Nvidia drivers don't let me log in

I have been playing some games on my Ubuntu 18.04 Thinkpad, and decided to switch to the nvidia drivers. I selected their drivers from software and updates, clicked apply, and rebooted. When I entered my password, it stayed on a black screen, and I couldn't move my mouse.

SOLUTIONS I TRIED:

  • Changing the owner of ICEauthority (there is no Xauthority file in my home directory) to myself
  • Installing DKMS

I would like to know the problem, as well as the solution, if there is any.

Thank you in advance.

EXTRA INFORMATION:

Did you remove "nomodeset" from your kernel boot line? Please add the output of cat /proc/cmdline and lshw -C video to your original post.

You're still using the nouveau driver, Did your turn off secure boot? That's incompatible with the Nvidia driver. Check the files in /etc/modprobe.d for anything blacklisting the nvidia driver. Only nvidiafb is OK to blacklist.

Only nvidiafb is blacklisted, and how do I know if secure boot is on? @ubfan1

Check your machine's UEFI Settings/BIOS for turning off secure boot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
