fresh install ubuntu 24.04 and VCV 2.5.2 - nothing happens

when I double click on rack nothing happens. no user directory exists, so no log file.

I remember not being able to get VCV to run by clicking the icon in the file browser on my linux machine. You may need to run VCV Rack from the command line. If you cd into the directory and run ./Rack does it start up?

The manual might help: Installing & Running - VCV Rack Manual

You can create a bash alias that does this and bind it to a keyboard shortcut so you don’t have to open a terminal every time you want to run VCV. That’s what I do. Something like:

alias launch_vcv="cd /path/to/VCV && ./Rack"

Let me know if this was helpful.

I’m only a beginner at Linux, but the one thing that comes to my mind is that you may want to check if the file is set to “executable”.

good suggestion. it says illegal instruction (core dumped)

Do you have a really old CPU? Some googling hints that it may be an incompatibility with older CPU architectures. That is a bit beyond my understanding though.

support said my cpu (amd e300) doesnt support sse4.2 (it supports sse4A) so I think this is the main problem
