Upon upgrading to GNOME 3.20 (among approximately 170 other software updates), my Antergos machine reboots about five minutes after logging in. It doesn’t seem to matter what I’m doing at the time the machine crashes. Upon crashing, the display just goes black and presents the same on-screen text it does at boot and hangs there for an indefinite timeframe (starting version 229 /dev/sdc2: recovering journal…). I’ve tried disabling all GNOME shell extensions in the GNOME tweak tool, disabling all non-default GNOME themes, and booting from the linux-lts kernel.
My system details:
CPU: AMD A10-5800K APU
GPU: GeForce GTX 660
RAM: 16 GB
Kernel: x86_64 Linux 4.4.5-1-ARCH
NVIDIA Driver version: 361.28
I run gdm instead of lightdm (in case that makes a difference)
