I currently using Sparkylinux 3.3.1 (Razor-Qt).
I can't find any menu that allow me to add another keymap (Default is English US-UTF-8).
Now I want to add thai keymap but I can't find any menu that allow me to.
In Language me nu I added th item in the list already.
And can't add any kaymap from Keyboard Layout Settings menu.
Why you can't add thai keymap?
You have to choose Other-> then Thai.
After rebooting should be working.
