Os desenvolvedores do projeto T2 Linux, que desenvolve um gerenciador de pacotes e plataforma para cria\u00e7\u00e3o de distribui\u00e7\u00f5es Linux, anunciaram a restaura\u00e7\u00e3o no X.Org Server do suporte \u00e0 arquitetura de acelera\u00e7\u00e3o 2D XAA (XFree86 Acceleration Architecture), criada em 1996 para ativar a acelera\u00e7\u00e3o de hardware em opera\u00e7\u00f5es com gr\u00e1ficos 2D no servidor X. O suporte ao XAA foi removido do servidor X em 2012, ap\u00f3s a transi\u00e7\u00e3o da maioria dos drivers DDX atuais para as arquiteturas EXA, SNA, GLAMOR ou UXA. <\/p>\n

O trabalho de restaura\u00e7\u00e3o do suporte ao XAA foi realizado com o objetivo de acelerar o funcionamento da distribui\u00e7\u00e3o em sistemas vintage e retro, al\u00e9m de esta\u00e7\u00f5es de trabalho cl\u00e1ssicas que eram fornecidas com sistemas Unix. A restaura\u00e7\u00e3o permitiu reintroduzir a possibilidade de utilizar acelera\u00e7\u00e3o 2D em sistemas com placas de v\u00eddeo muito antigas, que antes precisavam depender da renderiza\u00e7\u00e3o por software, uma vez que os drivers DDX para essas placas n\u00e3o suportam as arquiteturas de acelera\u00e7\u00e3o atuais. <\/p>\n

O suporte reintroduzido ao XAA foi testado com placas de v\u00eddeo ATi Mach-64, ATi Rage-128, SiS, Trident, Cirrus, Matrox (Millennium\/G450), Permedia2, Tseng ET6000 e Sun Creator\/Elite 3D. Observou-se que a utiliza\u00e7\u00e3o do XAA permitiu aumentar a suavidade na movimenta\u00e7\u00e3o das janelas, reduzir a carga no CPU e garantir suporte adequado ao framebuffer no modo TrueColor (24 bits por canal de cor).
