After getting Ubuntu login loop on Ubuntu 16.04 and following the online tutorial from here, I reinstalled lightdm successfully and after reboot, I got this error. It repeats over and over again. The login page does not even load. I am wondering if anybody has seen this before:

  • So did you reinstall lightdm or gdm? From what I understand, they're incompatible. – wjandrea Jan 12 '18 at 0:09
  • I reinstall lightdm with sudo apt-get purge lightdm && sudo apt-get install lightdm and i got this error – sam_com Jan 12 '18 at 0:13

the problem was with the invidia driver, the solution was to reinstall the nvidia driver.

Sudo apt-get purge nvidia-*
Sudo apt-get install nvidia-*** (***= is the version of the nvidia)
