Bug#900248: update to 390.59 breaks direct rendering

[Dean Loros]

Yes--I've got the "black screen" upon update to 4.16-2 also. Have
reverted to 4.16-1 until this latest "fupa" is found....Very willing
to test options if you have them...am back on the "first fix"--the
config went out the door with the kernel update--only the creating an
alias works right now. A side note: took 4 minutes of grinding to get
to desktop...mutiple GDM errors before it "took".  Error:
pam_systemd(gdm-launch-environment:session): Failed to create session:
Start job for unit user at 116.service failed with
'dependency'-----pam_systemd(gdm-launch-environment:session): Failed
