I’m trying to get a Debian 8.8 (Jessie) install on a Dragonboard 410c configured so I can use either VNC or X11 for remote connections. I’m currently accessing the board via ssh for development and have no problems with this setup but will need a GUI environment in the near future. I know I can simply connect the board to a monitor using HDMI and add a keyboard and mouse but this wastes a lot of desk space and screws up my dual monitor setup as one is then dedicated to the 410c.
So far I’ve installed the full desktop version of Linaro Debian 8.8 using the SD card method then fully upgraded it, configured it for ssh access and have successfully connected to it from Microsoft Visual Studio 2015 and 2017 in Linux development mode and built a fairly sophisticated project.
I’m stuck trying to configure lightdm to provide a remote desktop either via tightvncserver or straight X11. I have been able to configure the system to the point where I can successfully execute single programs such as xcalc or xclock and have them connect to the xserver running on my Windows 10 workstation.
I’ve also been able to configure the VNC support in lightdm such that it executes Xvnc when the VNC client on my workstation establishes a connection but as soon as I finish entering the VNC connection password Xvnc dies and the VNC client displays a message indicating the display geometry is incorrect and then sits waiting for a reconnect.
If I configure VNC to not use a connection password the same behavior is seen with the exception that I’m not prompted for a password.
BTW: All these gyrations are happening when np HDMI connection to a monitor exists, could this be why the X server thinks the display geometry is wrong?
Any help with this would be greatly appreciated!!!
