If you mean that you would like DSL to display on two monitors, I would guess that you would have to use XFree86 - I never tried this however...

| There are some cool features of the framebuffer devices, in that you can give generic options to the kernel at bootup-time, including options specific to a particular framebuffer device. These are: video=xxx:off - disable probing for a particular framebuffer device video=map:octal-number - maps the virtual consoles (VCs) to framebuffer (FB) devices video=map:01 will map VC0 to FB0, VC1 to FB1, VC2 to FB0, VC3 to FB1.. video=map:0132 will map VC0 to FB0, VC1 to FB1, VC2 to FB3, VC4 to FB2, VC5 to FB0.. |
PS: Smth strange with consoles: switching by ctrl-alt-
f1 - booting information, commands not writes, if push ctrl+c f2 console shutdown X;
f2 - X;
f3 - nothing, not work;
f4 - nothing, not work.
Who it solve?

when i write in /boot/grub/menu.lstin kernel boot param:
video=map:01
and reboot.
Kernel outs debug information
It seems that i must recofigure kernel. If so, would you tell me how? Thank you!

From the framebuffer howto, multihead section:| Quote |
14.6 What hardware is supported? Most video cards assume they will be the only one in the system and are permanently set with the addressing of the primary display adapter. There are a few exceptions. * Matrox cards: This includes Matrox Millennium, Matrox Millennium II, Matrox Mystique, Matrox Mystique 220, Matrox Productiva G100, Matrox Mystique G200, Matrox Millennium G200 and Matrox Marvel G200 video cards * MDA: This includes monochrome Hercules graphics adapter among others. This for text only second head support. Note: it's only the second adapter that has to be one of the above. |
I've done it with full X, and I think you can do it with TinyX too. So boot in console mode (runlevel 2)
and run

I think he doesn't want X, but only console fb VT's on a multihead setup, i.e. with /dev/fb*Maybe you can use fbset? Or maybe you need to install another driver (check which fb's are installed) and there seems to be CONFIG_FB_MATROX_MULTIHEAD in dsl.config
Or you could try replacing it with directfb or something...
but I've really only done multihead setups with X.

It doesn't work But it is not that i whant.I need frame buffer. We use directFB libraries. And i want that first console was on fb0(first monitor), and fb1 on second console(second monitor).
ps: sorry for mistakes

Like I quoted from the howto, normal fb multihead is only possible with Matrox or Hercules cards..Don't know about DirectFB though...
