# ~/.xinitrc — start your X session without a window manager

# 1. Set environment variables (optional)
# export PATH="$HOME/bin:$PATH"

# 2. Start xbindkeys for Alt+Tab switching
xbindkeys &

# 3. (Optional) Start other background utilities if you need them
# xsetroot -solid black &
# unclutter &       # hide mouse when idle
# xset -dpms s off  # disable screen blanking

# 4. Start your main application(s)
# Example: start an xterm and keep it open
xterm &

# 5. Wait for all background processes
wait


#"The ampersand (&) after xbindkeys lets it run in the background so the rest of .xinitrc continues.

#The wait at the end keeps X running until all programs you started close — this is the usual pattern for bare X setups.

#If your main app is full-screen (e.g., a kiosk, GUI app, or game), you can just launch that last, e.g.:

#/path/to/myapp

# and omit wait.

###Oher version of xinitrc
#!/bin/sh
# ~/.xinitrc — minimal bare-X setup
# POSIX-compliant

# --- 1. Environment setup (optional) ---
# export PATH="$HOME/bin:$PATH"

# --- 2. Background helpers ---
# Start keybindings (Alt+Tab cycling)
xbindkeys &

# Set a simple root window background color
xsetroot -solid black &

# Optional: hide cursor when idle
# unclutter &

# --- 3. Main applications ---
# Start all main apps in background
firefox &
xterm &
gedit &

# Add more main apps here if needed:
# chromium &
# mpv &

# --- 4. Wait for all main apps to exit ---
# This ensures X will close only after all main apps are closed
wait
# or exec mpv then closing mpv will kill X and apps in the background?
