Re: [Lmuse-user] muse rtc permisions etc (again)

[james m. <ja...@jw...>]

Ok, upon 'cat /dev/rtc' cat just waits and otherwise does nothing.

There seems to be no running processes which have opened it from 'lsof
/dev/rtc'

I am running a kernel with a 1000hz sys timer also.

Guess it's one of those things I should just relax about then.

Muse was a little happier though when I did 'sudo muse' but that
approach seems a bit of a step backwards these days and had the added
drawback of not finding the running jackd.

Sorry to be a pain, I have this strange almost masochistic insistence
upon building complex software from source instead of relying on pkg
managers to do it for me!

James.
