Hi, everybody,

I need your help!

1. How can I switch to another virtual terminal by
normal user process?
VT_ACTIVATE ioctl can only be called by processes
having root rights.

2. When I switch away from and again back to the
virtual terminal where I do frame buffer drawing,
screen content is destroyed and replaced by original
console text?
How can I avoid this problem?

3. What is FBIOPUT_CON2FBMAP? What does it do?

4. How can I do flipping between primary frame and
secondary frame?
