Lubuntu Users Group: (Sorry - I initially sent this from the wrong e-mail address) To mount my NFS drive on my local client systems, I needed something to get ask the user for root privilege. On Lubuntu 16.04, I used gksu, but on Lubuntu 18.04, that package appears to be unavailable. So in its place, I installed lxqt-sudo, and used that. However, after installing that, a number of applications no longer have their normal Gnome look-and-feel, but instead, have a dark look, and take up a huge (much more than necessary) amount of screen real-estate. The applications I'm having this problem with, are: qjackctl qsynth qmidiroute Does anyone know how I can change them back to their former Gnome look-and-feel (or even explain what has happened)? The strange thing is, on some of my 18.04 systems, this didn't happen - those applications still have their usual Gnome look-and-feel.

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. I found this question on AskUbuntu: https://askubuntu.com/questions/716714/change-qt5-theme tl;dr Use either of these: lxqt-config qt5ct -- Regards -- Lubuntu-users mailing list Lubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/lubuntu-users

I am using LXDE. I performed the apt install qt5-gtk-platformtheme statement. It indicated the latest version of it was already installed, and the newest version.

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.
