Changes
* Disconnect the installation media and reboot.
* Login using previously selected username and password.
== 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 package for Airtop or Airtop2:
<pre>
$ product_name=$(cat /sys/class/dmi/id/product_name)
$ wget http://www.fit-pc2.com/download/airtop/$product_name/airtop-fpsvc_systemd.deb
$ 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.
</pre>
* Note, the package adds "acpi_enforce_resources=lax" string to the kernel boot line
* Reboot the Airtop after installation
* Now you can navigate through menus between multiple screens of the I<sup>3</sup>M that display system information, temperatures, power consumption and notifications
== Intel video acceleration graphic drivers ==
<pre>
$ 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 $nvidia_driver vdpauinfo mesa-vdpau-drivers vdpau-va-driver --install-recommends
</pre>
Then run vdpauinfo nvidia-smi command, you should see list of supported profiles, for example on Airtop2current NVIDIA card status:<pre>$ watch -n1 nvidia-smiThu Jul 12 02:31:03 2018 +-----------------------------------------------------------------------------+| NVIDIA-SMI 390.48 Driver Version: 390.48 ||-------------------------------+----------------------+----------------------+| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.
