I have little knowledge about ubuntu, but I am learning. Recently, my ubuntu 12.04 required that I update. I noticed that it was updating xorg and other things, after the update I was asked to reboot. I did. now when I start that computer up, it cannot detect any display and refuses to boot from usb. I have no idea how to recover my computer. It simply starts in what is akin to the terminal program and ask for my username and password. After that, I can enter commands.

The problem may be because I manually installed drivers by copy pasting from some instructional that I now have no idea where they are, but what it amounts to is that I "built" the drivers. They were working GREAT until this update. I did this because otherwise I was unable to have sound through my hdmi. After I hand built the drivers, they worked great. After this update Ka-blam! nothing...

Also, I had okay-ed lots of update sources (though all of them [xorg and such] were the stable versions, not the unstable update sources)

Please help and thank you in advance. (if this is posted incorrectly or misplace, please let me know what to do)

I think that:

  • your ATI drivers may have not been well installed
  • and that the free drivers have been removed.


So I suggest you to:

1 - uninstall ATI drivers doing this

$ sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*


2 - install the free drivers

$ sudo rm /etc/X11/xorg.conf
$ sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 xserver-xorg-core
$ sudo dpkg-reconfigure xserver-xorg


3 - reboot

$ sudo reboot


4 - check if your graphic card works correctly with the free drivers


5 - if your problem is solved after step 1 to 4, and you still want to install ATI drivers

Then to get the instructions to re-install your ATI drivers, if your card is a Radeon HD 3xxx or HD 4xxx: follow this answer starting directly at Download driver part.

  • okay, that is a huge improvement. I still don't have super success with the drivers, but I am back in!! Thank you so much. still have some untangling to do. I have 5xxx drivers, do you have some idea about that? Again. Thank you VERY much! – Michael Dec 15 '12 at 21:03
  • wait, it is doing it again and now the instructions don't work. It keeps wanting me to update... and every time i restart, this happens... – Michael Dec 15 '12 at 21:23
  • okay, got it going again. working through the ati install on the link you gave. got confused because my graphics say 4xxx/5xxx, but the hdmi sound is with the 4xxx and this is what I have a problem with. – Michael Dec 15 '12 at 22:04
  • have you done all steps till 5 (trying to install the ATI drivers) or have you stop to 4? if you tried till 5 I would suggest you to stop at 4. – Boris Dec 15 '12 at 22:47
  • to know if you can use the solution in my link (step 5) please edit your question and add the result of this command lspci -v | grep -A 12 VGA to know what is your graphic card – Boris Dec 15 '12 at 22:49
