I used my linux (Ubuntu Studio) to flash the sd card. I installed via apt a program called rpi-imager, ran rpi-imager, Selected the Pi Device: Raspberry Pi 3, Selected the Operating System (to be installed): Raspberry Pi OS Lite (64-bit), and Selected a 32GB sd Card. I edited some options, one is to add a user right away. Once that was completed I booted the pi from the newly created sd card and ran the list of commands:<\/p>\n\n\n\n
2. setup Pi<\/p>\n\n\n\n
sudo apt update && sudo apt upgrade
sudo apt install xinit remmina<\/code><\/pre>\n\n\n\nsudo apt install xinit<\/code><\/pre>\n\n\n\nThen to make sure everything is operating correctly run:<\/p>\n\n\n\n
xinit remmina<\/code><\/pre>\n\n\n\nIf everything seemed to load, and your looking at just a remmina window, then it worked. Click the plus to add your Remote Desktop Server and attempt to connect. Once it is working and you can connect successfully, then lets proceed. <\/p>\n\n\n\n
3. Create User and permissions<\/p>\n\n\n\n
sudo useradd -m -s \/bin\/bash thinclient<\/code><\/pre>\n\n\n\nsudo usermod -a -G video,tty,input,render,audio thinclient<\/code><\/pre>\n\n\n\n(added) sudo chmod g+rw \/dev\/tty0 \/dev\/tty1<\/code><\/pre>\n\n\n\nMake sure this is set correctly, however, more on it in a bit.<\/p>\n\n\n\n
sudo dpkg-reconfigure xserver=xorg-legacy<\/code><\/pre>\n\n\n\nselect Anybody or Console Users Only – hit enter<\/p>\n\n\n\n
4. setup users bashrc file<\/p>\n\n\n\n
sudo nano \/home\/thinclient\/.bashrc<\/code><\/pre>\n\n\n\nThen scroll to the bottom and enter these lines:<\/p>\n\n\n\n
sleep 2\nxinit \/usr\/bin\/remmina --enable-fullscreen -- vt1\nsleep 2 \nexit<\/code><\/pre>\n\n\n\nMy file:<\/p>\n\n\n\n
sleep 2
xinit \/usr\/bin\/remmina --enable-fullscreen -- vt1
sleep 2
exit<\/code><\/pre>\n\n\n\nCtrl + X to save and exit the file.<\/p>\n\n\n\n
5. Enable Console Auto-Login<\/p>\n\n\n\n
sudo raspi-config<\/code><\/pre>\n\n\n\nSelect System Options > Boot \/ Auto Login
Select Console Autologin<\/p>\n\n\n\n
Exit the utility and reboot the pi<\/p>\n\n\n\n
sudo reboot now<\/code><\/pre>\n\n\n\n5.1 Enable Auto-Login with user, thinclient<\/p>\n\n\n\n
raspi-config defaults to auto-login in your original user account, so we must change that.<\/code><\/pre>\n\n\n\nsudo nano \/ect\/systemd\/system\/getty@tty1.service.d\/autologin.conf<\/code><\/pre>\n\n\n\nthen we look for the line starting with ExecStart=<\/p>\n\n\n\n
ExecStart=-\/sbin\/agetty –autologin (original user) –noclear %I $TERM<\/p>\n\n\n\n
Change that line to read:<\/p>\n\n\n\n
ExecStart=-\/sbin\/agetty --autologin thinclient --noclear %I $TERM<\/code><\/pre>\n\n\n\nSave and Close that file as before.<\/p>\n\n\n\n
Now you should be able to reboot your pi and have it automatically load remmina, and now you basically have a functioning thin client.<\/p>\n\n\n
