I'm assuming you're using the xorg.conf that Chris Debenham provided a
couple posts back, and that lspci shows 00:02:00 -> intel card and
02:09:00 -> nvidia card, as in another post. In that case, for the
"Screen 2" test you get:

(II) I810: Driver for Intel Integrated Graphics Chipsets: i810, i810-dc100,
       i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G, E7221 (i915),
       915GM, 945G, 945GM
(II) Primary Device is: PCI 02:09:0
(--) Chipset i815 found

AHA!! and later on we see:

(II) I810(0): initializing int10
(II) I810(0): VESA BIOS detected
(II) I810(0): VESA VBE Version 3.0
(II) I810(0): VESA VBE Total Mem: 4096 kB
(II) I810(0): VESA VBE OEM: NVidia
(II) I810(0): VESA VBE OEM Software Rev: 2.5
(II) I810(0): VESA VBE OEM Vendor: NVidia Corporation
(II) I810(0): VESA VBE OEM Product: Riva TNT
(II) I810(0): VESA VBE OEM Product Rev: Chip Rev B1

which is fubar and all sorts of wrong!! the i810 driver should be
binding to device 00:02:00 (the intel card), but it's grabbing the
primary device instead.

I recommend you upgrade your Xorg server to the newest suse xorg
package you can get your hands on, and see if starting screen 2 still
starts the i810 driver on the riva card. If this bug ain't fixed in
later versions, someone more knowledgable than me needs to look at why
that happens in the i810 driver code.

Your attachments are inline and so it's hard to tell which is which.
Proper mime attachments, or better yet posting links to files is
