I had a similar issue, but now have 9.10 running smoothly. It seems that the upgrade process disables all proprietary drivers, but does so without updating xorg.conf to use the default non-proprietary drivers.
All I did to fix this was login via a rescue shell, edit xorg.conf so that nothing was listed in the "Device" section. hal recgnised my hardware and I could boot normally (of course my twinview was now broken). I installed the proprietary driver and reverted to my old xorg.conf - no issues. The fix - just search xorg.conf for proprietary drivers and edit accordingly - can probably be included in the uprage sequesnce quite easily. -- upgrade breaks graphic drivers and x, preventing login or startx https://bugs.launchpad.net/bugs/464591 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg 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
