I think I've the same problem. Updated yesterday, started my computer this morning and after the boot screen I'm only seeing a blinking cursor on a black screen. Tought it had something todo with lightdm, but nothing I tried fixed it.
After that I've removed all nvidia packages: sudo apt-get purge nvidia-* Rebooted, and choose the nvidia-331-updates driver I was using before (via Additional Drivers). This gave the blinking cursor again. So I've tried the other drivers (nvidia-331, nvidia-304, nvidia-304-updates), but none of these installed correctly. After every reboot I got the failsafe mode from Xorg. I've also tried to downgrade nvidia-common to 1:0.2.91.4, but this again caused to fallback in the failsafe mode. Ps. I'm also missing the nvidia-xconfig command, used it a few days ago. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371828 Title: After updating nvidia-common to 1:0.2.91.7, nvidia drivers are no longer in use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/1371828/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
