I am using the Xfce desktop environment in Garuda Linux Lite, its good but the keyboard layout keeps changing whenever the desktop environment loads or whenever the computer restarts.
I have no idea how to fix this issue and it is really annoying please help...
Just go to settings and keyboard layouts and move your desired keyboard layout to the top and save settings. I hope it works 
Also you can try setting it via Garuda settings manager 
Im having the same issue, but i want to keep it as English (US), it's going back to Australian (The one i chose when i installed it), everytime i reboot. Can you please explain to me where you changed it to solve it? That's how mine look like at this moment, and how i want to keep it. Cheer!
What's in etc/locale.conf? Might be the fix, too...
Here's what i got.
LANG=pt_BR.UTF-8
LC_ADDRESS=pt_BR.UTF-8
LC_IDENTIFICATION=pt_BR.UTF-8
LC_MEASUREMENT=pt_BR.UTF-8
LC_MONETARY=pt_BR.UTF-8
LC_NAME=pt_BR.UTF-8
LC_NUMERIC=pt_BR.UTF-8
LC_PAPER=pt_BR.UTF-8
LC_TELEPHONE=pt_BR.UTF-8
LC_TIME=pt_BR.UTF-8
Looks like what you set once - it should be persistent. You can edit it in that file to be what you want - or access its settings a number of other ways. Here is a quick rundown from the web..
which should help if you don't have it from the Archwiki or elsewhere
