Christian Schaller, l\u00edder do grupo de desenvolvimento de sistemas desktop na Red Hat e na Fedora Desktop Team, na revis\u00e3o dos planos<\/a><\/noindex>, relativos aos componentes de desktop no Fedora 31, mencionou a inten\u00e7\u00e3o da Red Hat de interromper o desenvolvimento ativo das funcionalidades do servidor X.Org, limitando-se apenas \u00e0 manuten\u00e7\u00e3o da base de c\u00f3digo existente e \u00e0 corre\u00e7\u00e3o de erros.<\/p>\n

Atualmente, a Red Hat desempenha um papel fundamental no desenvolvimento do servidor X.Org e assume sua manuten\u00e7\u00e3o. Portanto, caso se afaste do desenvolvimento, \u00e9 pouco prov\u00e1vel que a forma\u00e7\u00e3o de vers\u00f5es significativas do servidor X.Org continue. No entanto, apesar da interrup\u00e7\u00e3o do desenvolvimento, a manuten\u00e7\u00e3o do X.Org pela Red Hat continuar\u00e1 pelo menos at\u00e9 o fim do ciclo de vida da distribui\u00e7\u00e3o RHEL 8, que ir\u00e1 at\u00e9 2029.<\/p>\n

A estagna\u00e7\u00e3o no desenvolvimento do servidor X.Org j\u00e1 \u00e9 vis\u00edvel \u2014 apesar do ciclo de lan\u00e7amento de seis meses que foi utilizado anteriormente, a \u00faltima vers\u00e3o significativa, X.Org Server 1.20, foi lan\u00e7ada h\u00e1 14 meses, e o desenvolvimento da vers\u00e3o 1.21 est\u00e1 emperrado. A situa\u00e7\u00e3o pode mudar se alguma empresa ou comunidade assumir a responsabilidade pela continuidade da adi\u00e7\u00e3o de funcionalidades ao servidor X.Org, mas, considerando o deslocamento generalizado de projetos significativos em dire\u00e7\u00e3o ao Wayland, \u00e9 improv\u00e1vel que hajam interessados.<\/p>\n

Atualmente, a Red Hat est\u00e1 focada na melhoria do desktop baseado em Wayland. A transi\u00e7\u00e3o do servidor X.Org para um modo de manuten\u00e7\u00e3o \u00e9 esperada ap\u00f3s resolver a tarefa de eliminar completamente a depend\u00eancia dos componentes do X.Org e garantir o funcionamento do GNOME Shell sem o uso do XWayland, o que requer refatora\u00e7\u00e3o ou remo\u00e7\u00e3o dos v\u00ednculos restantes ao X.Org. Esses v\u00ednculos j\u00e1 foram quase eliminados do GNOME Shell, mas ainda permanecem no daemon GNOME Setting. No GNOME 3.34 ou 3.36, a inten\u00e7\u00e3o \u00e9 eliminar completamente os v\u00ednculos com o X.Org e organizar o funcionamento do XWayland de forma din\u00e2mica<\/a><\/noindex>, quando necess\u00e1rio, para fornecer componentes que garantam compatibilidade com o X11.<\/p>\n

Tamb\u00e9m \u00e9 mencionada a necessidade de resolver uma s\u00e9rie de problemas remanescentes<\/a><\/noindex> com Wayland, como trabalhar com drivers propriet\u00e1rios da NVIDIA e aprimorar o servidor DDX do XWayland para garantir a execu\u00e7\u00e3o eficiente de aplicativos X em um ambiente baseado em Wayland. Entre as atividades realizadas no \u00e2mbito da prepara\u00e7\u00e3o do Fedora 31, destaca-se a implementa\u00e7\u00e3o na funcionalidade do XWayland que permite a execu\u00e7\u00e3o de aplicativos X com privil\u00e9gios de root. Tal execu\u00e7\u00e3o \u00e9 question\u00e1vel do ponto de vista de seguran\u00e7a, mas \u00e9 necess\u00e1ria para a compatibilidade com programas X que requerem trabalho com privil\u00e9gios elevados. <\/p>\n

Outra tarefa \u00e9 melhorar o suporte ao Wayland na biblioteca SDL, por exemplo, para resolver problemas de escalonamento ao executar jogos antigos que funcionam em resolu\u00e7\u00f5es de tela baixas. Tamb\u00e9m \u00e9 ressaltada a necessidade de aprimorar o suporte ao Wayland em sistemas com drivers propriet\u00e1rios da NVIDIA \u2014 se o Wayland j\u00e1 pode funcionar sobre esses drivers h\u00e1 tempos, o XWayland, nessa configura\u00e7\u00e3o, ainda n\u00e3o consegue utilizar os recursos para acelera\u00e7\u00e3o de hardware 3D (planeja-se oferecer a op\u00e7\u00e3o de carregamento do driver x.org da NVIDIA para o XWayland).<\/p>\n

Adicionalmente, continua o trabalho de substitui\u00e7\u00e3o do PulseAudio e Jack por um servidor multim\u00eddia PipeWire<\/a><\/noindex>, ampliando as capacidades do PulseAudio com funcionalidades para lidar com fluxos de v\u00eddeo e processamento de \u00e1udio com atrasos m\u00ednimos, tendo em vista a necessidade de sistemas de processamento de \u00e1udio profissional, al\u00e9m de oferecer um modelo de seguran\u00e7a avan\u00e7ado para gerenciar o acesso a n\u00edvel de dispositivos individuais e fluxos. No ciclo de desenvolvimento do Fedora 31, o foco est\u00e1 no uso do PipeWire para organizar o compartilhamento de tela em ambientes baseados em Wayland, inclusive utilizando o protocolo Miracast<\/a><\/noindex>.<\/p>\n

\"A<\/a><\/noindex><\/center><\/p>\n

No Fedora 31 tamb\u00e9m est\u00e3o programados<\/a><\/noindex> adicionar a capacidade de executar aplicativos Qt em uma sess\u00e3o do GNOME baseada em Wayland utilizando o plugin Qt Wayland em vez do plugin XCB, que utiliza X11\/XWayland.<\/p>\n
