The above bug report was from a VM system without access to an Nvidia GPU. Here's information from a real PC with a real Nvidia card in it.

The only reason the system is functional is because nouveau probed first: # cat /proc/modules | grep -E '^nouveau|^nova_core' nova_core 176128 0 - Live 0xffffffffc0efb000 nouveau 3178496 15 - Live 0xffffffffc0a00000 If nova_core had probed first, it would have claimed the GPU instead. ** Summary changed: - Ubuntu 26.04 linux kernel has non-functional nova-core GPU driver enabled, breaking systems with Nvidia GPUs + Ubuntu 26.04 linux kernel has non-functional nova-core GPU driver enabled, conflicting with nouveau -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2150845 Title: Ubuntu 26.04 linux kernel has non-functional nova-core GPU driver enabled, conflicting with nouveau To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2150845/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
