The /dev/fb is no problem, I'd just have to subclass rfb::Framebuffer. The real
work is to convert keyboard input from /dev/tty... to X Windows (RFB) keycodes
and to get mouse events from /dev/mouse or gpm. I didn't have much time to
check this out yet. Any ideas?
Btw, I'd use a linux 2.4.x kernel for that, they've got more framebuffer
drivers.
So, whats needed?
- Kernel with /dev/fb and network support - linux 2.4
- /sbin/init binary and a small sh-script - simpleinit?
- a very small shell - ?
- a very small libc (not glibc, it's too large) - ?
- insmod / ifconfig / route (to configure the nic)
- loadkeys (not everybody's got an english keyboard)
- gpm (mouse driver)
- a vnc client supporting /dev/fb, /dev/tty and gpm
Did I miss anything?
