Bug Description

Binary package hint: icewm

The CPU usage according to 'top' is consistently at 20%-30% for the 'icewm' process, with the Xorg process also using a similar amount. This severely affects battery lifetime on my laptop, rendering icewm not usable unless connected to a power supply.

$ lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04
$ apt-cache policy icewm
icewm:
  Installed: 1.2.37-1ubuntu1
...

Usual CPU usage for IceWM is in the 0%-2% range.

May be related to bug #307306?

After experimenting with many potential changes, including
- icewm version
- xorg version
- nvidia binary driver and nvidia kernel module versions
the only thing that fixed the problem was to run IceWM under the intrepid kernel version.

Under 2.6.27-11-generic there is no problem, but under .28 just running X and a window manager eats a full CPU and a lot of power.

I wouldn't think that it's a bug in icewm.
