I had some issues with RD only opening in windowed fullscreen on startup.
This fix is currently working for me. wayland was most of the issue..

Step 1: Switch to X11

Check Current Session

Run:

bash

CopyEdit

echo $XDG_SESSION_TYPE

If it says wayland, continue below.

Switch to X11 (GUI Method)

  1. Log out of your Ubuntu session.
  2. At the login screen (GDM), click your username.
  3. Before entering your password:
  • Click the gear icon :gear: in the lower-right corner.
  • Select “Ubuntu on Xorg” (this is X11).
  1. Log in.

Verify

Open a terminal and confirm:

bash

CopyEdit

echo $XDG_SESSION_TYPE

It should now say x11.

Step 2: Install xdotool

bash

CopyEdit

sudo apt install xdotool

Step 3: Script to Launch RealDash and Toggle Fullscreen

bash

CopyEdit

#!/usr/bin/env bash

# Start RealDash
realdash &

# Wait for the window to appear
sleep 5

# Get window ID (adjust title match if needed)
WIN_ID=$(xdotool search --name "RealDash" | head -n 1)

# Focus the window
xdotool windowactivate "$WIN_ID"

# Send Super+F4
xdotool key Super_L+F4

Save as:

bash

CopyEdit

nano ~/realdash_fullscreen.sh

Then:

bash

CopyEdit

chmod +x ~/realdash_fullscreen.sh

Step 4 (Optional): Run Script on Login

To auto-run the script after login:

  1. Open Startup Applications (gnome-session-properties)
  2. Click Add
  • Name: RealDash Fullscreen
  • Command: /home/YOURUSERNAME/realdash_fullscreen.sh
  • Comment: Launch and fullscreen RealDash
  1. Click Add and close

You’re Done

  • Launch automatically
  • Be focused
  • Go fullscreen via Super + F4
