Well, I assume you haven't installed the fbset-utility.
You can check that! First type:
fbset
and if you get an error like
"command not found"
then you have to install the fbset-utility.

Type: "export GGI_DEBUG=255" and run your app.

An debugging output, you have to send it to this ML, so that we can help
you to track your problem down...

No. You have to use the fbdev-target. If you want to use the
svgalib-target, you must disable/unload your VESAfb driver. And also you
have to check, if svgalib supports your graphic card.
If svgalib supports it, then there is a configuration
error and/or a bug. If not, then the VGA-modes should work.
Generally the X-target should always work.
If you want to do that, and your VESAfb-driver is loaded you have to use
XGGI. If your VESAfb-driver is not loaded, you have to use a normal
x-server...

The file you mean is /etc/fb.modes

As I said above, you have to install the fbset-utility.

Ah ... you love high portability?

see above.

All drivers, which don't use any BIOS calls in realmode...

That's right.

It's in the ggi-snapshots. You can use it, _if_ there is a driver for your
card...
