This would be best researched in the Linux Mint community -- someone may have tried it or be better able to answer questions about what does and doesn't work.  
I am thinking about getting this laptop for my AI studies, but it is a necessary condition that it will run Linux, preferably Linux Mint. So I am aware that Dell does not support the OS but I would like to know if anybody has experience with installing Mint on that system or if there are any known issues? Probably I would do a dual boot installation with keeping Windows, but that is not necessary.
