Ubuntu 17.10 Drivers Not Found/Working Properly?

  • 772

I recently upgraded from Kubuntu 17.04 -> 17.10 using the upgrade tool. All of my programs/settings/personalization is ok, but many of the drivers are either missing or nonfunctional. This includes sound (Both Integrated Speakers, USB Speakers, and Bluetooth Speakers) Additionally my USB Bluetooth adapter may be malfunctioning due to the driver(No Sound Upon 17.10 Upgrade).

This also includes my USB Wi-Fi adapter as well. The internal Wi-Fi card may still be disabled because I had to to enable the external USB one (Which has a higher range than my internal antenna. Basically all the steps we did to enable the USB antenna (Wireless antenna does not appear despite its driver being installed)

I should note that graphics drivers appear to be fine (At least from the System Settings Dash anyway.... I'm using an Nvidia graphics driver and all appears to be well on that frontier)

I'm still new to the upgrade, if I find anything else that broke, I'll post it.

Edit 0: I should note that the Wired connection that I'm using is ok, and that I can connect to the network from there, and that's how I'm making posts. Seeing a similar question to the Wi-Fi issue I went to (No internet after upgrade to 17.10) and they linked me to (https://askubuntu.com/a/907249/645874) I attempted the fix and got a green status.Green Status The issue persists, although, granted I haven't had time to restart the system yet.

Edit 1: I executed most of the lines from your solution, but hit a snag on the dkms region.

sarah@ConvergentRefuge:~$ sudo dkms uninstall rtl8812au/5.2.9
Error! Could not locate dkms.conf file.
File:  does not exist.
sarah@ConvergentRefuge:~$ sudo rm /usr/src/rtl8812au-5.2.9
rm: cannot remove '/usr/src/rtl8812au-5.2.9': No such file or directory
sarah@ConvergentRefuge:~$ sudo rm -rf /usr/src/rtl8812au-5.2.9
sarah@ConvergentRefuge:~$ sudo rm -rf ~/rtl8812au-driver-5.2.9
sarah@ConvergentRefuge:~$ rm -rf rtl8812au

sarah@ConvergentRefuge:~$ sudo dkms add -m 8812au -v 4.2.2
Error! Could not find module source directory.

I also tried a variation of it:

sarah@ConvergentRefuge:~$ sudo dkms add -m rtl8812au -v 4.2.2
Error! Could not find module source directory.
Directory: /usr/src/rtl8812au-4.2.2 does not exist.

    With a working internet connection, open a terminal and enter these commands one at a time:

    sudo apt update && sudo apt install git

    If it is already installed, please just continue.

    First, let's clean away the steps that we've shown are not working:

    sudo dkms uninstall rtl8812au/5.2.9
sudo rm /usr/src/rtl8812au-5.2.9
sudo rm ~/rtl8812au-driver-5.2.9
rm -rf rtl8812au

    Next, please do:

    git clone https://github.com/gnab/rtl8812au.git
sudo cp -r rtl8812au  /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

    Reboot and tell us if the wireless is working.
