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:




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.

I have been unable to determine why it is okay on some of my systems, 
and not on other systems.

Dear Aere,

The C4C Lubuntu 18.04 ReSpin now uses pkexec [https://www.freedesktop.org/software/polkit/docs/0.015/pkexec.1.html] in place of gksu. By utilizing
          the method put forth by and the policy files created by Allen Guarnes [https://www.allenguarnes.com/technology/resolving-the-missing-gksu-command-in-ubuntu-18-04/] you should be able to do what you want and have everything look just the same as it did. In ebery case I've tried, I've been able to replace gksu with pkexec. For example, the command gksu pcmanfm can be replaced with pkexec pcmanfm.
Eric--Thank you,God bless you,Computers4Christianshttp://computers4christians.org
