I'm physically in the living room, Mac Air on my lap, connected by VNC to the Raspberry Pi in the basement.
Getting this far has been a struggle, as my former password, AFAIK, had stopped working. Had I forgotten resetting it? But then why did passwd reset seem to work, yet not work. Something about /etc/shadow?
Anyway, I followed instructions to change cmdline.txt on the Micro SD card, an hour-long project given my best card reader adaptor was not the one that ended up working. Then came other issues, requiring a remount and so on.
Now, at last, I'm able to do what I used to do: use VNC from a remote laptop to get the Raspberry Pi desktop. Yay.
In celebration, I opened Blogger from the Pi and am writing this blog post virtually, from 192.168.1.5 behind the router, not from the Mac Air.
