# Batocera Display Shaders, bezels, and display mode — everything about how the picture looks. Assumes the connection pattern, `batocera.conf`/configgen model, and verify loop from `batocera-ops`. Because display changes are visual, the `batocera-ops` **remote verify loop** (ES HTTP API launch + `batocera-screenshot`) is your primary tool here: never declare a shader or bezel "working" from the config alone — launch it and look. ## Shaders Shaders are assigned per-system (or per-game) in `batocera.conf`. Two key mechanisms and the traps around each. ### `shaderset` resolves against TWO search paths `<system>.shaderset=<name>` is a **folder-name lookup** resolved against both: 1. `/userdata/shaders/configs/<name>/` (user-installed) 2. `/usr/share/batocera/shaders/configs/<name>/` (system-bundled) Checking only one path is enough to wrongly declare a preset invalid. Some built-in names are aliases that resolve to a preset deep under `/usr/share/batocera/shaders/`. Before concluding a `shaderset` value is dead: ```bash SSHB "find /userdata/shaders /usr/share/batocera/shaders -maxdepth 3 -iname '<name>*'" ``` And read the launch log for the shader actually used on the last launch — it is authoritative: ```bash SSHB "grep -i 'set-shader\|shader' /userdata/system/logs/es_launch_stdout.log | tail" ``` ### Two shader keys: `shaderset` vs `-renderer.shader` - `<system>.shaderset=<name>` — a Batocera shaderset folder (may bundle bezel art, e.g. Koko-AIO/Duimon presets). -...
