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.

Yes I did that worked first few times and then stops and I cant see nothing on the monitor just black screen
Thank you for your help
Before I could see loading everything before it went to desktop now nothing

Please help
Thank you

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

[kiskaprince]

sudo raspi-config

This is very useful command
Thank you for that link
All working now
Just curious if is it possible to installwin10 core lot on this revpi core?

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.

Thank you
One more thing
When I connect to a computer by micro USB it doesn't get recognize as a drive
I just doesn't show
Is there a command to run to be able to see it after?

[dirk]

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.

Yes thank you
But the rpiboot doesnt recognize it either it shows waiting forever
Maybe I am missing something?
Thanks
