G550DH + G450DH Framebuffer succes & directfb question.

Hi,

I managed to find a couple of matrox cards (G550 dual head AGP and a G450
dualhead PCI card), and decided to give it a go with ruby.
I did not succeed in setting up a working dualhead X environment yet
(although Xinerama works), but with framebuffer i have everything workingnow on kernel 2.6.5, even with modular matroxfb & fbcon drivers. There are
still a few issues (I think Helge also mentioned some of them before):

    * upon loading of the matroxfb drivers, all framebuffers show a garbled
      screen.
    * when loading fbcon, the garbled screen cleans up (mostly), but on the
      main console I see a big white rectangle. On none of the consoles I
      can see the login prompt, but it appears after pressing enter key :-)
    * when switching virtual console on the main console with F1-F6 keys,
      the framebuffer setup is somehow messed up and so the main console is
      also shown on the second head. Rerunning the matroxset commands does
      not help, but after rerunning my 'reset_matrox' script which also
      uses fbset to setup the framebuffers, everything works again.

Since the framebuffers are working so well, I decided to try some DirectFB
applications (would like to run freevo or mythtv on my TV and try
the XDirectFB server), however, they don't seem to like ruby because I keep
getting the following error with every application I try to start:

(!) DirectFB/FBDev/vt: FBIOGET_CON2FBMAP failed!
    --> Inappropriate ioctl for device

Is there anything I can do to further investigate? Perhaps I can patch
ruby to add a dummy IOCTL or patch directfb in some way that the IOCTL is
not needed anymore?
Should I take this to the directfb mailinglist, or is it a ruby problem?

The message reminds me of the old con2fbmap tool, which we don't need
anymore since ruby takes care of console to fb mapping :-)

Well, I'm very impressed with ruby's current state on matroxfb, so
good work guys!

Mark.

P.S.
Did any of you have any success setting up dual independent (accelerated) X
servers on the G550? I'm very interested to see your XF86Config!
