== Supported devices ==
* This guide is valid for Airtop, Airtop2, Airtop3
== Prepare installation media ==
* A USB DVD-ROM drive or a USB Flash drive of at least 2GB should be used as installation media
* Download [https://www.linuxmint.com/edition.php?id=254 267 Linux Mint 19 .2 "TaraTina" - Cinnamon (64-bit)"]
* For installation with a USB DVD-ROM - flash the downloaded image directly onto a DVD
* For installation with a USB Flash drive, please follow [http://community.linuxmint.com/tutorial/view/744 How to install Linux Mint via USB] tutorial
== I3M Panel ==
* 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>
</pre>
* Note, the package adds "acpi_enforce_resources=lax" string to the kernel boot line
$ sudo apt install mint-meta-codecs i965-va-driver gstreamer1.0-vaapi vainfo
</pre>
Then run vainfo command, you should see list of supported profiles, for example on Airtop2Airtop3:
<pre>
$ vainfo
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.1 (libva 2.1.0)
vainfo: Driver version: Intel i965 driver for Intel(R) Kaby Coffee Lake - 2.1.0
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
== Nvidia graphics card drivers ==
<pre>
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt update
$ nvidia_driver=$(apt-cache search "nvidia-driver-[0-9][0-9][0-9]" | grep -o "nvidia-driver-[0-9][0-9][0-9]" | sort | tail -1)
$ sudo apt install $nvidia_driver vdpauinfo mesa-vdpau-drivers vdpau-va-driver --install-recommends
$ sudo reboot
</pre>
* 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 Airtop3 with Quadro RTX 4000 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
