This is exactly what happened to me! I used Mint Linux 18.2 and had major technical problems so was looking for a replacement. I found a distro that sounded appealing and just read it's "desktop LXDE". Thinking it's the OS name (I'm new to Linux) I googled it and it lead to me LXLE which I installed. I fell in love with it quick and it had no issues that I had with Mint Linux.
