systemd-logind and seg faults when starting X

Installed Arch on my XPS15 9560 back in February, everything went smoothly, installed i3, and startx worked like a charm. For various reasons, I downloaded a newer Arch image last week, wiped my drive and reinstalled Arch. Same procedure, down to a tee. However, now I can't get startx to work.

I've run 'pacman -Syu', and installed i3, and the binary nvidia drivers, and xorg-server + other xorg packages.

Copied xinitrc to home directory and replaced the bottom crud with 'exec i3'. Running starts results in a black screen with no mouse; computer has to be shutdown using power button. There's no xorg.conf in /etc/X11.

The log from startx is below:

I've tried three fresh installs. Uninstalled/reinstalled, but I can't get this to start. I've tried adding 'blacklist nouveau' to /etc/mod probe.d/blacklist.conf' - no luck. 'modprobe nvidia' reports no errors.

I need some fresh ideas! Anyone have an insight into what's going on?

Re: systemd-logind and seg faults when starting X

Two things: set a hostname, not having one breaks things. And X -configure does the same.

Also, paste your .xinitrc

Re: systemd-logind and seg faults when starting X

@loqs As of my fully working Arch install three days ago (fully updated), using Optimus results in a kernel panic and renders the system unbootable which is described in the Arch wiki page for the 9560. They recommend a patched kernel if you want to use Optimis (which I have not done) but I used this exact machine for 6 months without troubles without optimis. All my attempts to previously get Optimus/bbswitch to work failed on an updated system three days ago failed, I'm hesitant to try it now? I'll look into it regardless.

@jasonwryan set a hostname. Still not change in any of the errors.

My xinitrc

#!/bin/sh

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then
    xrdb -merge $sysresources
fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f "$userresources" ]; then
    xrdb -merge "$userresources"
fi

if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi

if [ -d /etc/X11/xinit/xinitrc.d ] ; then
 for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi

exec i3

I tried nvidia-xconfig to generate a xorg.conf file. This is the result:

'X -configure' still seg faults, but startx now reports "No Screens Found" and then stays at the tty (doesn't go to the black screen)

Re: systemd-logind and seg faults when starting X

nvidia-xconfig does not produce a config compatible with hybrid hraphics.

[   835.039] (II) LoadModule: "glx"
[   835.039] (II) Loading /usr/lib/nvidia/xorg/libglx.so
[   835.088] (II) Module glx: vendor="NVIDIA Corporation"

If you do not want to use optimus remove the nvidia packages so X stops trying to use libglx.so as provided by nvidia instead of mesa which is incompatible with the integrated GPU that is attached to the display.
Edit:
You should also remove the /etc/X11/xorg.conf nvidia-xconfig created unless you want to use solely the nvidia GPU and can route the display output directly to that GPU in firmware.

Re: systemd-logind and seg faults when starting X

Removed all nvidia packages, deleted all xorg.conf, and rebooted. Startx still seg faults with the same backtrace.

I tried nouveau just to be sure, installed xf86-video-nouveau, modprobe nouveau (no errors), and then startx. No longer seg faults. Just repeats "Waiting for X server to start accepting display connections..."

Thanks for that note about nvidia and optimus. I was pretty sure that I was running the nvidia binaries on my previous install but I was clearly mistaken. Thanks for your help.

If I modprobe nouveau, lspci hangs and can't be killed with Ctrl+C. Requires hard shutdown.

Re: systemd-logind and seg faults when starting X

Is nouveau still blacklisted?  What is the xorg.log now?
