First, upgrade to Raspberry Pi Os Buster.
raspi-config configures RealVNC VNC server. If you enable it, raspi-config issues these commands under the covers:
apt-get install realvnc-vnc-server
systemctl enable vncserver-x11-serviced.service
systemctl start vncserver-x11-serviced.service
A terminal is usually a monitor with a keyboard and mouse attached to a computer device. I assume you do not mean that, but a computer device like a PC, Laptop or smartphone. You also write that you use a network bridge on the RasPi. This isn't possible with a WiFi client connection to the router because lack of hardware support of the on-board WiFi chip. ...
You have to enter your router settings and search for your device MAC. Then set that as a static IP. Then also make a static port and then configure your router. Then you can register the IP in the router and enter rpi from that terminal. The thing is you have to know what to do with your router. I am sorry for not giving you any details since I use a ...
Interesting, as I'm trying to do the same thing.
I was aware of folks running Pi from a single FePO4 as these are between 3.2 and 3.3V normally anyway, and charging the cell in use by using a boost regulator running from a single crystal solar cell 0.7V 1A
One interesting modification, regenerate the 5V supply by using an isolated gate supply running off the ...
A quick search using the error message in your question was not particularly helpful, but a couple of things come to mind:
/tmp is corrupt/mangled
your SD card has failed & needs replacement
Here are some things to try. If none of them resolve the issue, I would suggest you try replacing your SD card.
1. sudo reboot
I guess you will have tried this by ...
systemctl status lightdm
It's probably running (lightdm is the GUI login, 'dm' = display manager). Change that:
sudo systemctl disable lightdm
sudo systemctl mask lightdm
Running both of them may be redundant but it won't hurt (see man systemctl for the difference).
You can then check systemctl status lightdm; it will still be running but the fact ...
