Re: [beagleboard] Having Troubles Getting Started - Keyboard Config & Radios
Hi Justin,
I think the RDP issue with the keyboard layout you are having is a tightVNC
issue. Does the information in the following link describe what you are
experiencing? Do you absolutely need a graphical session to the beaglebone?

https://groups.google.com/forum/#!topic/beagleboard/YCiECD0fiII
Regarding wifi and bluetooth, you would need to manually set up the
networks using "connmanctl" which is already installed, or uninstall
"connmanctl" and opt for using the network-manager package which has a nice
cursors interface GUI for setting up ethernet or wifi networks. If you
install network-manager, run "nmtui" for the network manager text user
interface which is very nice.

For creating users, all Linux distributions will be very similar and you
can find lots of tutorials online such as this one:

WiFi/Bluetooth should work out of the box, running this should give us
some hints:
journalctl | grep wl18

[beagleboard] Having Troubles Getting Started - Keyboard Config & Radios
Hi,
I have just purchased a Seeed Beaglebone Green Wireless and am having
difficulties getting it up. I see the following problems -
* Remaining Problems*
1. RDP Keyboard layout is wrong
2. Add a new admin user ('Justin')
3. Enable WiFi
4. Enable Bluetooth
I have spent much more time than expected at this, see attached for
detailed description of procedure. I have found instructions for each
(#1-#4), but have failed to get these completed.
To start small, if possible, how can I correct #1? PuTTy works just fine
(Serial & SSH).
