Hi manolo,
This bug was reported a while ago and there hasn't been any activity in it
recently. We were wondering if this is still an issue? Can you try with the
latest development release of Ubuntu? ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .
If it remains
It doesn't affect me anymore. The problem is that upgrading to 9.10 didn't
actually upgraded the kernel.
Something strange happened: the kernel was not marked as installed all in
Synaptic or it was installed but not the one coming up with Karnic.
I solved it installed the latest kernel at that
I have the same behavior with:

Linux sshishov 2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 01:26:53 UTC 2010

I had this issue with older kernels too. What may be the reason of this
annoying bug?
I don't have any slowness on my laptop (Lenovo Y550)
I just did a clean network install (keeping old /home) of 9.10.
1 CPU at 100% from boot. Logging out and in again puts both CPUs at

Ok, so the no menu.lst is a red herring, we are using grub2 now (GNU
GRUB 1.97~beta4).
My CPU problem seems to be unrelated then.

Yep, unrelated, and now fixed. Caused by legacy custom startup script
that did not have the necessary module in kernel anymore, or something.

Wow, weird that this would cause high X CPU, but stranger things have
happened. Since modifying grub solved it, it sounds like this may be
more of a kernel issue than X so I'm reassigning.

Hi Brice.
Thanks for your interest. Actually I had grub2 installed before upgrading to
9.10.
On the other hand, as you notice, it's very strange that modifying grub.cfg
made the new kernel appear as installed reading the list of programs offered
by Synaptic. Actually, before pointing my
Hi,
In my case, I don't have grub2 installed, I have grub (called now grub
legacy), so couldn't be a grub2 bug.
For me, it seems an upgrade problem. Due to some error during the
upgrade, the process didn't updated the grub configuration (in my case,
the menu.lst file). And the error may have to
Hi Ride.
I've already been upgrading a desktop computer (AMD 64 bit) from 9.04 to
9.10 and I had no upgrading problem.
No grub2 problem, no grub legacy problem, no general net-upgrading
problem.
Hardware problem? Uhm... are me and you the only ones having such a
buggy kind of hardware?

I had this same problem after upgrading from 9.04 to 9.10 caused by the
kernel not being upgraded, and the discussion here got me around this
problem. Thanks!
I think in general the upgrade has bugs caused by untested (special)
cases. I still have other problems (see
Hi,
I attach some logs too.
This is a real nightmare, even a silly thing like get and attach the
logs took me an hour or so. You could see in the top log that my
problem is huge, with cpu peaks arriving to 95% and up.
I hope this could help. Thanks in advance.
Bye

The xorg logs for both Manolo and Ride show you are using the old Jaunty kernel
(2.6.28) and drm is not properly working. Please make sure you boot with the
new Karmic kernel (2.6.31) and see if that solves the problem.
If the karmic kernel still has this problem, please attach xorg.0.log and

Hi,
I have the same problem with an Acer Aspire 5810T laptop (with
integrated Intel graphics card). It worked fine with 9.04, but just
after upgrading to 9.10 the Xorg cpu problem appeared.
- Logging out and logging in again doesn't have any effect
- Killing Xorg process doesn't have any effect

Same here, although I use Kubuntu.
I'm not sure if it's an Xorg bug or plasma bug, because top says:
