This bug also affects me.
I am running Kubuntu 18.04 on Gigabyte AERO14, CPU:i7-7700HQ (45W TDP), GPU:Nvidia 1050Ti
I took a full system image with clonezilla, and tested Alberto Milone's PPA. System working fine after the upgrade. I tested switch+reboot around 20 times.
Test results:
No issue rebooting with or without switching GPU.
GPU Switching: Switching GPU is now much faster. Even if i use it from nvidia gui, I get the popup window asking to reboot right away.
system shutdown/reboot after I switch gpu is fast. Usual 5~10 seconds, same time it takes when I am not switching gpu.
Power usage - Nvidia mode: powertop reports around 30w idle (cpu load:2~3%, gpu ops/sec:0)
Power usage - Intel mode: powertop reports around 20w idle (cpu load:2~3%, gpu ops/sec:0) - Device stats report usage of 100% of the Nvidia 1050 in powertop, not sure if accurate.
