Maybe I got it! I had to reinstall (yet again!) the ubuntu-desktop package:
Note that I had to **install** it and it wasn't saying "already install, he just installed it has if it did not have it (and I believe it wasn't having it)... see attachment to look at what had been installed ii ubuntu-desktop 1.193 After rebot, no complaint about graphics card, GNOME session available. So I believe there is something in kernel updates messing with ubuntu-desktop package in a strange but reproducible way, should I change the title to this bug? ** Attachment added: "ubuntu-desktop_install" http://launchpadlibrarian.net/42665481/ubuntu-desktop_install -- lucid lynx - login screen stuck in a loop - SYSTEM BROKEN https://bugs.launchpad.net/bugs/516520 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
