Just installed Ubuntu 12.04 on my UEFI ASUS laptop. Upon my first boot I am presented with a terminal instead of the GUI. I get a no screens found error if attempting to use startx. I am using an AMD Radeon HD 7730M with a Radeon HD 7660G switchable graphics configuration. How do I fix no screens error?
I have followed the instructions on this page How to turn off ATI Radeon HD 7730M (on Dell inspiron 7520)? in order to load the driver for my GPU and have the same result.
After completing installation I attempt to verify using the following command:
fglrxinfo
I get Error: unable to open display (null).

Welcome to Ask Ubuntu! What have you tried? Using the search I find a lot of relevant questions. For example, does the following help you? Why my live installation results blank screen? (also Asus/UEFI) – gertvdijk Feb 05 '13 at 21:46

Open a terminal and issue the command:
sudo lspci|grep VGA
write down the first entries address xx:xx.x on the left (where xx:xx.x is the numbers displayed)
then issue the commands
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak (to back up your current config)
sudo nvidia-xconfig
sudo gedit /det/X11/xorg.conf (to edit configuration)
Move down to the Device section.
Just before the end section add BusID "PCI:XX:XX.X" Where XX:XX.X is your cards address you wrote down earlier.
Save the file, exit and reboot
