gpu problems when booting parrot os

I try to install Parrot OS on an old windows PC that has GPU of Nvidia GeForce 710. When I boot it in the default mode, It seems like it renders but then I get an error saying: nouveau 0000:01:00.0: DRM [DRM/000000001: kmsOutp] [HDMI head:0 enable: 1 max_ac_packet:15 ... Then, I tried to boot while selecting disable nouveau and nvidia GPU and it boots ok. Later, I tried to do: sudo apt install nvidia-driver But I got an error saying: "The system has a graphic card which is no longer handled by NVIDIA driver..." I tried to download manually the driver and install it (had to stop and start lightdm for it) but I got errors. Currently, I'm stuck with no nvidia and nouveau which makes the resolution huge. When I try to use xrandr, it keeps failing. I tried to use cvt to add a new resolution but it won't add. How can I continue here? I feel like I'm completely stuck. Thank you! **SOLUTION:** So after a while the following solution did the thing: 1. Make sure to add nouveau to blacklist-nouveau.conf. blacklist nouveau options nouveau modeset=0 alias nouveau off 2. sudo apt install nvidia-tesla-470-driver.
