gdm login default keyboard is in us while it should be in fr after adding ara locale
After adding arab locale to have a local arab keyboard i noticed that after a reboot us keyboard is selected in login by default, i have each time to select french again in language selection menu of login greeter.
once logged i get it in french on my desktop correctly.
i did search for a long time before posting here.
system is a debian buster.
Additionnally us and french virtual keyboard are working, when selecting french virtual keyboard i get a us mapping. arab setting is working on my other latptop on ubuntu 16.04.5 and unity, so i guess my current problem is debian gnome3.
