Devbox Display :1 Screenshot

When to use

Use when asked to capture what is visible in Kasm VNC session on devbox display :1.

Health check

bash

DISPLAY=:1 XAUTHORITY=$HOME/.Xauthority xset q >/dev/null && echo OK

If not OK, display/auth not ready.

Capture screenshot (.xwd baseline)

bash

TS=$(date +%Y%m%d-%H%M%S)
XWD="/tmp/display-1-${TS}.xwd"
DISPLAY=:1 XAUTHORITY=$HOME/.Xauthority \
  xwd -root -silent -display :1 -out "$XWD"
ls -lh "$XWD"

Convert to PNG (preferred)

Try first available method:

Method A: ImageMagick

bash

convert "$XWD" "${XWD%.xwd}.png"

Method B: Netpbm

bash

xwdtopnm "$XWD" | pnmtopng > "${XWD%.xwd}.png"

Method C: fallback

If converter tools unavailable, keep .xwd and send/share as-is.

Verify output

bash

PNG="${XWD%.xwd}.png"
[ -f "$PNG" ] && file "$PNG" && ls -lh "$PNG"

Optional send via OpenClaw (Discord)

bash

openclaw message send \
  --channel discord \
  --target 1464292705902395726 \
  --message "display :1 screenshot $(date -u +%Y-%m-%dT%H:%M:%SZ)" \
  --media "${XWD%.xwd}.png" \
  --json

If PNG conversion unavailable, use --media "$XWD".
