<pre>Hello,
<span class="quote">> AC: core 0 MHz memory 0 MHz</span >
means your GPU is actually suspended: since you have an Optimus configuration,
the NVIDIA GPU will suspend automatically if it hasn’t received any work to do
in a short while. Try for example to run `DRI_PRIME=1 glxgears`, keep it
running and reissue the cat command: you should not see actual clocks for on
the AC line.
Have a look at <a href="https://nouveau.freedesktop.org/wiki/Optimus/">https://nouveau.freedesktop.org/wiki/Optimus/</a> to learn how to
configure Prime.
As for the system hang when trying to reclock a suspended GPU, patches have
been sent to the Nouveau mailing list, but haven’t been merged yet. You can
find them here:

<span class="quote">> And when i launch a game (Tyranny), it does not work.</span >
What is not working? If you didn’t specify anything, the game should run on the
“primary” GPU by default, which quite often tends to be the Intel GPU.</pre>
