wrapper-2.0 /usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libindicator-plugin.so

The xfce4/panel/wrapper-2.0 binary is setting the process name during execution, I assume to the value "panel-6-indicato" (16 characters).

You might try re-installing the involved packages (xfce4-panel and xfce4-indicator-plugin).

"...killing the panel-6-indicat doesn't help..."
You might try killing that process via its (assumed) full name "panel-6-indicato" or using the process ID that you got via ps ax.

Romik Forest (forest-software) said : #6

I was killing it by pid shown by top. The Indicators are hidden from the panel for a while and then restarted.
Reinstalling xfce4-panel and xfce4-indicator-plugin doesn't help. I have 18-28% CPU usage by indicators always (and immediately after rebooting).

"...This question is for xfce4-indicator-plugin package. Is there way to move it where?..."
Open https://answers.launchpad.net/ubuntu/+source/xfce4/+question/293837/+edit
and change the package to xfce4-indicator-plugin

I do not see much what we can for you in the question area, I suggest that you create a bug report (if you have not yet done so) and let the developers have a look at your problem.

Can you help with this problem?
