Reference: #104 (comment) While I don't use KDE I have similar issues with sway although the only application I encountered such crashes where firefox and thunderbird. The issue here is a race ...
nvidia test VM (with gpu passthrough), main machine, HTPC (stuck on F39 due to polaris atm but moving to F40 soon once some patches land) on the go hobby work laptop, legion go, deck (running steamos)
2 penguin plushies my friends sent me as secret santa gifts as jokes (the sunglasses on the small one was a dlc that got sent to me last year, didnt know my secret santa gift came with a season pass)
bunch of controllers i use for testing (plus another 40 in a drawer behind the desk)
they need to be detected as different GPUs, if you have lets say 2x 3090s you need to add custom scripts tailored for your card into initramfs, this is not something we do
yeah since you need to make a custom script to manually bind the correct card by pci address to vfio-pci at boot before nvidia driver grabs the card as vfio-pci only understands vendorid:deviceid which would be identical for the 2 cards
not something we support sadly, if you know how to set it up feel free to PR but i have no way to test it since i just do different cards as it is 1000x easier
like, i just dont have any real usecase where i would have a good use for the second 4090 (my boss sends me the PC as a gift), so i figure something out where i can put it to good use
