After upgrading from 16.04 to 18.04 I can't find a way to use the nvidia-settings either via command line or GUI.
When I run
sudo nvidia-settings I got the following message :
No protocol specified Unable to init server: Impossible de se connecter : Connexion refusée ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.
ubuntu-drivers devices produces :
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00001C8Dsv000017AAsd000039D1bc03sc02i00 vendor : NVIDIA Corporation model : GP107M [GeForce GTX 1050 Mobile] driver : nvidia-driver-396 - third-party free recommended driver : nvidia-driver-390 - third-party free driver : xserver-xorg-video-nouveau - distro free builtin
prime-select query outputs :
First I tried to install the drivers with :
sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt install nvidia-driver-396
Then I tried
sudo apt purge nvidia* sudo apt update sudo apt upgrade sudo ubuntu-drivers autoinstall
but no changes
I remember that in 16.04 I used a proprietary driver. But now there is no proprietary driver that I can select : software and updates
Let me know if any additional infos or command output could help to solve the issue.
I also have ukuu (ubuntu kernel update utility) and have the kernel up to date with the last version.
