description	Build, launch, and drive pgNimbus headlessly to verify a change end-to-end (Xvfb + xdotool + ImageMagick screenshots against a local Postgres).

Verifying pgNimbus changes

The full sandbox bootstrap (apt packages, Xvfb, Postgres seed, launch command) lives in CLAUDE.md → "Bootstrapping a fresh Linux/CI sandbox" — follow it verbatim; it works as written. Extras learned from real runs:

• Connection dialog vs. main window: launching without PGNIMBUS_CONN opens ConnectionDialog (the login screen); setting it skips straight to MainWindow. Pick per what you're verifying.
• The dialog is 640×680, centered on the 1280×800 Xvfb screen → it spans roughly x 320–960, y 60–740. Screenshot first (DISPLAY=:99 import -window root shot.png), read the PNG to find exact control coordinates, then drive with xdotool mousemove <x> <y> click 1 / xdotool type ... / xdotool key ctrl+a Delete.
• Run the app in the background under timeout 180 dotnet run --project PgNimbus.App --no-build so one launch survives several drive/screenshot Bash calls.
• SELECT count(*) FROM pg_stat_activity WHERE application_name='pgNimbus' is a handy probe for leaked/pooled connections.
• Ubuntu 24.04's apt Postgres is 16.x; service postgresql start + ALTER USER postgres PASSWORD 'postgres' is all the seed the connection dialog needs.
