Quick update on this: NVidia's contempt for Linux users continues unabated.
The latest Linux drivers still require a license key to function with
consumer cards, not only that but they have also changed those keys
during the stable updates to their drivers: the latest 331 and 334
drivers now require different keys than they did before.
With the 337 branch it is even worse: the newer keys are accepted, but
the API has changed and so the codec needs to be rebuilt against the
newer API headers, which have not been released yet.. So this one is a
complete no go at present.
It also means that the nvenc codec in xpra is actually tied to specific
versions of the drivers, which is another system maintenance headache.
Start of rant:
" A/tyrant/device is one that refuses to allow users to install a
different operating system or a modified operating system. These devices
have measures to block execution of anything other than the “approved”
system versions. We also refer to this practice as/tivoization/."
"Every nonfree program has a lord, a master--and if you use the program,
he is your master." - RMS
