====  Laptop Setup ====

The specific software setup for the image download is in the [[image-download-station|Image Download Station setup]].


==== WIFI =====
If Wifi isn't working, first check if the firmware file can be loaded! 

  dmesg | grep rtw_pci
In Ubuntu 18.04 the firmware for rtw8822 wifi adapter (ASUS TUF FX505DV Laptop) isn't included in linux-firmware ubuntu deb package! So after a Kernel update it can be necessary to fetch it again and copy it to the lib folder.

  git clone git://git.kernel.org/pub/scm/linux/kernel/firmware/linux-firmware.git
  cp ./linux-firmware/rtw88/rtw8822c_wow_fw.bin /lib/firmware/rtw88/


=== eduroam ===

Eduroam does not work with the default wpasupplicant 2.6 version. I have made a backport of wpasupplicant 2.9 from Ubuntu 19.10. 

{{ ::wpasupplicant_2.9-1ubuntu2_amd64.zip | wpasupplicant package 2.9 }}

You need to install that package. Please download from this wiki and unzip it. 

<code>
sudo apt install libnl-route-3-200
sudo dpkg -i wpasupplicant_2.9-1ubuntu2_amd64.deb
</code>

Check that the wpa supplicant service is running with

<code>
sudo systemctl status wpa_supplicant.service
</code>

In the Wifi Settings for eduroam choose in the "security" settings

  * Security: WPA & WPA2 Enterprise
  * Authentication: Tunneled TLS
  * Anonymous identity: eduroam@hs-augsburg.de
  * Check "No CA certificate is required"
  * Inner Authentication: PAP
  * Username: YOURUSERNAME@hs-augsburg.de
  * Password: YOURPASSWORD

=== crrcsim ===

crrcsim is the flight simulator. The Taranis RC can be connected to the laptop via USB. Install the crrcsim package

<code>
sudo apt install crrcsim
</code>

Add the following to the .profile

<code>
export SDL_JOYSTICK_DEVICE=/dev/input/js0
</code>

To start the simulator run

<code>
crrcsim
</code>
