I am attempting to install Ubuntu 13.04 on a 17" macbook pro and running into some issues that I believe are related to the video card (Radeon HD 6700M).
The steps took are: I download the 13.04 AMD64+MAC iso and make a bootable usb drive. I then boot off of the usb stick, select "Try Ubuntu without installing" and the screen then goes black and never recovers.
If I edit the boot parameters and add the nomodeset parameter Ubuntu boots to command line. Running startx at that point errors out saying that there are no screens available.
If I edit the boot parameters and add the radeon.modeset=0 parameter Ubuntu boots to command line again, but will then launch a GUI telling me that it is in low graphics mode. No matter which option I select from this dialog the dialog with vanish and I will be left at the command prompt.
I have also tried using the server install disk, with the same results (This actually confused me as I expected a CLI install).
Does anyone have any suggestions for how I can get Ubuntu installed on my Mac? As much as I would like a full UI I would setting for just being able to install a command line version.
