More dual Monitor Woes (QNX 6)

I’m trying to get dual monitors set up in QNX 4 (for legacy support,
I’ll also be asking this for QNX 6)

I have two Radeon 7000 boards and my graphics-modes uses:

io-graphics -g1024x768x32 -dldevg-vesabios.so -I0
-d0x1002,0x5159;io-graphics -g1024x768x32 -o1024,0 -dldevg-vesabios.so
-I1 -d0x1002,0x5159;#1024,768,32,100,0D,dual_vesa - unaccelerated driver
for VESA 2.00 compliant adapters

Now when I first start photon only one screen comes up. If I switch to
another mode and switch back the second screen comes up but the first
screen doesn’t seem to be able to display HTML widgets (i.e. helpviewer
window is blank on one screen but not the other.

Any pointers or suggestions at all?

I’m using 6.2.1B

I’ve tried this line:
io-graphics -g1024x768x32 -dldevg-radeon.so -I0 -d0x1002,0x5159
-R60;io-graphics -g1024x768x32 -o1024,0 -dldevg-radeon.so -I1
-d0x1002,0x5159 -R60;#1024,768,32,100,0CBDr,dual_radeon - ATI Radeon

But without success. At least the VESA one worked after being switched
out and back in.

Have you tried using the Radeon driver (devg-radeon.so) instead
of devg-vesabios.so?

That fixed it so that the VESA drivers come up correctly when the
machine is powered up.

Thank you Very Much!

As an aside, the Radeon drivers still don’t work and the helpviewer
still doesn’t work on the primary screen.

There may be a problem with io-graphics starting its internal font
server on the secondary card. Check ‘sloginfo’ for any error messages.

Hi

the problem with helpviewer/voyager etc not working, is that they use
PtOSContainers for their data (offscreen dubblebuffering), and that does
not currently work with multiple monitors.
I suspect this is one of the reasons that multimonitors arn’t supported
by QSSL, You should be able to get this working by hacking the
executable (vserver/vserver.file) using spatch to use PtContainer
instead of PtOSContainer.
Also there is a option in voyager preferences to make the PtWebClient
widget not use doublebuffering.
