I am having trouble starting my system. I am running Ubuntu 12.04 off a 16 Gb flash drive on a 64 bit HP Pavilion laptop. I have an intel chip and nVidia graphics with proprietary drivers installed. I am not able to get to the login screen at all, and the system is behaving oddly in general. What happens when I start the system is:

-BIOS prompt to press ESC for options

-purple screen (so far, so good)

-loading screen

Ubuntu 12.04

....

-after a couple seconds it becomes:

Ubuntu 12.04

....

Waiting for network configuration

-after a couple more seconds it becomes

Ubuntu 12.04

....

Waiting up to 60 more seconds for network configuration

-Then it becomes

Ubuntu 12.04

...._*Checking battery state [ OK ]

Booting system without full network configuration...

-The first 2 dots under Ubuntu 12.04 are orange, but the next 2 are white

-After approximately 20-30 seconds the screen cycles between black screen without cursor, screen totally off, black screen with cursor, and then:

Ubuntu 12.04

...._*Checking battery state [ OK ]

Booting system without full network configuration...

again. Then it continues to cycle through the black screens without the loading screen. I tried starting xorg through TTY1, as per a post I saw earlier but can no longer find. I used $startx but it got stuck at:

Loading extension GLX

I should note that when I am in TTY1-6, it seems that I am put right back into TTY7 automatically after a few seconds. I don't lose the output or what I type in TTY1-6 though.

It might help to know that I was having issues with Unity a couple days ago, and then I had issues with my laptop's touchpad, but I am pretty sure I resolved these problems.This particular problem I'm having now started after my laptop got unplugged without the battery in.

Does anyone have any idea what might be causing this or how to go about fixing it? Any help is appreciated. Thanks!

Sorry for all the edits. I'm on a tablet and can't see how the post looks until it's posted.

I also noticed that trying to shutdown through TTY1, using $sudo shutdown now doesn't work. The screen freezes at Ubuntu 12.04 ....root@joel-PC:~# –  user212062 Nov 27 '13 at 22:37

If your screen goes off while booting try adding nomodeset to your default grub option by pressing "E". You will see linux /boot and at the end you place nomodeset by splash. Give that a try!

Here is a thread about it more.

Thanks for the tip, but unfortunately I am still having the same problem. –  user212062 Nov 27 '13 at 22:35

I have decided to do a fresh installation of Ubuntu, as I have no important data on this computer. I think this is probably the fastest and easiest solution under the circumstances .
