I tried to install Ubuntu 14.04 LTS as a dual boot on my Alienware 15 R3 by following this document (https://github.com/awesomebytes/alienware15r3_ubuntu14).
However, when I boot Ubuntu from live USB (which means "try Ubuntu without Installing"), Ubuntu gets low graphics mode and cannot go further.
I think this might be related to graphic card (GTX1070), but I am not sure how to fix it.
When I tried Ubuntu 16.04 instead, it successfully worked but I need 14.04LTS...
Do you have any idea?
My Alienware 15 R3 is
CPU: Intel R Core i7-7820HK
GPU: GTX1070 8GB
Memory: 16GB DDR4 2400MHz (2x8GB)
Hard disk: 256GB SSD+ 1TB HDD
Thanks in advance
Dell never tested Linux Ubuntu on this Alienware 15-R3. We only tested/validated Windows 10 64-bit. You should post on the Ubuntu forum.
