+ The <literal>nv</literal> and <literal>radeonhd</literal> drivers are

+ switch to a suitable kernel driver and the evdev X driver. For many
+ serial devices, the <command>inputattach</command> utility allows
+ attaching them to a Linux input device which can be recognized by the
+ <literal>evdev</literal> X driver.

+ <para>
+ Kernel drivers for Intel (starting from i830), ATI/AMD (from the
+ original Radeon to the Radeon HD 5xxx <quote>Evergreen</quote> series)
+ and for NVIDIA graphics chipsets now support native mode setting.

+ Support for old-style userspace mode setting is discontinued in the
+ <literal>intel</literal> X driver, which requires a recent kernel.
+ Users of custom kernels should make sure that their configuration
+ includes <literal>CONFIG_DRM_I915_KMS=y</literal>.

+ <section>
+ <title>Input device hotplug</title>
+ <para>
+ The Xorg X server included in Debian &release; provides improved support
+ for hotplugging of input devices (mice, keyboards, tablets, …). The old
+ <systemitem role="package">xserver-xorg-input-kbd</systemitem> and
+ <systemitem role="package">xserver-xorg-input-mouse</systemitem>
+ packages are replaced by <systemitem
+ role="package">xserver-xorg-input-evdev</systemitem>, which requires a
+ kernel with the <literal>CONFIG_INPUT_EVDEV</literal> option enabled.
+ Additionally, some of the keycodes produced by this driver differ from
+ those traditionally associated with the same keys. Users of programs
+ like <command>xmodmap</command> and <command>xbindkeys</command> will
+ need to adjust their configurations for the new keycodes.

+ <para>
+ Traditionally, the
+ <keycombo><keycap>Ctrl</keycap><keycap>Alt</keycap><keycap>Backspace</keycap></keycombo>
+ combination would kill the X server. This combination is no longer
+ active by default, but can be re-enabled by reconfiguring the
+ <systemitem role="package">keyboard-configuration</systemitem> package
+ (system-wide), or using your desktop environment's keyboard preferences
+ application.
