How to switch to the modesetting driver from xf86-video-intel

Hi everyone, I'm struggling to find out how to use the modesetting driver. I've scoured over a lot of forums over this.

Is it enough to do this? Furthermore, will these setting even be used if I'm using gnome with wayland? I'm asking since this is an xorg configuration file.

/etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "modesetting"
EndSection

What are my options? Any help is appreciated!

Just remove the xf86-video-intel package, no other configuration is needed.


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

No need for any config file, X will fall back on the modesetting driver (provided by xorg-server package) if it doesn't find xf86-video-intel .

I think wayland uses the mesa drivers directlyto drive your card, but am sure it can't use xf86-video-intel or X modesetting.

Xwayland however will use the same driver as X.

Aur helpers : makepkg + my own local repo === rarely need them

What about the xf86-video-vesa package? Should/can I uninstall that too?

If you're using Gnome with Wayland there is still a high chance that you'll be using X via XWayland, as many apps still don't have working Wayland support (start with web browsers).
And yes, you need to remove xf86-video-vesa as well.

As an aside, why do you want to use modsetting?  My understanding is that performance is higher with xf86-video-intel.  Confirmed on my own system a little over a year ago.

The archi wiki, and many other arch forums talk about how the xf86-video-intel driver is obsolete or unmaintained, leading to lower performance and stuff. I too realised the improvement in performance after installing the intel video driver. So I'm not sure what that's all about?

As a side note,  installing xf86-video-intel driver definitely improves performance even in the wayland session. So this makes me think its not just an Xorg thing.

Also thanks for linking the benchmark tests! Appreciated!

Seem to be updated albeit slowly: https://cgit.freedesktop.org/xorg/drive … deo-intel/

EDIT: be objective and try the benchmark (and others too) using both drivers and draw your own conclusions about performance.
