Antix 17.4.1 Qjackctl not working

[Member jono]

Live-booted 17.4.1 freezes desktop after starting qjackctl. Only mouse cursor moves but no actions by clicking possible. I had tested previous Antix versions: same behaviour.

ok, thanks for the tip!

.
interpreted as a tip because…
if your intent was a “help request”, you would have provided details useful toward troublshooting, right?

It’s a known problem ,just search for qjackctl in the search-box.
Solution could be to compile it yourself from github , with the ./configure option ,
mentioned in the github-issues-thread( scroll down )
Maybe.

The only help I could find is:
https://github.com/dnschneid/crouton/wiki/Access-audio-hardware-directly-(ALSA,-JACK)
where it specifies settings for qjackctrl:
“I found jack2 to be quite finicky with DBUS issues, so make sure you uncheck Enable DBUS Interface in Qjackctrl -> Setup -> Misc”

Maybe this will help.

confirmed antiX frugaler, since 2019

AntiX 17.4.1 and MX 18.1 use the same version of qjackctl (0.4.4-1) but on MX it works.

Analysis with ldd:

AntiX loads additional libraries which likely cause the desktop freezing.

I conclude that qjackctl works differently on AntiX and MX – but it works correctly on MX!

OK. I got it installed and it doesn’t hang.
Following this issue-thread on github they mention the problem is related to the window-manager and the solution is to configure it with
./configure –disable-xunique

https://github.com/rncbc/qjackctl/issues/13

So here’s what I did.
Installed with the package-installer ” QT5 Dev Enviroment “(under developement)
Installed with synaptic ” libjack-jackd2-dev ”

From jack on my system is installed
jack
jackd
jackd2
libjack-jackd2-0

Downloaded the qjackctl-0.5.6.tar.gz from this side
https://qjackctl.sourceforge.io/

Extracted the tar.gz, then went into the extracted folder qjackctl-0.5.6
There opened a terminal and typed
./configure --disable-xunique

When done
make

afterwards
sudo make install

The qjackctl.desktop will get installed under /usr/local/share/applications and can be moved as a desktop-icon to the desktop.
To start it from terminal run /usr/local/bin/qjackctl

Probably the next version of qjackctl 0.5.7 will have a fix for the problem, but when the fixed version will appear in debian remains open.Even sid version is still 0.5.0

I am not experienced with qjackctl but it doesn’t freeze the desktop and seems running good.

I was able to build a qjackctl with your instructions. But qjackctl starts with an error because it can’t find the audio ports.
Look at the added screenshot from what I’m getting when using qjackctl under MX.
Under AntiX there is nothing to choose from for the audio-ports. I only get fixed entries “default” for the Input- and Output-Device.

Yes, by default there is “default” as devices, but can you not type in there ? I can.
From the FAQ
http://jackaudio.org/faq/device_naming.html

I hope there will soon someone else participate here with more experience than mine with qjackctl
