UPDATE: I have downgraded the kernel, and it solved the issue. Seems the kernel itself is buggy.
Today morning I performed system upgrade (07:44 AM IST). However, after restart (kernel was also updated from 4.4.3-1 to 4.4.5-1), lightdm fails to load. I am not even able to "startx" from shell (it just sits there waiting for X server to accept connections). However, lightdm starts if I disable and enable lightdm from root, and restart. Next reboot, and again it won't load.
Anyone suffering from this? How to fix it? Any help wil be appreciated.

I have become death, the destroyer of worlds.

Same problem here while updating to kernel 4.4.5, only solution was to downgrade.
I see you are also using radeon, maybe this comes from there.

No issues here
Running without issues these packages now
linux 4.4.5-1
lightdm 1:1.16.7-3
lightdm-gtk-greeter 1:2.0.1-2

Also stuck in login screen after upgrade the kernel to 4.4.5 with ati driver, but mine is SDDM rather than LightDM.
Downgrading the kernel just solved it.
Offline
I had the same issue, had to downgrade the kernel.
Since I'm quite new to Arch, I wonder what will happen with this bug in the future? When the next kernel version is available, will pacman -Syu upgrade the kernel, even though I have explicitly downgraded? And if the bug still is there, I have to downgrade again, I suppose.

So it is not a kernel issue but an ATI driver one. Again ?!

If you're worried it will not be updated by then you can use the option IgnorePkg=linux as described here

Does anyone know if this bug is reported, and if it will be fixed in some future release?

Is this the same problem as here? I posted a fix for the lightDM greeter failing to load there.
