Eight days ago, I applied "Workaround C" (upgading to the 2.11.0 xserver-xorg-video-intel driver, from https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes).
Note that upon reboot I could not get the normal Gnome logon screen but instead had the following errors:
"
! Ubuntu fonctionne en mode graphique dégradé.
L'erreur suivante est survenue. Vous aurez peut-être besoin de mettre à jour votre configuration pour résoudre cela.
(EE) Intel (0): No kernel modesetting driver selected.
(EE) Screen(s) found, but none have a usable configuration.
"
the "No kernel modesetting driver selected" message made me think to the "Workaround A", which I applied immediately. Then after rebooting the logon screen returned to normal state.
Since then I had about 4 hangs, and I am using my computer only about 1h30 a day... The 3 or 4 last hangs were different: the GUI was completely frozen: it did not answer the mouse or keyboard clicks (the mouse pointer was movable though). However I could CTRL-ALT-F1 and get a text logon and then could issue a "sudo reboot": may be there is a smarter thing to do than reboot ?
before rebooting I did a "dmesg": the relevant errors are the same than in my previous post (#194):
"

My kernel is up to date (ubuntu update line - 2.6.32-24.41).
