xfce4-taskmanager doesn't show cpu percentages

[A.Kromic]

Binary package hint: xfce4-taskmanager

CPU percentages of all processes stay at 0%.

ProblemType: Bug
Architecture: amd64
DistroRelease: Ubuntu 8.10
ExecutablePath: /usr/bin/xfce4-taskmanager
Package: xfce4-taskmanager 0.4.0-1
SourcePackage: xfce4-taskmanager
Uname: Linux 2.6.27-7-generic x86_64

Thanks for taking the time to report this bug. I installed xfce4-taskmanager and compared the cpu usage to that shown in Applications -> System -> Task Monitor. The CPU shows about the same in both, but task-monitor shows the action of the application. Since most apps are ¨Sleeping¨, the CPU usage is 0. With both applications, if I move a mouse or move a window, at least one task will show an increase in CPU percentage. All applications will show 0 for CPU% when they are not in use.

Did you try on hardy or intrepid? It seems to works on hardy, but is
broken on intrepid (intrepid ships the 0.4.0 version which is a partial
rewrite).

Someone should check the changes in the refresh_task_list() function
in src/functions.c between intrepid's 0.4.0 and hardy's 0.3.2 versions,
or report the bug upstream.

My comments are using Intrepid 8.10 with all updates as of 2008-12-06. Are both task-manager and Task Monitor then broken since both show the same things in CPU% ? I compared them side by side.

What's your cpu? single or multi-core?
I have a multi-core, so does the bug reporter (by looking at the
attached ProcStatus.txt). The bug is probably here.

Thank you. I have an AMD Athlon 64 3500+ 2.20GHz, apparently single-core. Can I confirm this then?

Then this issue matches this entry (changelog from the 0.4.1 version):
  * Fix cast which makes the CPU usage per process worky for multi-cores

So this is already fixed upstream and uploaded in jaunty
(0.4.1-0ubuntu1).

To get the fix in intrepid, someone will have to do a SRU or file a
backport request.

Thanks for your help!
