I received NO replies to my first query. I've also tried on various newsgroups.
Does anyone have a clue at all?
On my Digital Alphastation 500/400, with the
Powerstorm 4D50T 3D accelerator, Open3D is installed, and the
server configuration file claims to be loading the PEX/PHIGS extension.
GLX and OpenGL absolutely do work, and at very satisfactory performance.
I have Digital Unix 4.0b, and recently installed the BAS0004 patches (which did
not help my problem)
However, the PEX extension doesn't display in xdpyinfo:
number of extensions: 26
Adobe-DPS-Extension
BIG-REQUESTS
DEC-Direct-Render
DEC-E3-SPECIAL
DEC-GLX
DEC-PEER-GLX
DEC-XTRAP
DECStereo
DOUBLE-BUFFER
DPMS
DPSExtension
GLX
Keyboard-Management-Extension
MIT-SCREEN-SAVER
MIT-SHM
MIT-SUNDRY-NONSTANDARD
Multi-Buffering
SHAPE
SYNC
Shared-Memory Transport
XC-MISC
XIE
XInputExtension
XKEYBOARD
XTEST
XVideo
Here is the appropriate (I believe) section of my Xserver.conf:

I have checked that the libraries listed under _dec_PEX exist:
-rw-r--r-- 1 root bin 24576 Mar 17 12:51
/usr/shlib/X11/lib_dec_PEX.so
-rw-r--r-- 1 root bin 221184 Mar 17 12:51
/usr/shlib/X11/lib_dec_3dlib.so
-rw-r--r-- 1 root bin 851968 Mar 17 12:51
/usr/shlib/X11/lib_dec_x3d_pex.so
I couldn't find anything in release notes that indicate that PEX is not
supported on the 4D50T.
Does anyone know the magic incantation I need? AVS, which currently uses PEX
comes up in software rendering only, and although the rendering is quite
adequate, it is certainly not at hardware speed!
Thanks for any help.
