Hi, you cannot start the graphical desktop on a SSH terminal session. To use the graphical desktop you have the following options
1) connect direct: via a HDMI monitor, login and then type "startx"
2) connect remote: configure boot to graphical desktop via WebStatus
Then you may configure remote access via TeamViewer, VNC, etc.

Hi, the TeamViewer credentials are not the same as on the sticker on the RevPi. Please have a look at the tutorial how to setup TeamViewer. You may also have a look at the video tutorial Tutorial 24 – TeamViewer-RevPi Beta. It is available with English subtitles.
If you have problems with the graphical desktop then the TeamViewer installation will not fix this problem. So there is an error which seams to be related to permissions

Code: Select all

Fatal server error: (EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)
I am no expert for this topic but here I found a possible solution for this problem.
Maybe the user "pi" has to be added to the user group "tty":

Code: Select all

sudo usermod -a -G tty pi

Hi, good to hear that you have solved your problems. Currently we don't have plans to support Windows on the RevPi. Have a look at this discussion: Windows 10 IoT core.

Hi, yes there are some steps to take, have a look at this tutorial: Saving and installing images.
And if you prefer watching instead of reading, have a look at: Video Tutorial 01 – Creation of an image.
