On installing the 173 driver via Synaptic package manager, I get:
E: /var/cache/apt/archives/nvidia-glx-173_173.14.12-1-0ubuntu4_i386.deb: trying to overwrite `/usr/lib/libGL.so.1', which is also in package libgl1-mesa-glx
this is slightly different, but seems related to the other errors I've met with.

Hmm…
Well, I'll verify that the fancy stuff is turned off, though I have no use for such things, and try to leave them off as a matter of course.
I tried moving back to version 173 of the NVidia driver, but it fails to install. For the .deb file, it claims a conflict with a file which is also a part of the xorg distro. The NVidia installer, and the envy application both fail as well, claiming an inability to compile the kernel. Looking at the nvidia log file, it says that it can't find a header file in the source… I'm at work and will give more specific details when I get home. I did find a discussion of the error listed in the log file which suggested I run a command with a -menuconfig option (sorry, can't recall the command). When I tried that, it failed as well.
Any additional hints will be met with great enthusiasm and appreciation.
I'll try 169 tonight, and post more details.
Thanks!

We've noticed this as well with the 177 drivers on Linux with some distributions. Your best bet is to go back to 173, or wait until 180 is released for Linux (and hope that it fixes the issues).
*Awesome* thanks. I'll give that a shot and confirm the results. Thanks!

I have been working with Houdini 9.5.303 on my laptop which is running Kubuntu Linux (32 bit Kernel revision 2.6.27-9) and an NVidia 8600 (Driver version 177.82). The graphics are quite broken, with window borders disappearing if the windo is smaller than the screen, and the upper right corner of the screen (about 2cmx1cm) just streaming random graphic data whenever the Houdini interface is trying to do anything. Pretty quickly, it crashes hard, requiring a power cycle.
Running XP under a VirtualBox virtual OS, the graphics are perfect, and no crash, but I *much* prefer never ever to boot windows, if I can avoid it.
Any configuration hints that will help Houdini run for me? I'll be most appreciative of any help, or pointers!
Thanks!

Technical Discussion » prim UV info from scatter SOp

Houdini version 7.0.214
OK… I'm doing a thing.
I have a lattice deformation:
- point based guide geometry (not lattice)
- rest is a locked SOp of a skull
- deformed is the skull animating
- source is from a scatter SOp on the rest geometry - a million points.
This is slow, and yields rippled imperfections in transforming the scattered points to the animating geometry (due presumably to the softness of the basis functions). So, I thought I would use the pointdist() function to find in the rest SOp the closest primitive, and primitive UVs - to each scattered point, and then use those coordinates to look up the deformed position in the animating geometry. I figure this should give3 me faster geometry with more perfect coplanarity with the deforming geometry.
The trouble is: pointdist() is too slow to run on a million scattered points. I thought it would be sensible to have the scatter distribute this info as the points are being scattered by cooking the pointdist() info into attributes on the source to the scatter, and have the scatter SOP interpolate the attributes at point creation time, rather than trying to suss it after the fact.
But: I cannot see how to precook this sort of information into the source to the scatter so the prim index attributes will be interpolated to the scattered points. How can I get the prim number, and prim UV coords for a piece of geometry stuffed back onto the points for interpolation at scatter time? I tried an attribcreate SOp with the pointdist() function relating the points of a SOp to the prims of the same SOp, but it hangs - possibly because of the ambiguity of which adjacent prim should be reflected in the return.
I'd half expect to have the scatter SOp with an option to stuff index info from the source prim into the points during the cook.
Can anyone think of a good way to do this?
Many thanks.
