System is unstable after upgrade

[Frdric_Meyer]

Hello,

I've just upgraded to 13.04. With 12.10 all is ok, the system is nice. But with 13.04 all is slow, my Intel i3 often goes over 80%, many applications crashes when i do some action (button click, combo selection, ...). These are applications that i used today and that have often been crashed:
- Google Chrome
- Firefox
- Eclipse (Indigo, and Kepler)
- VLC
- Skype
- Kdevelop
- Gimp
- Bouml
- MySQL Workbench

What's happened ? Kernel 3.8 has problems ? How resolve that ?

Thanks.

More harware info - ram, video, etc.

Also run either 'top' from terminal or gui System Monitor, and watch what is consuming you cpu usage.

'top' doesn't give any information, all is slow, several aplications consuming cpu usage.

I don't think that killing any processes which overload CPU is the solution. The problem is elsewhere. I've just upgraded and rebooted, that's all i done. The system had great performances (really great) with 12.10 but now i can't use my computer as well as 12.10. The problem may be kernel 3.8 cause before upgrading the kernel 3.2 was fine i didn't need change any driver or otherwise, all worked.

All my applications are slow. With 12.10 all is fine. No modification done on system after upgrade.

What processes are hogging all the resources?

How does 13.04 work in a live boot?

[Frdric_Meyer]

I've found the solution.

In fact, the problem was Graphite module for Pango. It make crashes application (all that use GTK for example) with a segmentation fault sometimes.
I've removed ubuntu package: "pango-graphite".

Now, applications don't crash and my system works fast.
