Q:

Use Linux without a GPU

Is it possible do have basic (even just console) graphics on Linux, but without using the GPU (which, in this case, is fried and not replaceable)? Or would such a computer be limited to non-graphical uses only?
EDIT: The computer I'm talking about is an iMac with a broken graphics card/GPU, but everything else working (like the screen)

A:

Yes it is possible.
The software you need is vnc (server and client).
After the software is installed, you can remotely connect to a virtual desktop.
Also you can use Xvfb.
