I attached the slides from my kernel summit presentation. The major change is that Linus does not want a new VT state. Instead we should open a new VT, switch it to VT_GRAPHICS, and then refuse to acknowledge VT swap requests. Dave Airlie did another presentation on mode setting and suspend/resume. The simple overview: goal is to get rid of the current VT swap system but replace it with something that looks just like it. To do this the console is split into two halves. 1) kernel console - it is as simple as possible and always guaranteed to work. It is simpler than current fbconsole. It automatically uses whatever mode is set on the monitor. There is only one kernel console - no VTs. 2) user console - implements your normal VTs. Fully accelerated, supports Unicode, etc. No one was really against restructuring the consoles. There was support for a console that always works even when something like X is running.
I am really interested in this, and want to help (with code, once architectural issues are solved). But there is a question: How should applications that currently rely upon a kernel VT system being present (e.g. Xorg, MPlayer, SDL) be modified? (I mean, is there any proposed API for hunting for a free userspace VC?) -- Alexander E.
