We have installed Ubuntu 12.04 LTS on an ASUS F83SE.

During installation we pressed F6 to use nomodeset and also set acpi to off.

Now that Ubuntu 12.04 has installed, the screen goes blank.

How can we overcome this problem?

The system's specifications:

  • Intel(R)Core 2 duo CPU T6600 @2.2O GHz
  • ATI Mobility Radeon HD 4570
  • 4GB RAM
  • Welcome to Ask Ubuntu! I just wanted to let you know that I have edited your question title to be more descriptive of the issue. Thanks!

You can revert to the terminal with ctrl alt F1 (go back with ctrl alt f7) and check the logs with dmesg and cat /var/log/syslog to check what is going wrong.
