linux mint problems

[jemsurfer]

I followed a guide on setting up a virtual display #16 (comment)
but it didn't work, and the ui still crashes. Also, the virtual display doesn't show up when I do lspci | grep -E 'VGA|Display|3D'. I'm using linux mint ulyassa, the most recent version. It's an ubuntu based distro, so I thought it would work, but evidently not. I have an XFX amd external gpu, with amdgpu drivers
