Installation (from source)

1. Close Steam.

2. Clone the repository and install the script to user directory:

   $ git clone https://github.com/dreamer/roberta.git
   $ cd roberta
   $ make user-install
   

3. Start Steam.

Configuration

Settings for Roberta can be found in ~/.config/roberta.conf (or wherever XDG_CONFIG_HOME points to).

Additionally, per-game settings can be changed through variables set in the Steam client. For example, to force game to use your secondary screen, right-click your game in Steam Library, select Properties  General → Launch Options and set: LUX_USE_SCREEN=1 %command%.

You can use LUX_SCUMMVM_GAME=<game-identifier> to bypass the ScummVM launcher menu, and start the game right away, but it will hide important ScummVM launcher options. To open launcher menu press Ctrl+F5 and select Return to Launcher. The game-identifier value is one of section names in roberta_scummvm.ini file in the game installation directory.

Name	Values	Description
LUX_SCUMMVM_GAME	string	Set to the game identifier to run the specific game in a collection, bypassing the ScummVM launcher menu.
LUX_SCUMMVM_CMD	command	Use this command to run the game. Overrides value in scummvm.cmd setting.
LUX_USE_SCREEN	number	Set to the number of the screen, that you want the game to use. Overrides scummvm.fullscreenmode setting.
