High CPU load after upgrade

[Jeje]

After upgrading to ubuntu 9.04 from 8.10 the CPU load stays at around 60% in the system monitor & the fan is quite noisy. I can't identify the responsible process - there is no process with excessive CPU usage in the process list!?

Hi Jeje,


I have exaclty the same problem and in fact your process dump looks exacly like mine CPU always around 36%. Nothing appears to be causing it. It is a X11 or GDM problem though because when you close gdm it goes back to normal (CPU 2%).

I upgdraded from 8.10 to 9.04 which went 98%, tracker had some problems which I have now turned off.

Hi gain Jeje and other too high CPU Xorg ers.

After trying to close down a few services to perhaps see what if anything I was using was overusing Xorg I eventually stopped vino-server which in itself was not using a lot of the CPU. However straight after I killed it bang my CPU usage went down 1%-4%. Vino-server is part of the gnome remote desktop. The system still did feel a little highly strung with the CPU happy to increase with compiz usage which I have somewhat turned of some it's features. Note before I upgraded all worked fine under 8.10. However 9.04 is now a how lot better as expected. I hope this may help

Hi fjpos

Thanks for that tip! Issueing a 'killall vino-server' does the job. Even though it is respawn straight away the CPU load stays low?!
