All: I have a Ubuntu 18.04.3 LTS system that I bought with an integrated Intel display. I'm up to date with all updates. I bought an RTX 2060 GPU which I now am getting ready to install. I have never installed something on Linux which requires a new driver. I've read through all the instructions and I'm ready to start the install.
My question is: Is there a recommended way to "snapshot" the OS so that - if the install goes bad - I can boot and easily roll back to pre-install state? Windows has the notion of a "savepoint". Is there an analogous concept in Ubuntu? (Note - I've already backed up everything.)
Thanks
