This bug is awaiting verification that the linux- nvidia-6.5/6.5.0-1014.14 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-nvidia-6.5' to 'verification-done-jammy-linux-nvidia-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-nvidia-6.5' to 'verification-failed-jammy-linux-nvidia-6.5'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
