[arch-general] xorg-server 1.6.0 in testing

[Jan de Groot]

The upcoming version of xorg-server will have a lot of workarounds and
patches removed. Doing so, the package becomes easier to understand, as
even its maintainer has no idea what is happening anymore. When
upgrading to xorg-server-1.6, you will see these file conflicts on most
systems:

error: failed to prepare transaction (conflicting files)
xorg-server: /usr/lib/xorg/modules/extensions/libdri.so exists in
filesystem
xorg-server: /usr/lib/xorg/modules/libwfb.so exists in filesystem

It's safe and advised to overwrite these files. The symlinks were
previously created from post_install by the xorg-server and nvidia-utils
packages. It is advised to install xorg-server first by using "pacman
-Sf xorg-server", after which you can upgrade the rest of your system.

This release of xorg-server requires a rebuild of all video and input
drivers. Older drivers will fail to load with an ABI mismatch. Drivers
in our repositories will receive an update to match the xorg-server ABI.

Nvidia has updated their latest drivers with support for this version of
xorg-server. AMD does not support xorg-server-1.6 yet in their Catalyst
drivers. AMD users are advised to switch to the xf86-video-ati or
xf86-video-radeonhd drivers instead, or keep any X.Org related updates
on hold via IgnorePkg in pacman.conf. This can be done by putting
xorg-server in IgnorePkg in pacman.conf. All other updates should have
conflicts set, so it will be clear which additional packages should be
added to the IgnorePkg list on your system. Note that there will be no
support for older versions of xorg-server when this version moves to
extra.
