What about XInput2.4?

What about XInput2.4?

This should be integrated in xorg-server 21.1.2. XInput is not the xinput package, if that's what you're thinking (that one's still at the version we're currently packaging)

[dkwo]

indeed:

This is the first release candidate of Xorg 21.1.0 release.
Notable changes since 1.20 include:

• The meson support is now fully mature. While autotools support will still be
  kept for this release series, it will be dropped afterwards.

• Glamor support for Xvfb.

• Variable refresh rate support in the modesetting driver.

• XInput 2.4 support which adds touchpad gestures.

• DMX DDX has been removed.

• X server now correctly reports display DPI in more cases which may affect
  rendering of client applications on hi-DPI screens.

A large number of small features and various bug fixes.

Note that since 21.1 series XWayland is released separately and thus this
release does not include it.

Rebased and pushed a couple more updates, as in https://who-t.blogspot.com/2021/09/whats-new-in-xi-24-touchpad-gestures.html

I'm confused, it all builds fine locally using update-bulk.

[dkwo]

It fails on ci with
Dependency inputproto found: NO found 2.3.2 but need: '>= 2.3.99.1'
while here I get correctly
Run-time dependency inputproto found: YES 2.3.99.2
which is provided by xorgproto.

[dkwo]

Now it mysteriously builds again in ci.

I think xf86 drivers will need to be revbumped for this.

[dkwo]

Do you mean xf86-input* and xf86-video* ?

[dkwo]

Revbumped all, added a couple of patches stolen from arch/alpine.
It seems to work fine on my system.

[dkwo]

Patches were taken from upstream: either pull requests, or already merged into master.
Only exception is xf86-video-fbturbo*, which has not seen changes since 2015 and unsurprinsingly fails to build with recent xorg.
There's an issue on its github ssvb/xf86-video-fbturbo#66 I'm not sure what to do with this.

[dkwo]

Also, in some cases I took only patches that allow to build, but judging from the commits' titles more patches may be needed for using the pkgs.

[dkwo]

The package xf86-video-fbturbo* not only is obsolete, but it also seems not very usefull/not working in present condition,
see e.g. https://new.reddit.com/r/voidlinux/comments/rtkdhd/display_server_on_rpi4_using_aarch64/
@Piraty Shall I just remove it?

[dkwo]

Updated to a new xorg version and rebased onto master.
This is ready for review.

[abenson]

nvidia and nvidia390 are likely blockers until they're updated for the ABI bump.

It looks like they should, I'm double checking.

[dkwo]

Done. It should be fine now.

Now installs like a charm, thanks!

Can confirm that this works for me (on xmonad). Further, I was also able to build the Emacs master branch with the --with-xinput2 flag just fine, to make use of new modes that need XInput 2.4 features
