Dual Monitor stopped working because of an issue with Optimus Manager

Hi. A few months ago, after installing Optimus Manager for the first time I have experienced some issues with my GPU drivers, since I could not use my nvidia RTX 2060 to play any games after installing Optimus and I also could not reinstall my drivers. This problem was solved after finishing a few tweaks in Optimus Manager, however yesterday after I came home from work my second monitor wasn’t working, which was weird because it was working perfectly fine before I went to work. Intrigued, I booted to Windows 10 and the monitor was working fine there, so I decided to reinstall my drivers again, but it just would give me an error message. Because I recognized this error, I tried changing GPU’s in Optimus but it just gave me this message

I have input the commands it showed me into the terminal but it keep giving me the same message, even after a reboot.
After that, I disabled Optimus, uninstalled it, deleted the nvidia.conf file, did sudo optimus-manager --cleanup , installed it again, but it still did not work and keep gaving me this same message (the monitor works fine without Optimus installed btw). Any thoughts on what might be the issue?
Here is my system configuration:

The latest Optimus Manager update is buggy and systems goes black. I’m currently ignoring the latest update after I had to timeshift back before the update. I had no issues with OM before and had to install it to get the nVidia card working properly. If you can timeshift back before the update and update anything but the OM version 1.4-3. Works for me.

I did not have a system snapshot from before the update, however, I used downgrade to well, downgrade optimus and everything is working smoothly again, thanks for the tip!

You are welcome! I use it before every major upgrade. It’s only a couple of clicks.

Yeah I know and I normally would do system snapshots but I only have one 500GB SSD and a Windows 10 dual boot, so I’m gonna get an external hard drive today to store my snapshots and other stuff :slight_smile:
