I quickly tested this in tumbleweed, leap 42.3, and centos 7 and appears to
help :)
Wow, Thanks!

I don't get the emacs logo - just plain text welcome, but at least I can
see minibuffer and type.

*However*, in Centos7 (with vcxsrv), the file menus don't appear OK when
clicked as previously reported (see gtk errors in previous posts)
A different issue?

Thanks!
