I have a laptop with a Nvidia GeForce MX130 and an Intel i5-8250U. I'm using the Nvidia driver 440. When the laptop uses the battery, it works fine, but just when I plug the charger everything slows down. Even some "normal tasks" (like some Gnome animations, etc) get a little laggy. On games (which is the main use I give the Nvidia GPU) there's a considerable drop in FPS.

So, the question is, how can I fix this? Is there a way to trick Nvidia Driver so it is always working in battery mode? Maybe any other idea?

I appreciate your help in advance.

I'm running Ubuntu 18.04.3 with pantheon desktop, I installed the Nvidia drivers with the following command:

$ sudo apt install nvidia-driver-440

After the process was completed I restarted my pc. Now the NVIDIA X Servers Settings are installed and the app center shows the driver was successfully installed, but when I try to change the main GPU with prime settings, it doesn't work. Prime settings Additional drivers settings

I ran the following command to figure out what GPU is really working. This is what I get:

$ glxinfo|egrep "OpenGL vendor|OpenGL renderer"
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2)

I don't know if I have followed any wrong procedure. Thanks for your help!

Edit: This is what I get from running the following command.
