If you look on your laptop's Dell Support page, you'll see that it supports Ubuntu.  Even if Dell doesn't officially support Linux on a particular computer, you can likely install it and drivers will  be found. I've installed Ubuntu, Xubuntu and Mint on a few old Dells that officially don't support Linux.
Does my laptop (Dell G15 5520) has Linux support? Can Linux be installed in this laptop baremetal?
