** Description changed:

- Posting here what gnome says about porting to wayland, and their tests:
- 
- GNOME Applications under Wayland
- GTK+ has a Wayland backend. If it was enabled at compile-time, you can run a GTK+ application under Wayland simply by:
- 
- GDK_BACKEND=wayland gnome-calculator
- Applications that use Clutter or clutter-gtk also need the Clutter Wayland backend enabled:
- 
- GDK_BACKEND=wayland CLUTTER_BACKEND=wayland cheese
- 
- https://wiki.gnome.org/Initiatives/Wayland/Applications
- 
- ======> so hope the settings are well set at compile time; maybe a
- rebuilt to get sure all apps are ok.

  Steps to reproduce:
  1. Install Ubuntu 17.10
  2. Install backintime-qt4 or gparted application from above list (full may be acquired from https://codesearch.debian.net/search?q=pkexec+filetype%3Adesktop+path%3A*%2Fapplications%2F*&perpkg=1&page=4 )
  3a. Try to launch backintime-qt4 from shortcut "Back In Time (root)" (located in /usr/share/applications/backintime-qt4-root.desktop, it uses pkexec
  ($ cat /usr/share/applications/backintime-qt4-root.desktop | grep Exec
  Exec=pkexec backintime-qt4)
  3b. Try to launch Gparted from shortcut "GParted" (located in /usr/share/applications/gparted.desktop, it uses gparted-pkexec)
  4a.1. Back In Time does not start from GUI.
  4a.2. Back In Time shows error message in console:
  4b. gparted-pkexec does not start, reports error
  $ gparted-pkexec

  Expected results:
  * backintime-qt4 may be run as root
  
  Actual results:
  * unable to run backintime-qt4 as root
  
  Workaround:
  * setting "xhost +si:localuser:root" helps.
