I had been using Ubuntu 13.04 and I chose the upgrade option from the Ubuntu live CD and chose to keep the installed file as it is. The installation successfully completed with an error message saying some older packages may have to be reinstalled. I restarted the computer, but now I can't login to the computer in GUI mode. It gives an error message that it can't find graphics drivers. When I click on the only available button OK, I get the following dialogue box:

enter image description here

and then when I click the first option I get this one :

enter image description here
which never restarts anything.

Clicking the second option gives the following: enter image description here

and clicking OK gives the same dialogue box recursively.

Third option shows a error log file and fourth option lets me smoothly use the Ubuntu 14.04 in GUI mode and my files are safe in my drive.

So how do I get rid of this problem? I assume graphics drivers come with Ubuntu 14.04 itself.

  • What graphics card do you have? – Nattgew Apr 28 '14 at 18:14
  • AMD graphics card. I have intel 4200U i5 CPU. – pranphy Apr 30 '14 at 08:44
  • @PrakashGautam Which one exactly? Use lspci in the command line to get the exact spec. – mcantsin Apr 30 '14 at 08:49
  • 00:00.0 VGA compatible controller Haswell-ULU Interated graphics Controller (rev 09) 03:00.0 AMD nee ATI Sun [Radeon HD 8600M Series] – pranphy Apr 30 '14 at 10:47
  • Same happened to me, just remove graphic drivers, reinstall x.org, lightdm, ubuntu desktop and have fun – Emin Mastizada Apr 30 '14 at 12:53
  • how do I remove graphics drivers when all I get are the error messages mentioned above and can't penetrate into user interface of 14.04? – pranphy Apr 30 '14 at 12:54
  • so what's the error log file? – arsaKasra Apr 30 '14 at 15:50
  • From the CLI, run this command: dpkg -l | grep fglrx | awk '{ print $3 }'. This command will print out the version number of the fglrx (ATI) driver that you currently have installed (if any). Additionally, please provide the output of: modinfo fglrx | grep "^version" | awk '{print $2}', which will give use the version of fglrx currently install and being used in the kernel. I have a hunch that update-initramfs may have packaged the wrong version of the driver into the initramfs, leading to graphics problems. Or, perhaps, it's not even installed -- which may give the same results. – Chuck R May 01 '14 at 15:38
  • dpkg -l | grep fglrx | awk '{ print $3 }' gives nothing but modinfo fglrx | grep "^version" | awk '{print $2}' gives ERROR: Module fglrx not found. – pranphy May 05 '14 at 11:58
  • What does /var/log/Xorg.0.log say? Your system has both Intel HD4400 graphics and AMD HD8600M. Perhaps fglrx got removed, but xorg.conf is still configured to use it? Try deleting your old xorg.conf as the answer below suggests. – bain May 05 '14 at 22:06
  • @Prakash Gautam please provide your aforementioned error log file. Please help us help you. – Elder Geek May 07 '14 at 01:14
  • I tried to view the file with cat /var/log/Xorg.0.log which shows a long file and I am sorry I don't understand what the information mean! – pranphy May 07 '14 at 11:46
  • You don't help mentioning the size of a file content. But you may help uploading it into a web service where we can read it. Upload it here and link it in your question- – Lucio May 11 '14 at 18:25
  • I so very much want this question be be reconsidered. I am in a deep trouble as I keep on getting 404 Not found whenever I try to install new packages. I still have this problem. – pranphy Dec 15 '14 at 18:09

I have the same problem every-time when i try installing ATI graphic card drivers on my hp laptop.

I think your problem is your graphic card drivers supported in 13.04 version are not working in the 14.04 version. so you need to uninstall the graphic drivers.

To uninstall the graphic drivers, boot into recovery mode run as root and try uninstalling your graphic drivers if you installed fglrx then you can try this command

sudo apt-get purge fglrx

and reboot

I hope that works

    Hmm, this seems almost correct except that at the end of this the user is left without a graphics driver -- instead using Vesa which probably won't work out too well. We may need some more information about this in order to properly rectify the problem. – Chuck R May 01 '14 at 15:32

Boot into recovery and remove your xorg.conf file, then reboot.

sudo rm /etc/X11/xorg.conf

log into a teminal:

Hold CTRL and ALT and tap F1

login

issue the command

sudo X -configure

Tested on Ubuntu 14.04 by yours truly. I can verify that the command is recognized and accepted. YMMV (I get display already active which in my case is true)

  • Sorry I may be doing some silly error here; when I do CTRL+ALT+F1 I get a console screen; but I can't login. It says incorrect login. I enter and but it says incorrect login. Now I have installed 13.04 back. I may be able to do that from terminal, to prepare for 14.04 installation. Is that possible? – pranphy May 05 '14 at 12:02
  • @PrakashGautam I would prepare for installation by backing up all my data. Once I was sure I had backed up everything I needed I'd wipe the drive and install fresh. Then copy my backed up data onto the system. Since you've installed 13.04 back this question is no longer relevant to your current situation. It's still a valuable question though. We appreciate you bringing it to our attention as it is likely to help others. I experienced too many problems with both 13.04 and 13.10 to consider using them seriously. 14.04 is so far much more stable for me although I still run 12.04 for benchmarks – Elder Geek May 05 '14 at 13:41

Press Ctrl + Alt + F1 and login.

If you've installed fglrx using apt-get/Software and updates:

sudo su
apt-get purge fglrx*
reboot

If you've installed fglrx from AMD's website:

sudo su
cd /usr/share/ati
bash amd-uninstall.sh
reboot

After rebooting, press Ctrl + Alt + F1, login again, and then install open-source drivers:

sudo su
apt-add-repository ppa:oibaf/graphics-drivers # Optional, gives little performance boost
apt-get update
apt-get install --reinstall xserver-xorg-video-intel xserver-xorg-video-ati xserver-xorg-video-radeon libgl1-mesa-dri libgl1-mesa-glx mesa-vdpau-drivers
dpkg-reconfigure xserver-xorg
reboot

And never install fglrx again.
