If you are using LXDE then, installing lxqt-sudo probably installed some more things, and changed a Qt setting.

I launched qjackctl, and it still has the strange, dark, look-and-feel. I couldn't find anything in /usr/share/applications/ that resembled QT settings, or KDE settings. In Synaptic Package Manager, I searched for "kde-settings", "kdesettings", "qt-settings", and "qtsettings", but none of those searches found anything. Is there something I could install that would allow me to change the settings? Hi Aere, I am not 100% sure what needs to be installed, but I found an answer. The main thing you need to do is change the Qt theme to use the Qt GTK+ engine. I am sure there is a way to change the theme from the terminal (like with GTK), but I don't use Qt as much as FLTK/GTK toolkits.

At least it is worth trying. If it works without changing the looks of things, you can make a function and/or a desktop file for it, to make it easier to use (and to avoid forgetting the -H), particularly if other people are to use it for setting up the KeyMusician system.
