X Server
General Information
Be sure so recompile input/video drivers like nvidia-drivers and xf86-input-evdev against the new server ABI when upgrading.
When there are no available nvidia-drivers which support the recent X.Org Server release are out you can try to pass the -ignoreABI switch to X, for example the configuration for KDE.
X.Org Server 1.7
Releases prior to 1.8 made use of HAL for input device configuration.
X.Org Server 1.8
This release features udev input device management (HAL will be deprecated in future releases), it also adds xorg.conf.d directory support to simplify configuration. You no longer need a /etc/X11/xorg.conf or the previous HAL .fdi files.
X.Org Server 1.8 is supported by nvidia drivers >=195.36.24.
