====={{Anchor|GLAMOR}} Glamor=====
Glamor is a generic, hardware independent, 2D acceleration driver for the X server that translates the X render primitives into [[OpenGL]] operations, taking advantage of any existing 3D OpenGL drivers.<ref>{{cite web|title=What is Glamor?|url=http://www.freedesktop.org/wiki/Software/Glamor/|publisher=FreeDesktop.org|access-date=10 February 2014}}</ref> In this way, it is functionally similar to Quartz Extreme and QuartzGL (2D performance acceleration) for Apple [[Quartz Compositor]].

The ultimate goal of GLAMOR is to obsolete and replace all the DDX 2D graphics device drivers and acceleration architectures, thereby avoiding the need to write X 2D specific drivers for every supported graphic chipset.<ref>{{cite web|last=Anholt|first=Eric|title=Building 2D rendering acceleration with OpenGL|url=http://mirror.linux.org.au/linux.conf.au/2014/Wednesday/52-Building_2D_rendering_acceleration_with_OpenGL_-_Eric_Anholt.mp4|publisher=[[linux.conf.au]]|access-date=10 February 2014|archive-date=4 March 2016|archive-url=https://web.archive.org/web/20160304064444/http://mirror.linux.org.au/linux.conf.au/2014/Wednesday/52-Building_2D_rendering_acceleration_with_OpenGL_-_Eric_Anholt.mp4|url-status=dead}}</ref><ref>{{cite web|last=Packard|first=Keith|title=Brief Glamor Hacks|url=http://keithp.com/blogs/glamor-hacking/|access-date=7 March 2014}}</ref><ref>{{cite web |url=http://wiki.x.org/wiki/Events/XDC2013/XDC2013AdamJacksonGLXRewrite/ |title=Adam Jackson - GLX rewrite |date=24 September 2013 |access-date=2014-03-23}}</ref> Glamor requires a 3D driver with support for [[shader]]s.<ref>{{cite web |url=http://xorg.freedesktop.org/wiki/RadeonFeature/ |title=Radeon Feature Matrix |work=[[freedesktop.org]]}}</ref>
