    Is it possible to disable hardware video decode acceleration client side?¬† I’m running into some behaviors that I think are possibly contention related when I’m using the NoMachine client while another app is making extensive use of the integrated GPU. I haven’t had any luck forcing it to use the other GPU, so I’d like to try just doing software decode, but I haven’t found a way to do so.

    The specific symptom is my CPU utilization hits 100% after a few minutes once I connect to a remote. The usage appears to be a really large amounts of interrupts being generated, and it also causes my GPU use to spike from 30-40% from the other app to near 100% as well, and the system bogs badly (presumably the interrupts).

    This would be on a Windows 10 machine for the client, Ubuntu VM on the server side.

    Thank you!



    You can disable Client hw acceleration per session, by changing the Display settings in the NoMachine Menu Panel. See the following image.

    You can change default settings for the specific user by editing $HOME/.nx/config/player.cfg file and changing default value¬† <option key=”Enable hardware accelerated decoding” value=”false” />

    Please note that for editing the player.cfg file NoMachine player should be closed.



    Ah, thanks! I was looking for settings prior to establishing the connection.
