These scripts are used on certain stations at the MiMa museum in Oberwolfach.
The scripts are installed (rsynced) into ~/bin via
install.sh
It is recommended to have ~/bin in the PATH, which is the default on most Linux distributions.
Exhibit start script names are prefixed with exhibt- followed by an identifier of that exhibit.
The script repeat-exhibit will restart the executable supplied as argument indefinitely, e.g.
repeat-exhibit exhibit-kiosk
will restart exhibit-kiosk if it exits for whatever reason.
All Exhibits can be stopped via
stop-exhibits
This includes the repeat-exhibit script and any process whose name starts with exhibit-.
The script hidecursor hides the cursor and starts another child process supplied as an argument.
When the child exits, the cursor will not be hidden anymore.
Sometimes the display used for development does not match the resolution used in production.
Assume your test display has a default resolution of 1920x1080 (FullHD), but in production, 3840x2160 (UHD) is used.
The command
fakeResolution 3840x2160
will allocatec a 3840x2160 frame buffer and will scale it down to 1920x1080.
If aspect ratios do not match, the image will be stretched.
This assumes that openbox is used as a window manager.
Each line added to ~/.config/openbox/autostart will be run in a shell.
If there is no & at the end of a line, execution will block until the corresponding process exits.
The scripts have been tested on Ubunt 18.04. Some additional tools are needed:
