Failed to start Light Display Manager, seemingly because of NVIDIA driver?

Today my installation failed to boot Light Display Manager. After booting from a live USB and doing some reading through `/var/log/Xorg.0.log’, it seems to have been due to the proprietary NVIDIA driver I installed a while back failing to boot. Here’s the output of Xorg.0.log

And here’s the output to inxi --admin --verbosity=7 --filter --no-host --width

I’m not too sure what I do from here, please advise.

  1. How did you install the nVidia driver exactly? Because I’m on:

    [ 3.996] (II) NVIDIA dlloader X Driver 465.31 Thu May 13 22:19:15 UTC 2021
    [ 3.996] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs

    since the last update and you’re on:

    [ 60.158] (II) NVIDIA dlloader X Driver 460.84 Wed May 26 20:07:09 UTC 2021
    [ 60.158] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs

    and your GeForce GT 730 is still supported by the 465.31 series.

  2. Have you tried booting into your fall-back kernel? (Ideally 5.4 LTS as you seem to be on 5.10 LTS)

:thinking:
