Feature #216
Updated by Hammel over 11 years ago
I have a Lilliput USB monitor that would work great in the trailer. To get this to work I need to "follow these steps":http://karuppuswamy.com/wordpress/2012/08/17/lilliput-displaylink-usb-monitor-um-70-17e902a9-with-raspberry-pi-on-raspbian/.
The xorg.conf should open this up as a second display, for display purposes only such as with temperature and sensor displays. The S90UI init script should handle that, if it finds a /dev/fb1 for the USB display.
The DisplayLink driver is not currently enabled in the PiBox kernel. It's unclear if there is a "special X.org driver":http://karuppuswamy.com/wordpress/2011/04/11/lilliput-displaylink-usb-monitor-um-70-17e902a9-with-qnap-ts-110-on-debian-linux-armel/ or if the "fbdev driver":https://wiki.archlinux.org/index.php/DisplayLink is sufficient. The fbdev driver is in Buildroot but 2013.02 has 0.4.2 and the "latest is 1.0.5":http://xorg.freedesktop.org/releases/individual/driver/.
