Synaptic Package Manager is the easiest way to do that. Have you installed that APP from the Software Center?
Launch Synaptic, then in the search box type optimus. You will see a green box next to optimus indicating its installed. Right click on it, mark for removal, DON'T do complete removal or it will possibly remove dependencies.
Hi, im having a similar problem. I couldn't find a solution for amd/nvidia on the internet. You could try using Pop_os, it takes care of drivers and transitions itself. I really liked Zorin OS, but I can't use it efficiently.
I am running POP and I can do hybrid or dedicated. But I choose to keep it in dedicated Nvidia only, cause like, why wouldn't you? I want all the performance I can get, YES! HEHE
Oh… hmmm. I mean I want more battery life as I usually use my computer for stuff other than gaming but I’m debating pop now. But I really like Zorin. I dunno lol. Pop doesn't allow for secure boot though right?
Always, always have SECURE BOOT disabled when using any Linux distribution. And always have TPM turned off as well, that is also not needed in Linux. It is also recommended to turn of FAST BOOT as well, as that can sometimes cause problems.
SECURE BOOT & TPM are Windows only, we don't use them here.
Mostly.
Some apps will still struggle with it. And this is an Ubuntu thing, not a Zorin OS thing.
Microsoft signed most of the packages for Ubuntu, but not all.
