This sound like a GPU hang, and that would not always leave anything in Xorg.0.log. (I have seen that it has happened with very recent versions, though). There is more information about this kind of bug at https://wiki.ubuntu.com/X/Troubleshooting/Freeze , including information about how to get a batchbuffer dump, which we need for this kind of bug.
The Arrandale chipset is a very new one and this is the first freeze bug report I have seen for this chipset, so it would be nice if we could troubleshoot this and send it upstream to the intel developers. If you find the package upgrade that makes this happen, that would be useful information. Likely suspects are the linux kernel, mesa-packages and xserver-xorg-video-intel. Since there is a lot of development happening for this chipset, it would also be nice if you could test the newest mainline kernel from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=M;O=D (see https://wiki.ubuntu.com/KernelTeam/MainlineBuilds for more information). The newest there is currently 2.6.33-rc6, but -rc7 should also be available soon. If it isn't solved by a recent kernel, it would also be nice if you could test with the xorg-edgers PPA (https://launchpad.net /~xorg-edgers/+archive/ppa) before we send it upstream, so that we know the bug is still present in the latest code. -- [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
