Hello fellow users of Ubuntu some days ago I tried to configure an Nvidia Prime profile since my PC was only using Intel and wasn't powerful enough.
I only typed one command wich I can barely remember and then had to shutdown my PC since I had other things to do. Command, which is the following:
sudo apt-get install nvidia-361
[EDIT] : I might have followed this guide : 'PRIME Profiles' tab missing in NVIDIA X Server Settings (Ubuntu 16.04)
Today I booted up my PC and everything started good, but after the purple Ubuntu screen with the dots it doesn't show anything!
That's is my problem thanks for helping me! ^^
P.S.: My graphic card is an Nvidia GeForce 940MX with 2GB dedicated ram.
