Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am starting a small side adventure with my Pac-Man ghost inspired Raspberry Pi project. Let’s get started!
This week, I took a break from programming. For weeks now, I’ve had to share an HDMI monitor between my desktop and my Pi, which I’ve named Blinkie. In past weeks, I’ve setup a VNC server so I can remote in and take control of Blinkie from my desktop with a VNC client, but I have a few edges to smooth out.
Firstly, the system seems to get its resolution from an attached HDMI display. If I boot it up headless (no monitor attached) then Raspian will boot the GUI into a low-resolution mode, presumably to save on CPU time. If I later connect a monitor later, it doesn’t auto-adjust, and I end up rebooting. I’ve taken to going behind my monitor and switch the HDMI inputs, and they can be difficult to get on the first try.
Secondly, when I’m no longer working on Blinky, I will have two jobs for it. Guard the kitchen, and stream the Church service on Saturday morning. This will imply both headless and headed operation. I can easily optimize for one or the other, but getting it just right will be tricky.
The bulk of my work this week went into turning Blinky from a more tiny Desktop into more of an actual security camera arrangement. I taught myself about SSH, the most fundamental skill I’ll need for operating it at a distance. SSH feels similar to VNC, but only for the command line in that it has a server and a client. Since I’m starting with optimizing for the security camera configuration, I found a way to boot to CLI, the command line only, and a way to enable a virtual desktop in memory from that command line. I ran into a little surprise.
The first problem I found was a quick fix. Instead of the traditional pointer I’m used to, it favored a black X. LINK to the forum thread I used. Another issue was the unexpected evolution of the aspect ratio. I ended up just moving the whole VNC window over to my other monitor, since it about fit and I don’t particularly relish the black boarder around the desktop. I can rework my workflow on Blinkie to accommodate the narrower work area.
I still have some bits to figure out. The mouse buttons are still double swapping. If I’m going to be going between headless and desktop modes, I want to have a consistent, swapped button experience. The worst case scenario right now is where I run a bash or other kind of script and program it to change the setting based on if there’s a monitor connected on startup.
I also need to find an easier SSH client for Windows or else find a way to zoom in on the text. Also against the default Windows SSH client is the fact I cannot just paste a long, super secure password into Command Prompt for logging in. In addition, I may be interested in looking into an Android SSH client for both now and future projects.

Final Question: Have you ever used SSH on an Android device before? Do you recommend any in particular?
