A Run Down Of VT Switching On Linux

David Herrmann, the student developer working on DRM Render Nodes this summer and has been a longtime proponent of killing the Linux kernel console, has written at length about VT (virtual terminal) switching on Linux systems.

Herrmann has worked on projects like a DRM terminal emulator, a frame-buffer log driver, and numerous other related projects in his long-term goal to kill off the Linux kernel console (CONFIG_VT).

For those wanting to learn more about the Linux VT system, David has written several extensive blog posts this weekend to detail the current implementation:

- How VT switching works.

- Session management on Linux.

- Sane session switching.
