Crashes on Ubuntu Noble

[madarexxx]

• I confirm that this is an issue rather than a question.

Hi!

Bug report

I am running Hyperion.NG on Ubuntu 24.04 (Noble) with WLED-over-USB hardware. Have not used for a while and now it is crashing on start with some nasty errors on start. Have checked GitHub issues, found this one: #1807

I have tried updating to latest nightly build from Ubuntu repo. Pull request #1807 should already have been included in my nightly build, but Hyperion still crashes, so I fill new bug.

Steps to reproduce

1. Install Hyperion NG on Ubuntu 24.04
2. Set your leds and screen capture
3. Enable smoothing or black bar detection (cannot figure yet what exactly is causing trouble)
4. Restart Hyperion hyperiond -d --service

What is expected?

Should restart and work fine :)

What is actually happening?

Hyperion crashes with following errors in log (cropped to significant parts):

Segmentation fault (core dumped)

Workaround

1. Set up everything, disable all effects and smoothing and black bar detection.
2. Backup settings DB
3. Start Hyperion.
4. Re-enable smoothing and black bar detection

If you forgot to disable effects and/or Hyperion had crashed you should restore DB from backup and re-enable settings.

Hi @madarexxx

Thanks for sharing your finding.

As the nightly build might have issues, could you test with #1860

How to test see: https://docs.hyperion-project.org/user/advanced/Testing.html#linux

In case it still crashes, could you share the full log when you start from the command line?
Plus export the configuration via hyperiond --exportConfig . and share the json file, please?

I guess I found something.... I expect your DISPLAY is not set....and then I see that the XCB Grabber fails discovery...
