Gnome only working with mesa-libgl, not with nvidia-libgl

This is driving me nuts. Gnome does not start with nvidia-libgl, only with mesa-libgl.

I have an nVidia GTX980 on intel Skylake architecture (Core i7-6600K).

intel-ucode is installed, the intel-ucode.img loads before the initramfs via systemd-boot

#  /boot/loader/entries/Arch.conf
title     Arch Linux
linux    /vmlinuz-linux
initrd   /intel-ucode.img
initrd   /initramfs-linux.img
options root=PARTUUID=<numbersandlettersanddashes> rw

After

pacman -S mesa-libgl
systemctl reboot
systemctl start gdm

everything is fine, i. e. the greeter shows up, I can login, gnome-shell comes up, I can work with gnome. Currently starting gdm manually because of the issues with nvidia-libgl.

However,

glxinfo | grep renderer

lspci -knn | grep -i vga -A3

If I now switch to nvidia-libgl and reboot, gdm would error out with "Oh no! Something has gone wrong."

pacman -S nvidia-libgl
systemctl reboot
systemctl start gdm

If I start SDDM instead of GDM, SDDM will launch the greeter and let me enter my password. However, after that, gnome-shell comes up showing "Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again." If I hit the "Log Out" button, I am back in the greeter. Groundhog day.

What can I do to have my laptop use the nvidia-libgl?

Thank you.

Ah, news: it seems that sometimes Gnome also does not start with mesa-libgl. This is if USB devices are plugged in (headset, keyboard, mouse). I will investigate later which of them it is.
Edit: this seems to be so sporadic that I could not reproduce it so far.

I wasn't able to get GDM/Gnome running with nvidia for a while (months), but then I was told to install intel-ucode to fix a seemingly unrelated error, and ever since then gnome+nvidia has worked perfectly for me on a MacBook Pro (Retina, 15-inch, Mid 2014).

Hey joejoejoe,

thanks alot. I read about that also, probably in the same post, and implemented that before my post.
