Supported devices

  • This guide is valid for Airtop, Airtop2, Airtop3

Prepare installation media

LiveUSB installer crash on Quadro RTX 4000

  • In case your machine is configured with Quadro RTX4000 and experience crashes/freezes while LiveUSB installer running, please expand and follow the below:
  • To perform boot into "Safe Graphics" mode, add "nomodeset" parameter to the kernel boot line:
    • Power-on the Airtop3 with LiveUSB installer
    • Boot menu will appear, default entry will be "Start Linux Mint 20 Cinnamon 64-bit"
    • Press [e] to enter edit mode
    • Add "nomodeset" after the "splash", the end of line will look like "quiet splash nomodeset --"
    • Press [F10] to continue the boot
  • You will need to add "nomodeset" option once again, after base installation of Linux Mint and reboot
  • The problem will disappear after installing Nvidia graphics card drivers


Base installation of Linux Mint

  • Follow the standard Linux Mint installation procedure - choose timezone, partitions, username, password etc.
  • Disconnect the installation media and reboot.
  • Login using previously selected username and password.

I3M

  • To install I3M Linux Daemon on Airtop, please expand and follow the below:
  • Download I3M monitoring tools:
$ sudo wget https://fit-iot.com/files/download/airtop/sw/I3M/Linux/airtop-fpsvc -O /usr/local/sbin/airtop-fpsvc
$ sudo wget https://fit-iot.com/files/download/airtop/sw/I3M/Linux/gpu-thermald -O /usr/local/sbin/gpu-thermald
$ sudo chmod +x /usr/local/sbin/*
  • Fix dependencies:
$ lib_path="/usr/lib/x86_64-linux-gnu"
$ [ -e $lib_path/libsensors.so.4 ] || sudo ln -s $lib_path/libsensors.so.*.0.0 $lib_path/libsensors.so.4
  • Create file /etc/rc.local with the following content:
#!/bin/bash
modprobe i2c-i801
sleep 1
/usr/local/sbin/airtop-fpsvc
[ "$(lspci -nn | grep VGA | grep NVIDIA)" ] && /usr/local/sbin/gpu-thermald
exit 0
  • Make it executable:
$ sudo chmod +x /etc/rc.local
  • Ensure I3M panel is working
$ sudo /etc/rc.local
  • Reboot, ensure I3M panel is still working
$ sudo reboot

Missing Built-in Audio

  • There is a audio bug in kernel 5.4 you may encounter on your Airtop

https://bugzilla.kernel.org/show_bug.cgi?id=205959

  • Symptoms: no sound from both Front and Rear analog audio outputs
  • To fix please expand and follow the below:
  • On Airtop in Linux both "Rear Audio" and "Front Audio" can not work in the same time
  • By default enabled "Rear Audio". If you want to switch to "Front Audio":
- Press [DEL] during boot to enter the BIOS settings
- BIOS -> Quick-Settings -> Rear/Front Audio -> [Front Audio] or [Rear Audio]
- Press [F4] Save and Exit
  • Open file /etc/default/grub for editing
  • Add "snd-intel-dspcfg.dsp_driver=1" to the end of kernel boot line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd-intel-dspcfg.dsp_driver=1"
  • Update grub settings
$ sudo update-grub2 
Sourcing file `/etc/default/grub'
..
done
$ sudo reboot
  • Test audio output
Menu -> Sound -> Output -> Built-in Audio Analog Stereo (it's not dynamic, nothing changes after plug/unplug headphones)
Click on "Test Sound", then on "Front Left" and "Front Right", check if it hear it from headphones

Intel video acceleration drivers

$ sudo apt update
$ sudo apt install va-driver-all mint-meta-codecs vainfo

Then run vainfo command, you should see list of supported profiles, for example on airtop3:

$ vainfo 
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_7
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.7 (libva 2.6.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 20.1.1 ()
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD

      VAProfileH264Main               :	VAEntrypointEncSliceLP
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointEncSliceLP

      VAProfileH264ConstrainedBaseline:	VAEntrypointEncSliceLP
      VAProfileVP8Version0_3          :	VAEntrypointVLD
      VAProfileHEVCMain               :	VAEntrypointVLD
      VAProfileHEVCMain10             :	VAEntrypointVLD
      VAProfileVP9Profile0            :	VAEntrypointVLD
      VAProfileVP9Profile2            :	VAEntrypointVLD

Nvidia graphics card drivers

$ 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
$ sudo reboot
  • Then run nvidia-smi command, you should see current NVIDIA card status:
$ watch -n1 nvidia-smi

Using both Intel and Nvidia graphics card

  • Want to connect up 7 displays simultaneously?
- Press [DEL] during boot to enter the BIOS settings
- Set "Chipset -> system Agent (SA) Configuration -> Graphics Configuration -> Internal Graphics"  to  [Enabled]
- Press [F4] to save and exit
- Boot to Linux Mint
- All connected displays will appear in the "Display" section

Noise mitigation on Nvidia graphics card

  • To reduce the noise need to set PowerMizer Mode to "Prefer Consistent Performance"
  • From GUI:
Menu -> NVIDIA X Server Settings -> PowerMizer -> Preferred Mode:  "Prefer Consistent Performance"
  • The same from command line:
$ nvidia-settings -a "[gpu:0]/GPUPowerMizerMode=3"
  • To make the setting permanent:
Menu -> Startup Applications -> "+" -> Custom command
 Name:    NVIDIA PowerMizer Settings
 Command: nvidia-settings -a "[gpu:0]/GPUPowerMizerMode=3"
 Comment: Set working mode "Prefer Consistent Performanse" to reduce noise

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

For example, Airtop3 with Quadro RTX 4000 is capable to play 4K UHD using CUDA video decoding without significant system load:

$ mpv -fs ~/Videos/jellyfish/jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv
 (+) Video --vid=1 (*) (hevc 3840x2160 29.970fps)
 (+) Audio --aid=1 (*) (truehd 6ch 48000Hz)
AO: [pulse] 48000Hz 5.1(side) 6ch s32
VO: [gpu] 3840x2160 yuv420p10
AV: 00:00:30 / 00:00:30 (99%) A-V:  0.000 Cache: 0.0s/2KB

Or the same content directly from the youtube:

$ mpv -fs https://www.youtube.com/watch?v=j4oBg8capW8
 (+) Video --vid=1 (*) (vp9 3840x2160 29.970fps)
 (+) Audio --aid=1 (*) (aac 2ch 44100Hz)
AO: [pulse] 44100Hz stereo 2ch float
VO: [gpu] 3840x2160 yuv420p
AV: 00:00:29 / 00:00:30 (99%) A-V:  0.000 Cache: 0.0s
