when NVIDIA released version 415 of their drivers it replaced version 410 in the Manjaro repos. Unfortunately I believe there is an issue with version 415 (https://forum.manjaro.org/t/nvidia-lock-up-on-restart-nvrm-xid-56/69273).
Due to this issue I am now going back to version 390 on my PC. But when I check the NVIDIA versioning information I see that version 410 is a long term support version, currently at 410.78: https://devtalk.nvidia.com/default/topic/533434/linux/current-graphics-driver-releases/
Now I am wondering if it would be possible to get the 410xx driver series back in Manjaro.
