I just built a computer with two sapphire HD7950 graphics cards. I've tried installing both lubuntu and xubuntu (for scrypt mining) and in both cases the same thing happens. After the initial splash screen that just shows the logo and a loading thing, it goes to a black screen with a cursor.

If I CTRL+ALT F4 for example, it brings me to a xubuntu@xubuntu terminal window. I wouldn't mind that much only having a terminal, but I'd like to know how to get the GUI back.

Thanks!

EDIT: I have also tried with lubuntu the "nomodeset", which just displays a whole bunch of errors, most of them say SQUASHFS error: Unable to read data cache entry

Other distros had at same time this same problem, despite of installation-CD or DVD ... apparently it was forgotten to include the package of xserver-xorg in the installation-process.

If protected-mode is possible, you could try to install xserver-xorg by running the following command:

sudo apt-get install xserver-xorg*

After this, run the following commands in protected mode (Strg + Alt + F1) and install the graphics-drivers suiting to your graphics card.

sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev
sudo aticonfig --lsa
sudo aticonfig --adapter=all --initial
sudo reboot

After reboot is finished, run the following command in protected mode too with (Strg + Alt + F1):

sudo aticonfig --adapter=all --odgt

Now it should work...

I tried what dschinn1001 said but that didn't work for me. What did work for me was going into nomodeset mode.

In Xubuntu this is done at the options menu, select "Try Xubuntu Without Installing" press Tab and add nomodeset to the very end of the line. Press Enter and it will load right up. Then you can start the install from there.

In Ubuntu at the GRUB menu you press e to edit the line. Look for the linux entry and add nomodeset to the end of that line. Then press F10 to boot.
