CLosing this bug because I posted in the wrong package (lightdm, even though it has nothing to do with lightdm).

Instead of the screen showing the first installation options, I get a screen like the one shown in the attachment (a photo of what can be seen). If i look at the logs (switching to another terminal), the only thing that might indicate a problem is this entry (there are thousands of instances of it) in /var/log/kern.log: "[drm] nouveau 0000:01:00.0: PFIFO_CACHE_ERROR - Ch 2/2 Mthd 0xNNNN Data 0xNNNNNNNN" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1058497/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
