I have a similar issue with nvidia drivers where X does not start at all and Ubuntu goes into login screen. Downgrading to 295.20 does nothing.
Is something wrong with the latest kernel, because the only way to boot is by using the older kernel (3.0.0+ in my case), not with the latest. Hope it helps. (12.04 LTS, 3.2.0-x kernel, lightdm, gnome3/unity, nvidia v295.20, 295.40) ** Tags added: nvidia -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/973096 Title: Nvidia driver causes xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/973096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
