After upgrading all packages my laptop gave a black screen on boot. After more digging, I figured out it was because of the nvidia drivers. As of now, I'm using the X.Org Nouveau open-source driver. I removed all Nvidia drivers using (from recovery mode) and this seemed to work.
```ssh sudo apt purge ^nvidia- ``` However, I'd like to use the Nvidia driver again ASAP. <hr> On trying to run (the recommended driver): ```ssh sudo apt get nvidia-340 ``` I got this: ```ssh dpkg: error: version '-' has bad syntax: revision number is empty dpkg: error: version '-' has bad syntax: revision number is empty update-initramfs: deferring update (trigger activated) INFO:Enable nvidia-340 DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/put_your_quirks_here DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/dell_latitude DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/lenovo_thinkpad Adding system user `nvidia-persistenced' (UID 126) ...
