the header xcb/xinput.h is missing

Bug #1777994 reported by Shawn Rutledge on 2018-06-21
This bug affects 2 people
Affects Status Importance Assigned to Milestone
libxcb (Ubuntu)

Bug Description

Allow Qt 5.12 to be compiled with full input support. This allows applications to be built using complex input devices such as drawing pads. This is used in e.g Krita which KDE builds into a Snap package for distribution. Currently Krita does not work with pen input devices with pressure sensitivity.

[Test Case]
Install Krita with Qt 5.12 from current Snap and note how pressure sensitivity does not work.

[Regression Potential]
None that I can see, it's just packaging a few new header files.


I suspect this means there should be another package, libxcb-xinput-dev perhaps?

I already did sudo apt install "libxcb*dev" to get all related dev packages, but none of them provide xcb/xinput.h.

The result is that when building Qt from source, it's necessary to use a copy of this file which Qt provides (qtbase/src/3rdparty/xcb/include/xcb/xinput.h), because it's missing from the system. So if you don't give the option -qt-xcb to configure, then Qt will be built without multi-touch support.

An upload of libxcb to bionic-proposed has been rejected from the upload queue for the following reason: "Should not use a non-existent Debian version, but instead reflect reality with 1.13-2~ubuntu18.04".

Hello Shawn, or anyone else affected,

Accepted libxcb into bionic-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

testing on bionic with bionic-proposed enabled

I can successfully install libxcb-xinput-dev and libxcb-xinput0 and they contain the necessary files. I can install libxcb* and it includes the same files as before.
