Ad-hoc changes via kscreen-doctor

# Inspect what's connected
kscreen-doctor -o

# Set mode (resolution.refresh)
kscreen-doctor output.DP-1.mode.3840x2160@60

# Set position (x,y)
kscreen-doctor output.DP-1.position.0,0
kscreen-doctor output.HDMI-A-1.position.3840,0

# Scale (1.0, 1.25, 1.5, 2.0…)
kscreen-doctor output.DP-1.scale.1.5

# Primary
kscreen-doctor output.DP-1.primary

# Enable / disable
kscreen-doctor output.HDMI-A-1.disable
kscreen-doctor output.HDMI-A-1.enable

# Rotation
kscreen-doctor output.DP-2.rotation.left

Multiple changes can be chained on one command line; kscreen-doctor applies them atomically.

Notes

• On Wayland, fractional scale is per-output; on X11 it's session-wide. Plasma 6 / Wayland is the assumed target.
• After applying, verify with kscreen-doctor -o.
• If a config doesn't stick across replug, the daemon's auto-snapshot is overriding — re-run apply, then disconnect-reconnect once so the daemon writes a new auto-snapshot for that output combo.
