This may be a simple question, but a quick look at the documentation and forum didn’t readily reveal the answer to me.

When you launch a GUI application that uses NoVNC, the card where you can launch the NoVNC session shows “Compression” and “Quality” sliders. Is there a way to set the default values for those in your configuration (e.g. form.yml or script.sh.erb)?

Thanks!

No, it looks like they’re hard coded defaults. I’ve created this ticket upstream.

That said - choices are being cached locally in your local, so while you’re talking about defaults, the system will save your choices for the next time.

Thanks Jeff. I’m glad I wasn’t just being dumb.
