All kinds of Ubuntu troubles (fixed)

All three kinds of Ubuntu troubles (all of them fixed)

1. Can't get Ubuntu to start up without using recovery mode? Try making this change in /etc/defaults/grub


But then don't forget to

$ sudo update-grub

I've lost track of all the sites I looked at that steered me in the right direction, but I was still having trouble because I'd forgotten the update-grub step!

2a. Trouble getting VNC to install and start up? Look no further than Ubuntu's own Screen Sharing feature!

2b. Once I got that working, I discovered that I could not connect using:
  • the RealVNC viewer (error: "Unable to connect to VNC Server using your chosen security setting. Either upgrade VNC Server to a more recent version from RealVNC, or select a weaker level of encryption.")
  • MacOS Screen Sharing (error: "The software on the remote computer appears to be incompatible with this version of Screen Sharing.")
Fortunately I found a video explaining the solution. Install and launch dconf Editor. Then navigate to org > gnome > desktop > remote-access and turn off the require-encryption option. Once I did this, I was able to use all of my VNC clients!
