Hi. I'm new to Ubuntu and I cannot speak English very well.

I installed ubuntu 12.04 lts and it worked very well. but now it cannot start. I only see the logo an then just this text:

fsck de util-linux 2.20.1
/dev/sda7: clean, 217248/1490944 files, 1307260/5959424 blocks
skipping profile in /etc/apparmor.d/disable: usr.bin.firefox
skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd
*Starting AppArmor profiles             [ok]
speech-dispatcher disabled; edit /etc/default/speech-dispatcher
saned disabled; edit /etc/default/saned

Please, does anyone have any idea what happened or know what I can do? Many thanks from Argentina.

  • I see notices, no errors.

It does look like a video driver issue that is causing plymouth and lightdm to fail to start. However, I think you'll find the machine has booted and is operational, albeit in text-only mode

You can go to a tty (terminal/commandline) by pressing CTRL+ALT+F1. You should see a prompt asking for your login an password. Login and try to re-install your graphics drivers.

If you're using NVidia, it's most likely

sudo apt-get purge nvidia-current


sudo apt-get install nvidia-current

After that, run sudo reboot.
