For those guys who use the preconfigured wheezy image here some beginners tipps which might help you save some time:
The login is “pi” and the password is “raspberrypi” (or only “raspberry” not sure anymore ^^)
IF you have an european keyboard make sure you do not enter “raspberrzpi”… this kept me busy longer than it should have -.-
once you’ve logged in enter “sudo raspi-config” to configure the Pi (like, set GUi to start at boot) or just enter “startx” to start the GUi
Thats about all the difficulties i had while setting up the image 🙂
Tought it might help someone else save some time and googling.
