Andrew, you shouldn't need to reinstall Xubuntu many times to find the package upgrade that causes this. If you do a `sudo apt-get dist- upgrade` you can save the list of packages that is getting upgraded and choose "no" in order to not upgrade right away. You can then run `apt- get install packagename` in order to upgrade only a specific package and its dependencies. If you install too many packages, you can also downgrade. If there has been a previous upgrade (unlikely in your case) you can find the old packages in /var/cache/apt/archive and install them with `dpkg -i deb-file-name`. Otherwise you can find the deb-files on the installation medium. If you uncomment it in /etc/apt/sources.list, you should also be able to downgrade with `apt-get install packagename=version`.
I think this is muck more likely to be caused by not-quite-mature drivers than your power problems. I will set the status of this bug report to Incomplete for the time being to keep it off our radar until you get your system working again. Once a another comment is added it pops back again, since we typically only filter away Incomplete bugs without responses. ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided => High ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- [Arrandale] Freeze on login after update https://bugs.launchpad.net/bugs/518201 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
