Bug#865759: Kernel 4.11 seems to fix it

[TarotApprentice]

On a clean-installed Stretch (Intel core i3 using built-in graphics) machine which was only displaying the Debian wallpaper after login I then installed kernel 4.11 which seems to fix the issue. I had to ssh into the machine and install Linux-image-amd64 from Stretch-backports. After install reboot. Desktop now displays icons, menu bar and task bar.

Kernel installed by Stretch netinst 9.1 would appear to be 4.9.30. Kernel from Stretch-backports appears to be 4.11.5
