** Description changed:

- I've installed ubuntu desktop 17.10 amd64 from scratch in UEFI mode on a Dell 
XPS 15 9560 laptop.
- This laptop comes with i915 built-in graphics, as well as an NVIDIA 1050 GPU, 
but I am not trying to make the NVIDIA work yet, and have blacklisted nouveau.
- I'm using xorg 1:7.7+19ubuntu3
- xserver-xorg-video-intel/artful,now 2:2.99.917+git20170309-0ubuntu1 amd64
- I have to set acpi_rev_override=5 in the kernel boot parameters, because
- rev 6 causes other bugs (hang on shutdown, for example.)
- I'm using whatever the default desktop (presumably Gnome) and compositor
- are for a ubuntu desktop install.
- I can boot to login; I can log in to desktop, but shortly after desktop 
login, the screen goes black, and after a little while, I'm back at the login 
- Logging in again, works, but at that point, I believe I'm in "dumb software 
+ Shortly after logging in for the first time, the screen goes black, and
+ after a little while, I'm back at the login screen. A subsequent login
+ puts me in "dumb software mode."
