Generally speaking there isn't a reason for the inspiron not to accept Linux. Linux is pretty versatile over hardware now...especially the Ubuntu distribution since Dell has partnered with to install on their laptops at the factory. If you have swapped hardware out or installed a brand new video card that the community or vendor has not written a driver for than it could be foreseeable that you would have problems. That would be across any OS though and not just Linux.

Answering your question is a little tough however, as you have not said what error you are seeing, whether you've attempted to install Linux, what particular distribution you've used.

Du you get any errors??
