Comment 3 for bug 1880418

it appears that if I use the following:
   >lxqt-sudo lxrandr,
the configuration will save.

Sadly the man page for lxrandr provides no real assistance and after some investigating came across the lxqt-sudo information in the LUBUNTU manual. And the xorg randr via thinkwiki, I was able to assemble the information needed. Suggestion to provide a notification when lxrandr is used via the gui to run it manually in the other fashion. Additionally, there is nothing in the LUBUNTU manual that explains the lxranr interface.

As well the lxqt-sudo write up in the manual could provide an expansion as to when it could be/should be used.

I would extrapolate that bug 1860918 could possible be resolved using lxqt-sudo if the end use knew what to use with this. I did not find a quick 'about' button to identify the mouse and keyboard config app's name.
