I am trying to install Ubuntu 13.04 (I also tried with 12.10) on an iOne gx31 with an E8400 processor. I run the DVD and it gets to the screen with the keyboard and little man then the screen flickers and I get nothing from there. If it's of any help I can put in a Macpup 5.2.8 or Vista and it will boot without screen issues. Any suggestions?

Boot into GRUB by pressing shift as the computer boots. In GRUB add acpi_backlight=vendor to the line that reads GRUB_CMDLINE_LINUX_DEFAULT=.

This should enable your vendor specific backlight. Once booted you can edit /etc/default/grub. After making the changes be sure to run update-grub to make the changes available to grub.
