Hi, thanks for cooperation.
Answers: It happened after regular upgrade and reboot. All Xenial's kernels before latest were OK.
So it is probably regression.
I reinstalled Ubuntu (by using alternate Lubuntu iso, I use RAID and Ubuntu iso cannot deal with it.)
and everything was OK, until upgrade to latest kernel - everything (graphics) is distorted (systemd) or does not boot at all (upstart). Bug report: bug #1607006
And again, boot to kernel before latest is a workaround.
I will try upstream kernel and complete this report.
