* Integrated interactive information monitor [[Airtop:I3M | I<sup>3</sup>M]] is a GUI system integrated in the front panel of Airtop
* Download and install the following package for Airtop or Airtop2:
<pre>
$ sudo dpkg -i airtop-fpsvc_systemd.deb
...
Created symlink /etc/systemd/system/multi-user.target.wants/airtop-fpsvc.service → /lib/systemd/system/airtop-fpsvc.service.
Created symlink /etc/systemd/system/multi-user.target.wants/gpu-thermald.service → /lib/systemd/system/gpu-thermald.service.
Then run nvidia-smi command, you should see current NVIDIA card status:
<pre>
$ watch -n1 nvidia-smi

== MPV media player ==
* Well known free and open-source multimedia player
* Supports GPU accelerated video decoding including CUDA decoding on NVIDIA GPUs and gives excellent playback quality
* Compatible with the most popular video formats
$ sudo apt install mpv youtube-dl
For example, Airtop2 with GeForce GTX 1060 is capable to play 4K UHD using CUDA video from the local filedecoding without significant system load:
<pre>
$ mpv -fs --hwdec=cuda ~/Videos/jellyfish/jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv
Playing: ~/Videos/jellyfish/jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv

Or the same content directly from the youtube:
<pre>
$ mpv -fs --hwdec=cuda https://www.youtube.com/watch?v=j4oBg8capW8
