Q: Pop OS: install multiple nvidia drivers

I'd like to configure a Windows VM in PopOS. I have 2 GPUs in my system, a GTX 1660 Super and a GTX 550 Ti. The PopOS installation came with the nvidia 440 driver pre-installed, which made use of my 1660 Super with ease. However, I see that this driver doesn't support my 550 Ti. Based on my resea...

Hey @user3140225!

I installed Anaconda couple of hours ago.

I felt that my PC was a bit slow after installation.

So I decided to uninstall Anaconda

I tried the instructions given in this website: docs.anaconda.com/anaconda/install/uninstall

I used anaconda-clean and did simple remove using rm -rf ~/anaconda3

I didn't understand the "Removing Anaconda path from .bash_profile" part mentioned in the website.

Can you help me please?

@technastic_tc It's strange that you felt a difference on your PC. The only thing that should be different in terms of speed is (I think) opening a Terminal for the first time.

To remove the path open a terminal and run: nano .bash_profile

Find the line export PATH="/Users/jsmith/anaconda3/bin:$PATH" (it should contain your username instead of jsmith) and delete it

Save the file with Ctrl+o, close nano with Ctrl+x and restart your terminal

Also see here for info about the PATH variable.

@technastic_tc OK, that's fine. Mine is also empty. Also check your .bashrc for code that initializes conda, similar to the following screenshot. If it exists, just delete that part of code.
