Ubuntu 12.04 boots to TTY1

Question

Alrighty, I have perused the threads already in existence and am finding none of them seem to have the exact combination of variables I've got going.

I'm working on a computer using Ubuntu 12.04. Currently, it boots straight into tty1

Ubuntu 12.04.4 LTS [computer name] tty1

Welcome to Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-32generic-pae i686

The owner of the computer stated that this issue happened after a recent update, if that gives anyone a hint as to the specific location of the graphics failure.

I'm capable of booting into the GUI utilizing startx, but am frankly at a loss of where to go from here. Years of Windows has molded me into a GUI heavy kinda person, so, if possible, work off the assumption that I've no idea what you're talking about and break it down to the simplest of steps.

Thanks!

Solution 1

You could use this command to turn the Xserver back on.

sudo systemctl set-default graphical.target

Just for future problems.

Solution 2

or try to use this command:

startx

Solution 3

I did this:

sudo apt-get update  
sudo apt-get install --reinstall ubuntu-desktop  
startx

Solution 4

I have had the same problem, and you can install the ubuntu again by typing.

 Sudo apt-get update
 Sudo apt-get install --reinstall ubuntu-desktop
 startx

And it should work.

EDIT: line 2 should install ubuntu-desktop (with a dash), not ubuntu desktop.

Sadly, reinstalling Ubuntu hasn't remedied the issue. Also wiped and reinstalled my lightdm and didn't get anywhere with that. (Nor did an install of gdm help, sadly.) I can manually start lightdm from the terminal, thus opening the GUI, so that appears to be working at least. Truth be told, I can't wrap my mind around this--any clue where my problem is?

startx opens the default desktop environment, but that's only a temporary solution. Whenever I next boot, I'm right back at tty1.

In fact it would help if you posted the full grub file for us to examine
