I am on galliumos which is based on ubuntu 18.04. This spotify issue is weird because I get this error after I launch it once and close on a fresh login “[1124/211758.542810:FATAL:gpu_data_manager_impl_private.cc(442)] GPU process isn’t usable. Goodbye.” Then when I get this error I fix it by running this command line argument --no-zygote.
Here is the source where I found this fix
