After the update today no graphical interface anymore - 12.04 [closed]

Question

I installed the updates through the update manager today. I shut down my Laptop and now after starting it up again, I only get terminal access to advices.

Grub is loading fine and after I picked Ubuntu 12.04 the screen get blank and I am asked to log in with my username and password in command line mode. If I log in I am still in command line mode.

How do I get the "normal (graphical)" Ubuntu back? I hope you know what I mean. Since English is not my first language I can't explain this the way I would like to.

Answer 1

I also faced the same problem. It's the process beyond battery check, I suspect it's choice of display manager - lightdm or gdm, 12.04 uses lightdm. I did a fresh install. I did not have 12.04 CD. So installed 11.10, then upgraded, then installed the package list from my other laptop to have my complete list of software back. Hope this helps.

Try pressing ctrl+alt+F7 to switch to a graphic mode. If that doesnt work try checking your fglrx display driver info by running a command in the terminal - flgrxinfo

If that states something like this -

display: :0.0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6500M/5600/5700 Series
OpenGL version string: 4.2.11631 Compatibility Profile Context

then your grphics driver is not missing

I hope you didn't do a clean install yet. In most cases there's an easy fix for everything!

with this particular problem please try resetting your graphic drivers to the 'out-of-the-box' state. Please enter the following commands,

IF YOU'VE INSTALLED THE DRIVERS FROM SOFTWARE CENTER OR 'ADDITIONAL DRIVERS' :

sudo apt-get remove --purge xorg-driver-fglrx fglrx*
sudo apt-get remove --purge fglrx*
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo dpkg-reconfigure xserver-xorg

IF YOU'VE INSTALLED FROM ATI HOMEPAGE :

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx*
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx libgl1-mesa-dri 
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo dpkg-reconfigure xserver-xorg

Reboot.
Ubuntu should now boot in graphical mode.
If you wish you can reinstall the ATI drivers again, or just use the open-source drivers
(whatever suits your needs)
