I tried installing Nvidia drivers with terminal but it keeps on telling me that the nouveau driver is already installed and that I should uninstall but I can't uninstall it.
I think it's a driver issue but I'm not sure.
I installed Ubuntu desktop 18.04.1 LTS.
If you need any more info tell me.


You are on the right track, trying to use different drivers often fixes such issues, especially with more obscure GPUs. I recommend you first try installing the drivers from the Ubuntu repository, which should do everything for you, allowing you to bypass your current issue with installing. You can find instructions here: https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-18-04-bionic-beaver-linux

Basically run sudo ubuntu-drivers autoinstall and you are good.
