Triple head freeze-up issue

[T3tra]

Greetings Devs and Users,

[system info at bottom of post]

I have a triple head setup at home, and another at work. Connecting from home to work I can expand my work desktop across all 3 local monitors, and the performance is amazing – thanks for that!

The issue I’m seeing is that if I collapse the fullscreen over multiple monitors, do things locally, then expand it again, it will not fully expand over the local frame (sides fit, but top and bottom are no longer masked, or ‘letterboxed’) into my taller monitors at home. But that’s not the real problem. The problem is I cannot do anything with the expanded session now – it’s locked. ctl-alt-0 is also inop, and the client must be killed outside of !NM from a shell.

It’s completely reproducible – happens every time, and I’m pretty sure you don’t want it to behave that way 🙂 I know I dont! triple head is probably not tested as rigorously as dual monitor setups. I can do whatever testing you need to help get a handle on this.

Thanks!

Christopher

Hi Christopher, thank you for the report. We agree, it’s not the right behaviour! 🙂 Could you kindly compress the most recent directory $HOME/.nx/R-* while the client is frozen, and send it to forum[at]nomachine[dot]com. We didn’t reproduce the issue in our labs, so your help would be great to speed up the investigation.
