[SOLVED] 100% CPU usage after update

abhinavg90 · 2009-04-05 07:55:23

I am experiencing an annoying problem

I updated my system after quite some time today and
now the CPU is stuck at 100% usage. The system is a
dual core and according to system monitor the 100%
usages alternates sometimes but theres always one
CPU at 100%. And in the process list, no process is
using that 100%.

I was using catalyst earlier, but due to the latest update,
it doesnt support my card anymore so I installed the open
source ati driver. Now this is when I first noticed 100% usage
as the graphics were lagging, though it was probably there
since before this because it turned out I installed the wrong
driver. I installed the correct ATI driver, theres no lagging,
its working perfectly but the 100% CPU usage persists.

I thought it has something to do with the open source driver
so I went ahead and installed catalyst-old and catalyst-utils-old.
But the problem remained.

And the latest update broke netcfg somehow because now
wpa_supplicant gives an error when used through netcfg.
So I had switched to WICD, and now I thought it was the
problem, so I tried removing WICD and the problem was still
there. So back to WICD.

I even tried tweaking the xorg.conf for the new open source driver
as told in the wiki. But it didn't help.

And I am pretty sure this problem did not exist before today.

Heres a part of my xorg.conf

Example of cpu usage

Any ideas ?

Maybe try checking your process usage with some other app? top or htop? I have never seen a CPU pegged at 100% without a matching process to account for it.

Just checked. Its Xorg

So its probably the drivers

wonder · 2009-04-05 08:47:26

you need to update to xorg from testing. there are severals threads and a bug report about this issue.

Just enabled the testing repository. Upgraded.
Its working perfectly! Thanks!

And I guess the netcfg from testing might have fixed the wpa_supplicant error,
but I think I'll stick to wicd for now.

The method that enable the test repository is not the best way to solve the problem.

falke · 2009-04-05 14:36:37

Whats the better way?

when xsever will come in "stable" repos?

dschauer · 2009-04-05 23:29:06

An updated xorg that fixes this problem is in the the stable repos now.

Arch Linux
