[Bug 448678] Re: Karmic: Thunderbird&Xorg hog CPU

[Christoph]

I confirm that jooloop's fix (comment #12) works for me.

If you want to test it, here are the steps I had to take (from Ubuntu 9.10, there is no more xorg.conf file by default*; you have to create it first):
- log in on an old-fashioned terminal (alt-F1, user, password)
- stop X: $ sudo /etc/init.d/gdm stop
- create a xorg.conf file: $ sudo Xorg -configure (it will be saved in your home directory)
- open the new xorg.conf.new file (I did it in the GUI :-)
- look for the graphics device section
- add the MigrationHeuristic and the AccelMethod lines
- copy only this section to an empty file; save/copy it as /etc/X11/xorg.conf
- restart X: $ sudo /etc/init.d/gdm start

My thunderbird is quick again!

What can we do to have this be fixed for everyone?

*) More information on xorg.conf: go to www.ubuntuforums.org and look
for "xorg.conf" and "karmic", you'll find plenty of threads
