Hello, I have installed Ubuntu on my mac but I receive this message when trying to run SDK:

[dix] Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!
unrecognised device identifier!
(EE) config/hal: NewInputDeviceRequest failed (2)
unrecognised device identifier!
(EE) config/hal: NewInputDeviceRequest failed (2)
unrecognised device identifier!
(EE) config/hal: NewInputDeviceRequest failed (2)

and I think is a font missing, Ihave searched fixes even here but no one seems to have an understandable solutoon for this.

I have never used linux for more than a day and I always install the lates just to test around, I have come with a variety of failures installing this SDK and can't fix it to this point.

Thank you.

You should be able to run the SDK despite those errors. Just ignore them.
