Hydrogen stopped running (KXStudio 14.04.2)

Up until this evening Hydrogen was running fine. Then I tried running it alongside Rosegarden and QSampler and it (hydrogen) crashed. Whenever I try to run it I see the splash-screen then nothing, except 1 xrun gets logged.


I'm running it in KXStudio 14.04.2 64-bit with 3.13.0-101-lowlatency kernel (the default one that's installed with KXStudio) I'm not sure which version of Hydrogen because I can't run it to find out.


I have uninstalled and purged and then reinstalled it (apt-get) and have the latest version according to that.

Any help would be appreciated, thanks.

To get what version you're using, you can either look into your package manager (muon/synaptic if I remember correctly), or use the command line with : hydrogen -v

To try to find why Hydrogen isn't launching, you can try to start it from the command line and read at the messages displayed there.


To try to correct the issue, you can move/rename the /home/your_user_name/.hydrogen/ folder (which contains your users data) to reinitialize it, and relaunch Hydrogen.

Hope that helps.

Okay, if anybody else has a similar problem, this is how I sorted it out:

I renamed (just because deleting it would be irreversible) the hydrogen.conf in /home/username/.hydrogen.

Hey presto! Hydrogen is working again.
