Hi.
I do not know if I am currently being affected by the same Bug. My system is:
intel i7 3770 (HD4000 igpu)
nvidia GTX 960
I have Kubuntu 18.04 updated to date. I was using 390.48 nvidia proprietary driver correctly. I decided to try nvidia-prime in Kubuntu 18.04, so from the BIOS I enabled iGPU as the primary display. I opened nvidia-settings GUI and from Prime options I chose Intel. After entering user password, it took about a minute for the message to appear that the change had been successful. So I rebooted the system and it worked correctly, the system was using intel iGPU. But then when trying to return to nvidia something went wrong. After rebooting the system, PRIME options of nvidia-settings GUI disappeared. nvidia-settings GUI is only shown in the minimal version, only items from Application Profiles and nvidia-settings Configuration is displayed.
If I select my nvidia as a Primary Display from BIOS, the system enters in graphic mode but it apparently is not using nvidia driver, system and graphics work very slow and take time to refresh. nvidia-settings GUI just keeps showing minimal interface with almost no options. All this despite the fact that from the terminal, PRIME is informed that nvidia is selected:
$ sudo prime-select query
nvidia
I have tried to purge all nvidia package and reinstalling the driver from driver manager, but everything remains the same. Since troubleshooting nvidia problems is more difficult with new packaging system:

I do not know if I did it right. These are the packages that I currently have installed:

Just a question to see if I can reverse PRIME changes. Which configuration file is modified when you select nvidia or intel from PRIME options in nvidia-setings GUI (after entering user key)?
