I get the GPU HANG as soon as I log into my computer and the desktop loads (or
tries to). 

Steps to repeat this:
I have a fresh install of arch linux and my machine boots into the terminal.
1) I log in
2) I start lightdm (systemctl start lightdm, i also have cinnamon installed)
3) The login screen appears - it is very sluggish, when i type the username it
takes a few seconds to show on the screen
4) I type in my username and password and press enter

The desktop is visible for a few seconds (the edges of it are not to the
monitors edge, and if i click on the menu nothing happens - attached 1.jpg),
then most of the screen turns black (the top left and part of bottom right is
visible, plus the mouse pointer in the middle - attached 2.jpg) 

If i put:  Option "DRI" "false" into the 20-intel.conf the login screen is not
as sluggish and desktop loads without a problem (of course with a warning that
it is running in software rendering mode). I opened a few windows and they
opened without a problem - I didn't test for very long though.

My configuration is:

Asus B150M-k
Intel G4400
Crucial DDR4 8GB 

Linux localhost 4.15.3-2-ARCH #1 SMP PREEMPT Thu Feb 15 00:13:49 UTC 2018
x86_64 GNU/Linux

The same thing happens if I boot other distros from Live USBs (tried Antergos
and Mint). I don't have this problem while running Windows 8.1.
