a fresh installation of Ubuntu get's stuck on a purple screen when I try to load it. Restoring broken packages from recovery mode helps for a single session. I tried installing Nvidia graphics driver since my laptop has an external Nvidia card and an integrated intel one. But the Geforce is physically not working and can't be fixed so I get a black screen with Nvidia drivers, had to delete them from root. Is there any way of fixing this?

Install the NVIDIA drivers this way ... I assume you have NVIDIA GEFORCE 400 graphics or newer :
Remove the NVIDIA software you have tried to install.
Highlight the Ubuntu menu entry and press the E key.
Add nouveau.modeset=0
to the end of the linux line.
Press the F10 key to boot into the Ubuntu system.
When the login screen appears press Ctrl+Alt+F1.
Enter your user name and password and then execute :
sudo apt-get purge nvidia*
sudo reboot
Install the NVIDIA drivers from the Ubuntu repositories.
Highlight the Ubuntu menu entry and press the E key.
Add nouveau.modeset=0
to the end of the linux line.
Press the F10 key to boot into the Ubuntu system.
When the login screen appears press Ctrl+Alt+F1.
Enter your user name and password and then execute :
sudo apt-get update
sudo apt-get install nvidia-352 nvidia-prime
sudo reboot
Now adding a boot parameter is not necessary anymore.
Switch between graphics from NVIDIA X Server settings.
