Re: Almost have VNC working, but black rectangle

The small black screen usually means that the desktop isn't running.
My Pi logs in automatically, and I have appended a line to ~.bashrc to do startx if X isn't already running
This doesn't sound right, you might be better off setting the boot option to "Desktop Autologin".

Re: Working with small HDMI display

You could use VNC for this. Assuming you're using the RealVNC server installed with raspbian, if you enable vnc from the raspberry Pi configuration app, what you get is a service mode server, designed to allow access to the console screen - your 5" screen this case. However, vnc can also be used to ...

Re: some of Demo programs in my Raspbian do not run

Assuming you're using the default RealVNC server in service mode (which is what you get when you enable vnc from raspi-config), there is an option to can enable that will let you see this.

If you go to the vnc options, troubleshooting page and enable experimental direct capture, that will do it.

Re: VNC Viewer disconnects from Raspberry Pi after 1 hour

Hi,

If you're using the RealVNC server, this is controlled by the "IdleTimeout" parameter on the server.
This is on the Expert page of the server options - the default is 1 hour, but you can set it to 0 for no timeout.

Re: Omxplayer doesn't display nothing

But even then it's unusable, because VNC cannot transfer at 50/60 Hz refresh in real time. Yes, you're limited by the network speed, but whether it's useful or not really depends on what you're using it for. For example, I regularly connect over VNC and run raspivid when I'm focusing my camera befo...

Re: Omxplayer doesn't display nothing

The output from omxplayer is displayed in a directly-rendered overlay, which isn't normally captured by vnc.

The RealVNC server can capture this though, provided you enable "experimental direct capture mode" on the troubleshooting page of the vnc server options.

Re: Tried to boot into command line mode, Pi won't connect to monitor and VNC displays black screen

The RealVNC service mode server normally requires the X desktop to be running, the black screen meaning that is unable to capture the screen. If you were to enable the "experimental direct capture mode", this will work even without X running. However, you may find it difficult to enable this now. Yo...
