I am setting up a new Kubuntu install for the first time. My laptop (Dell Alienware M17 R2) contains an nVidia GTX970m adapter in addition to the integrated Intel HD 530 adapter. Only the Intel Adapter shows up initially so I installed drivers for the nVidia adapter using "sudo ubuntu-drivers install" and rebooted. This caused the audio, Bluetooth and wireless to become disabled. They show up as present in lspci but I see no way to activate them after installing the graphics drivers. And they show device not present when I select audio or bluetooth from Settings. The wireless connection is listed in settings but is inactive with no way to activate it that I see. Any ideas what to do?

I tried removing the drivers using:
sudo dpkg -P $(dpkg -l | grep nvidia-driver | awk '{print $2}')
sudo apt autoremove
That successfully removed the drivers. Rebooted and still had no audio, Bluetooth or wireless.
Did a clean install and once again had audio, Bluetooth and wireless.
While researching how to uninstall the drivers it indicated there were alternative drivers already in the current LTS build so maybe I am already using the GTX adapter rather than the integrated Intel one.
But I still don't understand why using the actual driver from nVidia killed audio, Bluetooth and wireless. -
the best way to change to the propriatary drivers after install using the kernel divers is to run
sudo software-properties-qt
in a terminal window.
under the additional drivers tab you should find the drivers for your nvidia card... choose the recommended one.
it should not affect your other drivers tho for sound if you were relying on your gpu for sound output then it might

Thank you.Using that tool I selected the first option which was the only one tested. Rebooted and audio, Bluetooth and wireless all are working. It seems the original way I had used installed too much else and not just the graphics drivers
