I'm looking for a similar quest, But instead for a Proprietary Video driver. I'm running 16.04LTS, and my machine has a NVIDEA GTX card. Occasionally, the internet service goes wonky at home, so I'll downgrade to the generic X.ORG Nouveau driver, shut-down, eject the main boot drive, and take it with me with a Laptop & an external dock, to a local coffee shop (Better than hauling the whole desktop server to there.) I'll boot the drive externally on the laptop, run the updates (apt-get update/upgrade ,) power-down, bring the drive back home, re-insert to the main machine, then reboot.. BUT.... I cannot return to the proprietary driver... resulting, slugging running video. Can the proprietary drivers be recovered, and reinstalled? Or, do I simply have to wait til the Internet is back up local to the server? Thanks, Stephen (gelfling6)

  • How did you install nVidia driver? If you install from nVidia you have to run commands to re-configure it for every new kernel. Best to always install from Ubuntu repository. But you may not get auto update if laptop not also nVidia. Not sure exact command. sudo service lightdm stop & sudo dpkg-reconfigure nvidia-current or your specific version of nvidia? – oldfred Oct 16 '17 at 22:57
  • The driver was originally installed via the System Settings -> Software & Updates -> Additional Drivers, the drivers are loaded via NVIDEA that method. I was able to restore it when the WiFi at home was active again (shared, and yes, Legally.), but, yet again, it's gone down.. (wonky router/Firewall used, and the router is not easily accessible.) – Stephen Griswold Nov 15 '17 at 23:28
  • Check if you downloaded newer kernel & then you do not have nVidia driver. dkms status It may be easier just to reinstall as it has to be reconfigured into kernel with dkms. See what versions are available: ubuntu-drivers devices and auto install recommended (same as System Setting screens you used). sudo ubuntu-drivers autoinstall – oldfred Nov 15 '17 at 23:42
  • Okay, I don't have the drive handy.. the 'flakey' WiFi is back up again (Hotspotsystems firewall.. SHEESH!) and I was able to get it back by re-installing the driver again.. But, just for gall, I'll pull the drive, and give this a shot tomorrow. Thanks! Stephen – Stephen Griswold Nov 17 '17 at 00:39
