Re: Wireless VNC Connectivity

VNC works fine over WiFi! That is the way I access my Pi Zeroes.

I suspect that your problem is network related in getting the WiFi established between the client and targeted machines. The network address for the VNC link will be different in such an environment.

Re: Black screen while raspberry is on

You have almost certainly messed up your Pi installation!

The repository you added is for software designed to run on Intel compatible CPUs (as are typically used in PCs or Macs). Such software is not compatible with the ARM processor that is on your Pi.

Re: problems at formating the sd

The one you want is the one labelled ‘boot’ as it is the first partition on the SD card. Writing the image will overwrite any partitions already existing but you want to make sure you start from the beginning of the card. You will probably find Etcher as being easier to use than win32diskimaher. It ...

Re: Can I desolder the micro USB port in the pi zero and replace with usb c

This is not possible. USB-C ports have far more pins than the USB-2 ports used on the Raspberry Pi.

That plugin is for running on an Intel compatible processor, while the Pi uses an ARM processor which is not compatible with it.

Re: RDP: question from a beginner guy

It's better to use RealVNC as it is faster, more secure, easiest to use.
I think that this is not an option if the requirement is to connect to a Windows system that is set up for RDP connections as realVNC does not support the RDP protocol (or it did not when I last checked)

Re: The Raspberry Pi Desktop OS 64 bit

Normally the only reason for going to a 64-bit version of an OS is so that you can use more RAM. That is not a consideration with the Pi since the hardware is limited to 1GB RAM this is not a reason for going to a 64-bit OS. There is normally no performance benefit for going to 64-bit, and 64-bit pr...

Re: power multiple pi zeros from usb powered hub?

I do not see that as a problem. I have powered a mixture of Pi3 and P0W from the 60W one without issues. You do want to ensure you have good USB Cables to avoid getting continual low voltage warning appearing onscreen.

Not quite sure what you are asking? On the zero the micro usb power port has only the power lines connected (I.e. no data lines), while on the other port all lines are connected.

Re: Control Linux PC by connecting a Pi to it via USB

You do not mention what model of Pi?

For this to work you are going to need the Pi to be able to drive the USB port in ‘gadget’ mode. As far as I know only the pi0, Pi0W and Pi model A can do this.

From your description it seems unlikely that the Pi itself is faulty. The problem seems to be around trying to write new files to the SD card. Try running the command df and see if it shows there is spare space on the root file system. If the root file system is showing as full that would explain th...

What I find quite interesting in this thread is that nobody has mentioned that the amount of RAM that is allocated to the GPU (and thus not available to user programs) is variable and user configurable. Whether this is relevant to the question the OP was seeking an answer to is not at all clear.
