I am still having flickering woes, and I'm increasingly convinced that simply installing xf86-video-intel and xf86-video-intel-32bit isn't sufficient to actually switch to the intel DDX, instead of modesetting. (See below.) Can anyone shed some light on how to switch from modesetting to intel? I have the feeling that the wiki's documentation may be out of date (or things aren't working as they should).

I got some flickering with "i915.enable_psr=0", so I've removed it and have installed xf86-video-intel and xf86-video-intel-32bit, which pulled in libvdpau_va_gl1, libvulkan_intel, libxcb-util1-32bit, libXv1-32bit, libXvMC1, and libXvMC1-32bit. I haven't seen any flickering since installing these, but it has been very long. Also...
Am I right that I can switch to the Intel DDX by just installing xf86-video-intel? That's how it has always worked for me. /etc/X11/xorg_pci_ids/modesetting_ids supposedly exists to be able to override it, but it has only ever been a 2 byte placeholder for me. If I'm reading the following from "inxi -Gxx" right, though, it doesn't look like I am using the Intel DDX after installing it.

Am I misreading this, or is there something more I need to do to use the Intel DDX?
