Hi Damien,
the current version of nyx still produces event notices like these when run as a user that is neither root nor the tor user ([sic] for the missing spaces):
10:33:26 [NYX_NOTICE] We were unable to use any of your system's resolvers to get tor's connections.This is fine, but means that the connections page will be empty. This isusually permissions related so if you would like to fix this then run nyx withthe same user as tor (ie, "sudo -u <tor user> nyx"). 10:33:11 [NYX_NOTICE] Unable to query connections with netstat, trying lsof 10:32:53 [NYX_NOTICE] Unable to query connections with proc, trying netstat
In a discussion here some weeks ago, it was pointed out to me that it is in fact *not* recommended to use "sudo <tor-user>" to run nyx.
