VNC on Buster-lite

Folks,

Curious, I run a few headless Pi projects so invariably use the lite version of Raspian.

I nearly accidentally enabled VNC on the lite version recently and it stated 168MB of space would be needed.

Without a desktop is this of any use?

Re: Old SD (or microSD) cards

I use old cards like that to build up systems for testing stuff out on. I can install a fresh Raspbian on them, try stuff out, then re-write them as required when it goes wrong. That is a decent idea,, I do have one of those plastic holder that store 8 microSD cards, don't write on the labels, just...

Use them for archiving data like pictures. They should be able to hold the data at least 20 years.
You'd have to be very methodical with records and storage.

Re: Old SD (or microSD) cards

In my experience, micro sd cards that aren't in use in a camera, phone or Raspberry Pi simply evaporate. Maybe they elope to Africa with ballpoint pens and teaspoons. My stash of full sized SD cards only reappeared in the desk drawer when I disposed of the last Pi that could use them. I've still go...

Old SD (or microSD) cards

Anyone any suggestions as to what to do with working but unused microSD cards. I recall when USB memory sticks first came out capacity was measured in MegaBytes, now we are close to Terrabytes being the norm. I've got a few 8GB class 4 cards that I am reluctant to just throw away, so small in size c...

It is Debian Buster 32bit Userland with an appropriate Kernel to match the CPU Architecture:

Code: Select all

/etc/os-release

The desktop environment is "Raspberry Pi Desktop" which is a fork of LXDE.

It doesn't matter whether it is clear to me. It apparently wasn't clear to you. How should it be modified to remove that uncertainty?

Is It Debian

Folks,

Started using Raspberry Pi Desktop for PC on my laptop, mulit boot with Ubuntu and Windows10.

Just checking, is the PC version actually Debian with an R-Pi designed Desktop. I am aware it is not the same version as used on ARM Pi SBCs.

Re: Back Voltage from USB Hub

I'm a wee bit puzzled with this back power issue. In the early days of Desktops, powered hubs were the norm otherwise, if used in passive mode the 4 (or 8) port hub could only use a maximum of 500mA being the current output of the single port the hub is plugged in to. I never had even heard of the t...

Re: Back Voltage from USB Hub

On a positive note, you could use one of the hub's USB ports and power a pi with that. As long as the powered hub gets more than 2,5A at 5V (1A at 12V) on the input, you can save cables there. (Meaning using data connection + power connection to the hub, for a more stable power). The problems usual...

You don't mention which model of Pi you have so it is hard to tell if you should have been surprised or not.
Only two USB ports so a very early one.

Would it be possible to open the hub and cut the 5v trace to the input socket?
I'll use it just as a passive hub.
