This bug is awaiting verification that the linux-
nvidia-6.11/6.11.0-1003.3 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-noble-linux-nvidia-6.11' to
'verification-done-noble-linux-nvidia-6.11'. If the problem still
exists, change the tag 'verification-needed-noble-linux-nvidia-6.11' to
'verification-failed-noble-linux-nvidia-6.11'.


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. Thank you!
