Rebooting now takes me to a CLI login prompt. But when I try to give it my
login credentials, the screen flickers and then it takes me to the GUI
login prompt.

After logging in, everything seems to function as it has been since
installing last month, only it pops up a "system error" box, asks to load a
blue million files to file a bug report with, but after an hour it has not
done anything at all. (Literally an hour, I decided to wait since most of
the bug reports it has been filing usually take 3-5 minutes.)

Rebooting brings it back to the normal startup - that is, no login at all,
but straight to the desktop, like I had initially set it to do.

Rebooting again goes back through the login prompts.

When it goes through the login screen reboot (as opposed to going straight
to the desktop like it also does sometimes,) it is also completely ignoring
the 'viewportout' settings in xorg.conf.

The Xorg log shows a lot of nvidia and nouveau entries; but does not show
why that would randomly switch how it decides how to let me login.

udev log is ~14000 lines long, mostly relating to the sound. This makes
sense given the sound issues. but again - nothing pointing to login or
viewportout.

kern.log is also huge (~10000 lines), but the most recent entries are
primarily hda-codec related.

dpkg log is ~225000 lines long, and I honestly don't feel like spending my
day reading through that much stuff - I'm really not even sure what to look
for to find something relating to when it decides to take me to a cli
login, and gui login, or just go straight to the desktop - this was always
done as a 'set it and forget it' switch in previous versions of Ubuntu. why
they had to change it is beyond me.

gpu-manager.log, interestingly, ends with:

System configuration has changed
Removing xorg.conf. Path: /etc/X11/xorg.conf

Which is interesting since my system has *not* changed; all I did is
reboot.  And curiously, there IS an xorg.conf.

This latest solution does not seem like it is working very well at all.
