I got a 1366x768 monitor, which kernel option value of "vga=" should I use? I where i can find this option list? shortly, 16bit 1024x768 vga=317 32bit 1366x768 vga=?
Thanks.

boot with vga=ask, it'll scan and return a list of possible modes. Extended Vesa modes (such 720*, 1080*) tend to be graphics card BIOS specific.
Oh, I see. there is no 1366x768x32 vesa mode. So if I got a 16:9 monitor and I want to draw circle with framebuffer. It can never be a circle in display.

There is a distinction between the physical aspect ratio and the pixel aspect ratio. Most displays have square pixels now, so should still draw correctly depending on how the display shows that non-standard resolution (does it center the image or stretch it).
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?
