Comment 44 for bug 477256

The laptop acquired an extra 512MB of RAM yesterday, and I thought it might be useful to reinstall Xubuntu with all updates and see what happens. Installation method was to install a command-line system first, then install Xubuntu-desktop plus do other updates before rebooting and logging into the Xubuntu desktop.

Unfortunately, the system froze twice. The first time after 1-3/4 hours and the second a lot sooner - probably around 30 minutes, maybe less.

I've run the laptop for many hours at a time while using lxde/openbox or openbox on its own. I've tried using just the xfce4 package as well and it seems to be fine, though this might need a bit more testing.

Therefore, I'm inclined to conclude that one or more of the Xubuntu-desktop components is/are interacting with xserver-xorg-video-intel to cause the freezes.
