Same here, wx520. I discovered the following:
If I run "startx", and then "optirun glxspheres", and then I quit x and run "systemctl start gdm", gdm starts without crashing and seems to be ok. So the graphics card seems to be improperly inialized somehow when starting it from gdm.
This is with "pacman -S intel-dri xf86-video-intel bumblebee nvidia". I also tried uninstalling bumblebee, but gdm crashes then too.
It's exactly what happens to me as well. I dont have to do the optirun part tho. If I launch startx after I quit it gdm works smoothly otherwise it just freezes everything (I cannot even switch between terminals).

Same here; T420, but breaks bumblebee
The SNA fix https://wiki.archlinux.org/index.php/In … ion_method works for me as well.
I'm using a Lenvovo X1.
