The latest Xorg 1.19 has been released and it is said to solve the tearing issues with Nvidia + Intel Optimus setups. I have been struggling with that a lot and can't wait to try it.
I wonder: Are there any update guides on how to update xserver + kernel for the new Xorg release? I failed to find any documentation on that. I realize I can download the Xorg 1.19 and execute the install, however not knowing the documentation, I am not sure how to roll back in case of catastrophic failure.
Additionally, I am on kernel 4.4 - I realize that the new Optimus support needs (I believe) kernel 4.5 or higher. If wanting to install it on my local machine, I believe that the download compiles it on that machine before installing it. Does that mean that I should install the kernel before installing Xorg so that the compilation would be against the kernel that I am running?
