Comment 4 for bug 2057789

If it's not possible to backport the fix, that's fine - it would be good to just do it going forward?

Currently the ppa driver doesn't work fully (on GPUs with nvswitch) without the corresponding fabricmanager package, which does not exist in the ppa repo. That is the crux of the bug report.

If you try to install a specific ppa driver version, you need to hope the corresponding fabricmanager package still exists in the main repo (or find the historic version that matches, if that exists).
