ANSYS Workbench on "Uncertified" Linux Distros

hsr

Hi everybody,

i tried to run ANSYS Workbench on Debian or one of its kick-offs ([X][K]Ubuntu) and always end up with the situation that Workbench starts nicely, but when starting "Geometry" the applications hangs up showing a white rectangle in the upper left corner within the ANSYS window, starting "Meshing" ends up in a segfault.

The workstation has a NVIDIA graphic card (Quadro4 XGL 900) This situation seems to be caused by some issues resulting from Debians integration of the GLX-extension into the X-server (same results with XFree86 and X.org). When using the "nv"-driver or not loading the "glx"-Module Workbench's Geometry-Module starts (almost) perfectly. Since the GLX extension is missing, the 3D-Object-Window is empty (and Xlib is complaining about the missing GLX extension on stderr).

Right now I'm working on CentOS 4.5 with no problems, but I'm still trying to get the Workbench up and running on a Debian Linux. I checked Debian with the same nvidia-drivers (96.43.01) as on CentOS. As I remember some weeks before the official Debian 4.0 release (early 2007), Workbench worked with an etch installation (until I applied an dist-upgrade). Since then I haven't succeeded in bringing life back to Workbench on Debian&Co. Maybe it's worth to try installing backport libraries of the X-server.

In the official ANSYS forum I found some advices, but none of it worked:

- before starting Workbench ulimit -s unlimited

- using an environment variable setenv USEWBANSYS_GL true

Has someone spotted the problem with Workbench vs. X+GLX on Debian?

P.S.: Workbench runs on (uncertified by Ansys) Slackware 11.0 and distros basing on that one like VectorLinux 5.8 also tried others like PCLinuxOS, Knoppix etc. but they were also disappointing
