displaylinkfb is a new branch written by Jaya Kumar, targeted at embedded via defio and no in-kernel shadow framebuffer, which uses the standard fbdev X servers.displaylink-mod is a updated branch of the udlfb driver by the same author (Roberto).udlfb is the original displaylink kernel framebuffer driver, without dynamic mode support and a few minor features, but fully functional and present in kernel versions 2.6.31 and later, and enabled by default in some recent distros (Ubuntu 9.10).Or use the driver shipped with kernel 2.6.38 or more recent.Kernel DisplayLink Driver from Google Code.Standard X driver updated to use ?DisplayLink devices. Current Driver Locations, culled from this thread.Savvy people would be able to get other distros running, but it can be a slog. Most people in the ?DisplayLink community running X are on an older version of Ubuntu (9.04), and some on certain versions of ?RedHat. And it's also possible to configure X and standard X applications to run on udlfb - but that part is still very distro dependent today. It's still very much under development, but it's possible to write custom applications to it today (or to libdlo user mode library itself, bypassing udlfb). A fully open source (GPL) driver which supports all ?DisplayLink devices to date (all DL1xx devices) is in the mainline of the Linux 2.6.38 kernel, and can be compiled as a module for certain older kernels.
