So currently I was able to boot up the openSuSE Tumbleweed installer by adding nouveau.modeset=0 option to the kernel line and install a full working GUI system. yay! for first rolling release distro that I tried.
I did try getting the NVidia driver installed following the https://en.opensuse.org/SDB:NVIDIA_the_hard_way
guide. I guess everything went fine until I rebooted post installation. The login screen would never come up at all. X (I assume or gdm) would always crash with a Chrome like crash/sad face emoticon giving only a button to log out. I could still get a command line under ctrl-alt-f(1-6).
It will make sense to open a new thread to get help with that. but for now the Intel integrated graphics card is being adequate.
Oh btw, even setting nvidia.modeset=0 did not work when it crashed the GUI session and I wanted it to fall back to the intel card. Since I can get in the terminal, is there a way to blacklist nvidia specifically?
p.s. Ending a solved thread with a question is not against the laws of the nature, is it?
