[Karmic] xorg-server has high cpu utilization - system slow and unresponsive

[pdaemon]

Hi,

Since using update-manager latest packages xorg-server seems to be taking up a high proporti. This is causing the mouse to freeze each time something is clicked and the system is very slow. Also it is very slow to get to the login screen and then log in as well.

Below is some info:

Hi,

I have just upgrade to Karmic Alpha 5, after running Jaunty for a while and I'm still hitting the same problem. Startup is taking around 10 mins. Once Desktop is showing then another 5 mins to be able to do any kind of work as mouse is un-movable.

Please tell me what info I can grab from my system in order to fix this bug.

Running under Jaunty was fast, so it's seems to be software related!

Regards
pdaemon

I have the same bug, xorg is taking 50 percent cpu. (dual core cpu)

I'm using the nvidia closed driver.

[Alejandro Del Rincón (alexsp92)]

hello i also have this problem...
a temporal solution is restarting the Xserver:

sudo /etc/init.d/gdm restart
sudo /etc/init.d/kdm restart

i use the nvidia drivers

[Vinicius Seixas (vipseixas)]

Same problem here with latest Karmic updates and Intel Mobile GM965/GL960 video card (Dell Vostro 1310 notebook).

$ uname -a
Linux dollhouse 2.6.31-11-generic #38-Ubuntu SMP Fri Oct 2 11:55:55 UTC 2009 i686 GNU/Linux

$ lsb_release -d
Description: Ubuntu karmic (development branch)

Restarting gdm resolved the problem.

[Martin Albisetti (beuno)]

I wonder if this is the same as bug 439138?

[pdaemon (philipp-burath)]

Looks like the same bug! I don't seem to have this problem anymore after the latest updates.

[Alejandro Del Rincón (alexsp92)]

Its seems that is fixed...
please try to update and tell more :)

[pritam ghanghas (pritam-ghanghas)]

I still have the problem with all the latest updates installed. I had upgraded from jaunty few days back. I have just finished rebooting my system after a full update. My xorg version as reported by dpkg is "1:7.4+3ubuntu5". Cpu usage goes as high as 35% this dual core 1.6Ghz system.

[manolo (mac-man2005)]

I upgraded to karmic a couple of days ago, since Synaptic announced that it was possible to upgrade to 9.10

My system is unusable because of this bug.

1) What's the actual situation about this bug?
2) Which informations can I provide in order to contribute to the solution?

Thanks
