Instructions for setting up touch display with Raspberry Pi running Arch linux. This is a brand-new release using DSI display port.

Follow instruction here to setup, and also Video Instruction here There is a official mechanical drawing in case you needed. Remember to make a full system upgrade to enable the touch screen driver (in my case, both for Arch Linus or Rasbian) if you have not done so already.

Go to application /Accessories /Keyboard Note: The system font was messed up after installing cellwirter. It was restored after add following fonts (refer Fonts in window title crashing xfce4-title).

1. Autostart X at login, refer to here

   1 2 3 4

   #~/.bash_profile exec startxfce4

   update!! following is needed instead of above for SSH to work.

   1 2 3

   [[ -z $DISPLAY && $XDG_VTNR -le 3 ]] && exec startxfce4

2. Automatic login to virtual consol, refer to here run following command,

   1 2 3

   systemctl edit getty@tty1

   and, past contents, and save

   1 2 3 4 5

   [Service] ExecStart= ExecStart=-/usr/bin/agetty --autologin username --noclear %I 38400 linux

   Notes: The file is located in etc/systemd/system/getty\@tty1.service.d autologin.conf or override.conf

3. reboot
4. Notes:

   1. SSH -X stopped working after this, but SSH -Y works. Update: fixed with following:

      1 2 3 4 5

      $ ssh user@host $ sudo su # xauth merge /home/user/.Xauthority

   2. Auto login to virtual never gives me problem. While auto start x did fail to start. Here is what I did, SSH into raspberrypi from another PC.
   3. go to ~/.bash_profile and un-comment the line for auto-x

   4. Reset default target to boot into, reference here

      1 2 3

      sudo systemctl set-default -f multi-user.target

      This should fix the startxfce4 failure issue.

   5. Redo step 2 and step 3.
   6. Here is a good info from gentoo site.

Some screenshots of the system.
