Bug Description

Binary package hint: input-utils

When I try to run lsinput on my Lenovo T410s multitouch-enabled laptop, I get the following error:

$ sudo lsinput
[sudo] password for oubiwann:
/dev/input/event0
protocol version mismatch (expected 65536, got 65537)

Feature Freeze Exception Information:

Input-utils is hard coded to an evdev protocol version at build time. The Maverick kernel has a backwards compatible evdev version bump. As it is, there no input-utils tools work at all. A simple rebuild makes them work again.

Just rebuilding would mean that older kernels will not work. The check should be changed to "version >= 0x010000".

Hi Dmitry,

This bug is only for the Ubuntu package (it's not obvious, but you can tell by the fact that the bug is against a package with "(Ubuntu)" in the name). Even more specifically, it's only a bug against the 10.10 version of Ubuntu.

As far as I can tell, the upstream source code is unmaintained. Since kernel versions will not change during the lifetime of a released version of Ubuntu, we don't really care too much about reworking this check for older kernels.

However, we will likely want to do something like this just for forward compatibility. I think there has been another version bump since 2.6.35, so we'll tackle this problem sometime during this Natty development cycle.

Thanks
