I’m running nvidia 455.45.01 on my Arch Linux computer, and when upgrading to linux 5.10, I noticed PRIME Synchronization wasn’t working anymore (I’m experiencing screen tearing). Upon downgrading to linux 5.9.14, it works again.
It reminds me of this issue. Could it perhaps be related?
also with 5.10 and optimus laptop, nvidia card is always active, on 5.9.16 all is working correct
With the 460.27.04 driver PRIME synchronization seems to be working again (Linux 5.10.4).
Can confirm! Thanks :)
