This is unfortunately dead it seems. Any alternative? I couldn't find anything myself.

vulkan has indeed also been problematic. It's been making houdini more unstable. I also reverted back to openGL.

I never got it to be remotely usuable on ubuntu. The UI flickers all the time on mouse over. 2s after installing the latest LTS, I revert back to x11.

19.5.435, with any drivers for 4090 on linux and vellum hangs when using a vellum pressure constraint. The only fix that works is disabling the GPU for openCL at the cost of performance of course. Bummer.

19.0.430 daily build is no longer crashing for me like the production build. Redshift 3.0.59 works fine as well.

But 18.5 remains an issue, production or latest daily.

I got 18.5 and 19 to start, but it's a bit of a roll of the dice. At least 50% of the time it will result in a crash. I'll post some of the crash reports tomorrow.

So, I have all the libs mentioned above installed on a fresh 21.10. as mention it does work, but it takes a few tries sometime to get houdini launched. Simply launching it from the terminal. I get various type of crash ranging from no message at all to this :

Same issue for 18.5, but that hot fix doesn't work for me.

Are you getting the munmap_chunk(): invalid pointer error or some other ?
Because the LD_PRELOAD trick should take care of that one ,even for 18.5, I've just tested it.

Can, I ask. Are you on a fresh install of ubuntu 20.10? or did you upgrade from a previously installed version

EDIT: I got it to work, thanks for the help!!!

Same issue for 18.5, but that hot fix doesn't work for me.

You can no longer access the hidden param in H18.0.597 on for this feature.

Since it's deprecated, what the new method!?!
