LXDM permissions problems on login

Post by decomp »

Hi all,

Myself and others are having problems with LXDM not properly setting user permissions on login - I think. We are using audio jackd2 for audio production, and are having problems getting the permissions to unlock memory and use realtime.

In order to use realtime audio processing with the program jackd, the user must me a member if the group 'audio' and have the following permissions set in /etc/security/limits.d/audio.conf:

@audio - rtprio 99
@audio - memlock unlimited
@audio - nice -10

the problem is that even though these permissions are set, the user is still not getting access.
the ulimit command reports:

Code: Select all

$ ulimit -r -l
real-time priority              (-r) 0
max locked memory       (kbytes, -l) 64
And applications run as the user cannot unlock memory and use real time. Commands run as sudo, however, are able to use real time.

You can see a discussion about this problem here. http://www.linuxmusicians.com/viewtopic.php?f=27&t=2979

This user has replaced lxdm with slim to resolve the issue. I would like to file a bug report so this can be fixed. Can anyone tell me what other information is required for the bug report?
