Bug 105851 Xserver 1.20 RC2+ issues with Kwin + Present 1.2

[Mike Lothian]

Hi

Kwin doesn't seem to start with the following commit:

commit abb9b58d1af9a0286162e52ef9db390d0c950fc1
Author: Thierry Reding <treding at nvidia.com>
Date:   Fri Mar 16 14:24:21 2018 +0100

    present: Advertise protocol version 1.2

    Everything is implemented to support protocol version 1.2. Make it
    official.

Though I think the issue may lie in commit:

commit 6a5d51e0823b43280e3646b7a0c919a3b76146ea

    present: cap the version returned to the client

    As per the protocol, the server should not return version greater than
    the one supported by the client.

    Add a spec quote and tweak the numbers accordingly.

I realise that Kwin will probably need to be modified to work with
Present 1.2, but I don't think we should be seeing breakage unti that
happens

Regards

Mike
