Black Screen stuck launch on Linux

Hi Folks,

Here is the scoop:
I'm on Linux Mint 18.1
uname -rv
4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6 17:47:47 UTC 2017

I mistakenly installed the older 5.0 release from the forum thread and, as expected, got the "Service not available" error.

I then uninstalled, and installed unity-editor-amd64-6.6.0xb3Linux.deb

The install works fine, then when I run I get this:
1) The blue Unity spash screen pops up
2) A black "gettingStarted" window pops up and hangs with nothing in the window.
3) When I close that window, a small dialog titled "Hold On" pops up creating directories in my user directory then Unity exits.
4) Now when I start the Unity spash pops up, then an empty black "recent" window pops up and hangs.

I suspect I just have some files hanging around from the first install. I have tried to uninstall, then delete everything I can find related to Unity (from .cache, .config, ProjectSettings, Library, Assets), but the best I can do is get it back to the "gettingStarted" hang. Apparently something is still sticking around that I don't know about, or something else is wrong.

I think I just need help knowing where to look for every possible thing I need to delete (assuming that is in fact the problem).

Thanks in advance for the help

Many people is having the same problem as you, and there is a solution for it(worked many times).

 

Thank you diegomendes! That worked for me.
