Running "simple" example results in garbled cubes being drawn in simulator

(1/2) > >>

Hi LaserFolks,

Using an HP laptop I tried many Linux distros until I found one where I could solve the dependencies and run on my hardware. In my case it was Ubuntu 14.04 64 bit. When I follow the Openlase and Jack configuration on the Openlase wiki, and run the "simple" example. I get a large morphing "scribble" drawing at 60fps instead of the cubes I should be seeing. I cannot find an error in what I have done but I am obviously missing something. I'd appreciate some guidance so I can graduate from the simulator to using the LaserSharks I bought.  Thank you all for your time.

I develop/test with Linux Mint. This is based off the Ubuntu codebase and your 14.04 64 bit should be fine.

To dive into this:
- Am I correct to assume you are running Ubuntu directly on the hardware vs through something like VirtualBox or VMWare Player?

-Can you run the lasershark_stdin app and circlemaker app successfully?

-Can you take a screenshot of your patchbay configuration inside of qjackctl (with all components expanded)?

Thank you.
Answers:
1. Ubuntu is running on hardware, no VM
2. yes, your stdin and circlemaker cooperate to draw a circle on my wall.
3. screenshot attached

Hmm, I haven't seen this before. Immediately this makes me think there is a Jack configuration issue, or a problem in how OpenLase was configured or compiled.

Thanks for the screenshot. Based on this it looks like your Jack patchbay looks ok.

Your Jack patchbay looks ok. Can you take a screenshot of the jack "Setup..." window too? Specifically I'll be interested to see if you have the driver set to "dummy" or an actual audio interface.

Ok, no smoking gun yet, here's the setup screenshot:
