VESA mode with 1366x768 monitor

you mean that  i should change the image ratio by the program i write?
That's a solution.

another question:

I find if I run into "init level 5" with the x running, then I can't using
ctrl+alt+f2 to switch to tty2(just a black bright screen).
when I need to use framebuffer i have to change the /etc/inittab to level 3
and restart.

Is that because 1366x768 is managed by graphic card and the tty console is
managed by framebuffer device which can not be showed in the 16:9 ratio with
1366x768?
