Multiple video cards

I have an AGP Mach128 card and a PCI Voodoo3 3000 card in my system. In
my /etc/system/config/graphics_modes file I spliced a line from each
cards set onto a single line - removing the stuff after the ;# on each
line. It looked like
io-graphics -g1024x768 …rage128 stuff ; io-graphics -g1024x768
-o1024 …banshee stuff

It sort of works; both screens light up, the mouse moves back and forth
OK. But if I open an app on the second screen, I can use it OK, but when
I hit close (or exit), that portion of the screen is never redrawn. The
window looks good, but nothing on it works, and pidin can’t find the
app. It went away and left its window behind.

A similar config works fine with Photon 1.14 with both QNX4.25 and
oemNTO2.11beta, by the way.

Any hints would be appreciated…

Thanks, Phil Olynyk

Sounds like whatever is drawing your background…isn’t.
Try dragging a window around on screen 2.

Someone else had a similar problem, and the solution was to not run bkgdmgr in the photon
script. Or you can slay it off whenever you start photon.

Slaying bkgdmgr does the trick! Now I lose the picture, but it wasn’t as nice as the moon in
the oem Nto collection anyway.
Any guesses as to why slaying the manager makes things work? Don’t answer, Dilbert! It was
a rhetorical question, not an existential question.

I trust this will be fixed somewhere along the way from patchA to patchZ…

Thanks much -
