I just got my PI's , one model B+ I bought with an sd card with domoticz pre-installed and a PI 2, The PI 2 became available just after I ordered the older PI

I started with the domoticz pi, and immediately had some problems.
- I cannot set the keyboard layout to Belgian
- startx does not work, I get a message that it does not exist
For the keyboard layout, I tried several things but the layout remains qwerty instead of azerty
In raspi-config I tried several keyboard laytouts nl-be, fr-be, be but no good.
I also tried sudo nano /etc/default/keyboard and change the layout to be and fr but no good either
I tried the same things after doing apt-get update/upgrade
When I put the domoticz sd cart in the PI 2, it shows a colourfull screen, but it does not boot,
do you need another distro for the PI 2 ?
Best rgds, Marc
