I did a clean installation of Ubuntu 16.04 and fully updated the system via terminal. After that, I installed nVidia driver downloaded from its official page. Now I'm stuck in infamous login-loop and I can work only with tty. I think solution from this question would work for me, but there's the problem - the internet doesn't work, so I can't finish sudo ubuntu-drivers autoinstall. Neither Wi-Fi nor USB tethering from phone works.

Here are outputs for commands I tried:

ifconfig wlan0
wlan0: error fetching interface information: Device not found

lspci -nn | grep 0280
03:00.0 Network controller [0280]: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)

rfkill list all

  • Better to just remove whatever Nvidia drivers you installed: sudo apt purge nvidia* and start over. If you're unsure about how to correctly install Nvidia drivers and especially what version to choose from, please post anew question. –  Feb 14 '17 at 11:25
  • Not what I wanted, but still better than login loop, so thanks. Do you think I should also delete modprob file that nVidia installer created and reinstall Nouveau driver? – PKM Feb 14 '17 at 11:43
  • ??? How exactly have you installed those drivers? –  Feb 14 '17 at 11:45
  • I downloaded .run file from nVidia official page, went to tty, used sudo service lightdm stop to stop X server, and run the installer. And then I did what installer wanted me to do (remove Nouveau, and let it add modprob file to automatically disable it in case if it was installed again). I knew nVidia drivers usually bring problems, that's why I did it on clean installation, but I hoped I will be able to somehow make it work. – PKM Feb 14 '17 at 12:04

    Not surprisingly (expected actually), you used the not recommended method. Nvidia drivers are available directly in the Ubuntu repositories (or PPAs if a newer version is needed). Now, you may need to run the Nvidia installer again as I believe it'll give the option to uninstall. No, Nvidia drivers usually don't bring problems unless you install a wrong version. –  Feb 14 '17 at 12:19

    The command should be sudo ~/installation_file.run --uninstall where installation_file must match the name in the file you downloaded from Nvidia. –  Feb 14 '17 at 12:23
