Indeed, there is a 'intel_drv.so' in the /var/log/Xorg.0.log. In the package
manager, I can see only 'xserver-xorg-intel' (latest version - 2:2.9.1-3ubuntu5
but no 'xserver-xorg-drv-intel'. I don't know from which package this
'intel_drv.so' is coming from.

Regarding the type of crash, it is a hard crash as if you take the plug of
the socket or you pressed the off button. Could it be related to the CPU
which is over heating? As well, the crash doesn't happen all the time is
cannot be reproduced all the time with the same flash video. At the moment,
it happens only when viewing a flash video on full screen mode.

Could not identify the issue with the links Alex mentioned, but this is
probably because I know exactly what I'm looking for.

Output of "grep Loading /var/log/Xorg.0.log":

(II) Loading /usr/lib/xorg/modules/extensions/libextmod.so
(II) Loading extension MIT-SCREEN-SAVER
(II) Loading extension XFree86-VidModeExtension

Thank you again for all.
