1.1. About Backstreet Ruby/ Ruby

Backstreet Ruby is a kernel patch for the Linux kernel. It is a back port to Linux-2.4 of the Ruby kernel tree, which is developed by the Linux Console Project. The aim of the Linux Console developers is to enhance and reorganize the input, the console and the framebuffer subsystems in the Linux kernel, so they can work independent from each other and to allow multi-desktop operation. All this is done in the Ruby kernel tree which is based on the development Linux-2.5 kernel. The new Input subsystem and the new Framebuffer layer are already integrated in Linux-2.5 kernel, but as the main developer of the Linux Console Project, James Simmons, is too busy with completing the rewrite of the framebuffer layer in Linux-2.5, the multi-desktop operation will not be integrated in the next stable Linux kernel (Linux-2.6).

So Backstreet Ruby brings to the current stable Linux kernel (Linux-2.4) the enhanced input subsystem and the ability to use multiple graphic cards and multiple keyboards independently, in order to make multiple local XFree users on a single PC system possible.

You can have multiple independent graphic cards and multiple independent mice, but in order for multiple users to interact with the system, they do need independent keyboards as well. Multiple independent keyboards is the feature that Linux-2.4 (and in the future Linux-2.6) lacks, and this is what Backstreet Ruby adds to the stable Linux kernel Linux-2.4.

The entire work on back porting Ruby to Linux-2.4 is done by Aivils Stoss.

Aivils got recently his hands on Ruby, and now Ruby is fully functional[1] too, so if you prefer the Linux-2.6 kernel you might use Ruby instead of Linux-2.4 + Backstreet Ruby.

Visit his web site for more information on the patch itself, on the current status, how to build a kernel using his patch or how to build modified XFree86 server.

Notes

[1]

All the features in Backstreet Ruby are included ( "/proc " interface & hot-plugging, video hack, ...), support for Framebuffer devices, support for single Framebuffer console which takes over the VGA console (support for multiple independent Framebuffer consoles is not yet implemented)
