Title:
CPU increase when using lxtask + 11.04 gtk theme
To manage
I have installed the package from -proposed and can confirm that it
fixes the bug. However, on my system the LxDesign theme (which was
mentioned in comment 5 to test for) didn't have an animated progress bar
in the stable version, so I used Lubuntu-default theme for the test:
The Lubuntu-default
I am using Lubuntu Oneiric alpha 1 and the problem of 100% CPU usage
persists.
After boot, in the process list of the htop command, there is no process
consuming more than 3 %. However, the total usage reaches 100 %. Please
tell me what should I try next.

This is not the same bug. On Oneiric, lxtask display 100 % of CPU usage
all the time, even if there is no activity.

So the theme doesn't need to be changed again. Are you using GTK2 or
GTK3 applications when this happens? Anyway, this was solved and so
thread marked as that.

Thanks for the reply.
In the short term, I'll disable the animation for Natty and Oneiric. We will
re-evaluate this later in Oneiric cycle. Also, with the switch to GTK3, maybe
progress will be made about this issue.
** Also affects: lubuntu-artwork (Ubuntu Natty)
Importance: Undecided
I don't really how to measure this. But I've tested (with two terminals)
that my system uses near 2% CPU when iddle, and lxtask adds up to 8%
more. But I think it's normal. I can't reproduce your settings.

No, the problem is not with lxtask. Try to switch to LxDesign theme and
watch your CPU usage.
Anyway, I think I found the problem. If I remove line 131 :
animation = TRUE
my CPU usage is back to normal, like the previous gtk theme. Except the
animation on the progress bar, I don't know
I think this only affect progress bars. But I've noticed Fedora 15 and
16 have a problem with this. Murrine is being compiled bad with this
option (maybe a bug in Murrine). We need to test it with other Murrine
themes, like Elementary. If problem persist we'll have to take the
decision about
It's not a problem of using a taskmanager, because I used it in both
tests :
With lxdesign + taskmanager running : 60 % CPU usage
With ozone + taskmanager running : 80 ~ 90 % CPU usage
You can try by running lxtask, and switching the gtk theme from one to
the other. You will see the change in
I don't really know (for now). But using a task / process manager
increases the CPU usage a lot, because of the continuous scanning of
threads in RAM. Try gnome-system-monitor and you'll see your CPU usage
increasing up to 100%. If problem persists without using monitors the
it's another problem.
