 |

Hi,
When I login to X, at the beginning everything is fine. After a while, one of my cores (I have a dual core laptop) is constantly occupied (100%).
top reaveals:

It is X! just X. I tried closing all programs, still there.
What could it be, what can I do?
Some info:

Hey,
It took a while, until the problem reproduced. But now it happened:
pstree output:

I tried logging out, logging into KDE (X still taking 100% of one cpu) and got:

Any advise?

Did you restart the X server? | Code: | | eselect rc restart xdm |

Well, that always solves the problem for the moment. Until cpu of xorg-server goes up again ...
It also means that I have to close all applications. |

Try xrestop.
Can't guarantee it will work, but better than nothing though. Ebuild is x11-misc/xrestop |

Really always?
It's normal for akonadi to hog resources for a few minutes at startup but all smooths out again in a while.
Do you have desktop effects running? Any crazy applets?
Post your emerge --info so we can see what your box should be able to handle. |

My emerge --info is in the original post.
Restarting xorg (for example by restarting xdm/kdm) always solves the problem when it occures.
Just logging out of the WM and logging in again does not help. I also tried logging into other WMs when the problem occured, to make sure my WM (fvwm-crystal) is not part of the problem - the high cpu usage stays. |

I'm assuming it's like top, those who are at the top use more resources. Try finding out what
| Code: | | 0c00000 0 3 0 2 0 18900K 72B 18900K ? <unknown> |
is. Maybe `sudo xrestop' helps to at least getting a PID and killing it (as usual, save your work first in case the system goes haywire), or equivalent in case you don't have sudo configured.
My `xrestop' just for comparison, on a Ubuntu system:
| Code: | xrestop - Display: :0.0
Monitoring 47 clients. XErrors: 0

I am surprised no one has done the obvious and ask for some logs -- can we see:
/var/log/Xorg.0.log

Hi,
I am sorry for not answering in such a long time, but so far the problem did not occur again.
Thanks for the help so far.
If it comes back, I will come back  . |
