Whenever I try to boot the system I get stuck at the Xfce logo screen and all I can do is access the console by pressing ctrl+alt+F1. It should however be supported by the preinstalled radeon open source driver. I have a Radeon r7 250 and according to the sticky it's neither supported by the proprietary drivers nor the open source amdgpu one anymore. I've been doing a lot of reading but I can't seem to get anywhere. Problem is I can't seem to get my graphics card to work. I'm trying to get a dual boot system running with Windows 10 and Mint 19 Xfce (64 bit). I'm completely new to Linux and kind of lost at this point.
