Linux Clear Kernel: Optimus Manager doesn't work properly

For several months I'm using Linux Clear kernel built from AUR. I like its balance between performance and UI responsiveness and found that the system works more stable than arch/zen/ck kernels.
But found an issue: Optimus Manager can't switch between Intel and nVidia graphics.
When I attempting to switch, it just restarts X session under Intel graphic processor.
Any other kernels do not face such problems.
My video card: nVidia GM108M / GeForce 840M
Processor: Core i5-4210U
I use only X11.

Re: Linux Clear Kernel: Optimus Manager doesn't work properly

Aur lists 2 optimus-manager packages building stable and 2 building git versions .
Which of the 4 are you using ?


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: Linux Clear Kernel: Optimus Manager doesn't work properly

The nouveau kernel module is included in archlinux kernels.

Try blacklisting nouveau .

Blacklisted nouveau and removed nouveau from the kernel. The message is disappeared, but the problem still exists.
I suppose that an issue is on kernel site.
