My arch install was crashing every single night, so I went back to old reliable Ubuntu 17.10 and followed Wendells guide. When it came time to apply the NPT patch I found that it’s already been included starting with 4.14.3.
Unfortunately, I just tested 4.14.4 which theoretically would have this patch, and it segfaults SDDM when it tries to enable the Nvidia proprietary drivers. STICK TO 4.13 IF YOU RUN NVIDIA DRIVERS.
