@igi Canonical Could you please explain (best in the bug description) which and how rtc permissions should be set?

[Bug 677931] Re: Muse does not start
Salut Fabrice, Hi igi, In my case, Ubuntu 10.04 up to date and Muse 1.1 same problem: Muse won't start unless Jack is started. Looks like Muse isn't getting enough precision from the rtc. Running Muse as root allows it of course. Otherwise, it wants Jack for its timer. To allow enough rtc precision to underprivileged mode, type: $ sudo sh -c echo 1024 /proc/sys/dev/hpet/max-user-freq To be able to run Muse, the system should allow users to set rtc frequencies up to 1024 Hz. -- Muse does not start https://bugs.launchpad.net/bugs/677931 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Oops, sorry, I had left Jack running :-( The command does not set the required permission. But I think the reasoning is at least half correct. When will we have comment update?

[Bug 677931] Re: Muse does not start
/proc/sys/dev/rtc/max-user-freq is the variable which should be set to 1024 According to http://manpages.ubuntu.com/manpages/lucid/en/man4/rtc.4.html it should exist but it does not. This seems to be the frequencies the kernel has been compiled for: $ grep CONFIG_HZ /boot/config-`uname -r` # CONFIG_HZ_100 is not set CONFIG_HZ_250=y # CONFIG_HZ_300 is not set # CONFIG_HZ_1000 is not set CONFIG_HZ=250 -- Muse does not start https://bugs.launchpad.net/bugs/677931 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 677931] Re: Muse does not start
@André: I did not change the max-user-freq setting, since it was 64 per default, as specified. Anyway I have rechecked my trace (in the description of this bug), and I have seen I had permission errors for rtc. Trying to run both jack and muse as root, muse is properly starting. So I guess the solution is to properly set permissions for rtc folder when muse has to access it. ** Changed in: muse (Ubuntu) Status: New = Confirmed -- Muse does not start https://bugs.launchpad.net/bugs/677931 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
