 # Terminal app
-## Graphical environment (Wayland, VNC)
-By installing Wayland compositor and VNC backend, you can enable graphical environment.
-One of the options is `sway`, `wayvnc` and `xwayland`(if necessary).
-
-```
-sudo apt install sway wayvnc xwayland
-WLR_BACKENDS=headless WLR_LIBINPUT_NO_DEVICES=1 sway
-WAYLAND_DISPLAY=wayland-1 wayvnc 0.0.0.0 # or use port forwarding
-```
-
-And then, connect to 192.168.0.2:5900(or localhost:5900) with arbitrary VNC client.
-Or, `novnc`(https://github.com/novnc/noVNC/releases). For `novnc` you need to install
-`novnc`, and run `<novnc_path>/utils/novnc_proxy`, and then connect to `http://192.168.0.2:6080/vnc.html`
-(or `localhost:6080` if port forwarding is enabled.)
-
-`weston` with VNC backend might be another option, but it isn't available in
-Debian package repository for bookworm.
+## Run GUI apps
+Execute `source enable_display` and then click Display button above to enable display feature.
+And then, go back to the terminal, and run GUI apps.
 
 ## Hardware acceleration
 If the file `/sdcard/linux/virglrenderer` exists on the device, it enables VirGL for VM.
