Running X solely on dedicated GPU

About a year ago when I was using arch, I was able to configure x-server so that it ran directly on my dedicated nVidia GPU (I have a laptop with Intel integrated card and nVidia dedicated) using xrandr, after having followed their tutorial on the ArchWiki. Around in august, an update (of x-server I guess) caused x to give the typical no screens found error at startup, so I was forced to change the .xinitrc and the xorg-config back to default in order to run it. Now the same thing happens in the event of trying to run x on a dedicated GPU via xrandr. I need to know if there is anyone successfully doing it right now, or if there is a valid way (arch haven't updated their wiki article since).

*Bumblebee yields awful results for me FPS-wise, so much that using Intel for gaming is actually better than the dedicated card
*I am using KDE with compositing disabled
*Using a different DE doesn't positively affect my gaming experience
*I cannot disable the integrated GPU in bios. (only the dedicated can be disabled)

That being said, instead of alternatives to this, I'd like a way to use the optimus technology via xrandr.

Here's the tutorial I used back then: https://wiki.archlinux.org/index.php/NV … e_graphics

Are you running into this: https://bugs.archlinux.org/task/47151

It is affecting me as well.

Re: Running X solely on dedicated GPU

Downgrading xorg-server xorg-server-common back to 1.17 is the only way I can run my dedicated Nvidia GPU since the 1.18 update was released.
