On the Nvidia page its explained on how to install a driver using ‘transactional-update’ but this seems to be missing from Teal. Is there an alternative way on how to install the drivers? https://en.opensuse.org/SDB:NVIDIA_drivers

Hmm, yep Teal does not support transactional-update.. it "might" work to use zypper with the new repo, but I haven't tested it..
