No, better not: It's dangerous, if your patch is buggy and pd runs wild. I only use -rt during performances. Regarding patco's problem with realtime mode: "chmod +s" is not a good idea as it's a potentially big security hole opening up your system for all kind of local exploits. And it's not necessary, if your system is set up correctly. Correctly means, that you need a current libpam (Ubuntustudio has it) and you need to set up /etc/security/limits.conf accordingly. Accordingly means, have something like this in it: @audio - nice -10 @audio - rtprio 99 @audio - memlock -1 and your user needs to be in group "audio" then. If even then, Pd's realtime mode isn't activated, then something much deeper is wrong.
