Hi guys, VCV Rack’s official noob here, for some unknown reason VCV keeps crashing. I’m running ubuntu 18.04.5. I ran htop to see if the problem was my cpu but it does not seem to be the problem. It has never crashed like this before I have restarted it like 3 times but it is the same result. I am not running many modules or effects either. Thank you for your time.
I do not know what the problem is, I may just be dumb 
.
Please post your log.txt after a crash. It is almost impossible to help on a crash without any information.
How do u do this?
VCV freezes a few times then a popup window appears saying it has crashed.
Sorry i’d prefer not to show you my log.txt as it contains my name and such.
I’m no expert but I dont see any errors.
However it does say this:
[95.140 fatal src/main.cpp:45] Fatal signal 6. Stack trace:
Is this helpful?
Not really
Sorry 
Search & replace that with something else then.

Could you put that in code tags?
What hardware are you running?
Sorry i’m not very good with code or technical stuff. To be honest I don’t even know what a code tag is lol.
I’m running 10gb ram, Intel Sandybridge CPU, 4 cores, no graphics card (built in), on a 10 yr old Packard Bell laptop. That’s all I know. I am also running Ubuntu 18.04.5.
Try removing your settings-v1.json file in ~/.Rack directory.
I find on linux that you can configure rack in such a way that it won’t boot.
If that doesn’t work you can remove the autosave-v1.json file from the same directory. If you do that, though, you’ll lose any unsaved work.
This should allow you to start rack.
I believe I have fixed the problem. I had Mindmeld mix master saved on my template. I removed this module and it seems to be working fine. However this could just be coincidence. Thank you all for your time.
