[SOLVED] jack

scarrs · 09-13-2013, 05:44 PM

hello all
I have a little problem. I am running slackware 14 and installed jack, qjackctl and all the dependencies. I can run qjackctl successfully as root but not as my user.

I am a musician and am running the program guitarix (awesome software) and would love to be able to run this program as a normal user.

please help

Where did you put the binary? Normally it should go in /usr/bin. Assuming that's where it is, then post the output for this:

Code:

ls -l /usr/bin/qjackctl

If it's not in /usr/bin (or perhaps, /bin) then find out where it is and check on the permissions using the command suggested above.

This page suggests that you use

Code:

setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/qjackctl

See if that works.

Reading the page again it seems you also need to set jackd to have the same capabilities.

So you also need

Code:

setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/jackd

But if that doesn't work, you can remove the capabilities with

Code:

setcap -r /usr/bin/qjackctl
setcap -r /usr/bin/jackd

I tried both of those commands and I can't get qjackctl running as a user. I reverted the qjackctl line and qjackctl starts again but fails to run when I try to start the server. qjackctl still continues to run perfectly as the root user. I am so close, don't give up guys. I need a little help with one.

Perhaps the people in the Slackware section would be able to help you out more. If you think it'll help solve your problem then use the report button and ask for your thread to be moved.

Moved: This thread is more suitable in Slackware and has been moved accordingly to help your thread/question get the exposure it deserves.

I reinstalled slackware and installed all my programs again. setting those 2 commands provides the help I was looking for.
