Bug#1070284: Further explanation

I was full-upgradeing my debian testing machine and everything went
smoothly. Then, everything crashed: KDE Plasma, my IRC Client, but most
importantly: my terminal emulator, Konsole.

After rebooting Konsole, there was no way of seeing the progress of the apt
upgrade process, but it was still using 40% of my CPU so I figured it was
updating. I got help over on OFTC and we figured out that the apt process
had stopped because It was displaying an NVIDIA warning I couldn't accept
since the terminal emulator wasn't open.

Running sudo dpkg --configure -a restarted the upgrade normally, and know
when I do apt update it says everything is up to date, so I think nothing
worse has happened.
