How to troubleshoot LightDM?

asked 2017-07-14 06:19:05 -0500

I wanted to try Fedora 26 or rawhide in virtual machine for some testing. However, it always hangs on black screen instead of going to LightDM.

I have tried it in VirtualBox and virt-manager with the same result. I have also tried Fedora 25 and 24. I am certain it worked before (like a few months ago), but it does not now. I have also tried GDM and KDM, both work fine.

I am running Fedora 25 as a host OS.

How would I debug/troubleshoot this situation, and narrow it to failing component, so I can report a bug?

Are you able to switch to another TTY and log in there? (Ctrl+Alt+F(x))?
