| The support is in Digital UNIX, but the newer code can always be found in
the Open3D kit. I'd have them install Open3D and see if the problem goes
away.
Also, are they running XDM and CDE window manager? CDE does not support a
second screen.

| Thanks Irene,
They are not running CDE. I'll try the Open3D kit to see if it helps
(is it really later than 3.2g?).

| While Open3D may have shipped prior to 3.2g, no new code for that DDX has been
checked in for a VERY long time (> 1 year!). I know Open3D has fixed quite
a few bugs in that time. All the base OS has is a shadow copy of the DDX
code. Open3D has the master copy and thus a set of newer fixes.

| We just tried Open3D - it made no difference - same symptoms.

| Does anyone have a 255/233 who can try this with V3.2g?

| I have an update to this call. The customer has now installed Open3D and
after rebuilding the kernel (which he'd forgotten to do) and rebooting it
now works. Here's the wierd bit though. After a fresh install, the
message written to xdm-errors (as John said in his base note) is:
Screen 0 ZLXp2-EV4 Revision #2 8 bits/pixel 2097152 bytes
Server scanline padding disagrees with ROM, adjusting
Screen 1 ZLXp2-EV4 Revision #0 8 bits/pixel 16777216 bytes
^ ^
------These are different
But after installing Open3D and rebuilding the kernel, etc, the message
changes to:
Screen 0 ZLXp2-EV4 Revision #2 8 bits/pixel 2097152 bytes
Screen 1 ZLXp2-EV4 Revision #2 8 bits/pixel 2097152 bytes
As it should be. It looks to me like something is wrong in the installation
or implementation for the ZLXp2-EV4 in the base V3.2g product. Even though
it says screen 1 is a ZLXp2-EV4 it displays the memory size of a ZLXp2-EV5
(PBXGB-CA). And Open3D is required to overwrite the duff code and put it
right.
Just to make sure, I got him to check the jumper settings on both cards.
Screen 0 has VGA enabled and screen 1 disabled, which is correct. And
both cards have the "Alias" jumpers open (disabled) which is also correct
(the ZLXp2-EV5 is the opposite - Alias jumpers are close [enabled]).
So this is definately a bug in the V3.2g base product. Time for an
IPMT?

| 3 months later...
The customer has started to compare the performance with and without
the Open3D kit installed (they only loaded the drvers). They claim
(and I have no reason to disbelieve them right now) that the graphics
were faster without Open3D installed. They make no explicit use of
Open3D as such.
Is this likely to be true?
Do the driver bugfixes make it into the base OS in DU V4.0(anything)?
