Comment 124 for bug 439138

I did an aptitude safe-upgrade today.
Since then I have the problem, that xorg eats 100% cpu (1 core) and the system is very unresponsive.

I use en encrypted root partition and my gpu is "00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)".

This bug was NOT FIXED in cryptsetup - 2:1.0.6+20090405.svn49-1ubuntu6 because i have
2:1.0.6+20090405.svn49-1ubuntu7 installed and the problem still existes!

I attached my aptitude log, please read it, as the bug was introduced in on of the upgraded packages. Before the upgrade today everything was fine.

PS: we need some functionality to undo an upgrade!
I first thought that it was an xorg failure so i tied to downgrade but apt cannot find the version before the upgrade anymore

~/ apt-show-versions xserver-xorg -a
xserver-xorg 1:7.4+3ubuntu7 install ok installed
xserver-xorg 1:7.4+3ubuntu7 karmic archive.ubuntu.com
xserver-xorg/karmic uptodate 1:7.4+3ubuntu7

~/ sudo apt-get install xserver-xorg=1:7.4+3ubuntu5

E: Version »1:7.4+3ubuntu5« für »xserver-xorg« konnte nicht gefunden werden
translation: Version »1:7.4+3ubuntu5« for »xserver-xorg« could not be found

Please fix this soon! I cannot use my computer like that and like i said i also cannot undo the upgrade.
