This bug and can be removed. Perhaps this laptop's Nvidia graphics card can't handle Unity 3D. I still need to find a definitive answer. I don't recall the 11.04 installer telling me, "Your graphics card won't support Unity 3D," or a similar message.
Waited a couple of weeks and booted this laptop. Found that I could get to a garbled white/black console where I blindly logged in and performed: sudo apt-get update sudo apt-get upgrade Many packages were upgraded. Rebooted the system and logged in but Unity 3D didn't appear correctly. Moreover, saw blinking red, green, white, black, blue screens when I attempted to revive the system from suspension. This has been indicative of an improper setting of the Nvidia graphics card in the past. I removed the restricted Nvidia driver 173 to test Ubuntu's Nvidia driver. Installed the Unity 2D driver and so far that is working for me. ** Package changed: linux (Ubuntu) => nvidia-graphics-drivers-173 (Ubuntu) ** Changed in: nvidia-graphics-drivers-173 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-173 in Ubuntu. https://bugs.launchpad.net/bugs/774554 Title: upgrade from 10.10 to 11.04 failed _______________________________________________ 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
