Foi lan\u00e7ada a vers\u00e3o 6.0 do projeto Xpra, que desenvolve uma ferramenta semelhante ao screen e tmux para trabalhar com aplicativos gr\u00e1ficos. O Xpra permite executar aplicativos X11 em um sistema local ou remoto, desconectar a sess\u00e3o sem encerrar a execu\u00e7\u00e3o dos programas e voltar a trabalhar com os aplicativos ap\u00f3s algum tempo ou continuar a partir de outro host (\u00e9 poss\u00edvel come\u00e7ar a trabalhar com um programa em uma m\u00e1quina e continuar em outra). Por exemplo, o Xpra permite executar um aplicativo gr\u00e1fico em um servidor Linux externo e exibir o conte\u00fado na tela da esta\u00e7\u00e3o de trabalho atual, operando sob Linux, Windows ou macOS. O c\u00f3digo do projeto \u00e9 escrito em Python e distribu\u00eddo sob a licen\u00e7a GPLv2+. <\/p>\n

\u00c9 poss\u00edvel tanto conectar-se a sess\u00f5es de desktop existentes quanto criar novas sess\u00f5es para organizar o trabalho com programas gr\u00e1ficos do Linux em ambientes Windows e macOS. Al\u00e9m disso, o Xpra possui um cliente HTML5 integrado, permitindo conectar-se \u00e0s sess\u00f5es atrav\u00e9s do navegador. Al\u00e9m do acesso \u00e0s janelas, o Xpra implementa suporte para v\u00e1rias funcionalidades associadas a desktops, como transmiss\u00e3o de som para sistemas remotos, redirecionamento de impressoras e webcams, organiza\u00e7\u00e3o do acesso \u00e0 \u00e1rea de transfer\u00eancia, suporte \u00e0 sincroniza\u00e7\u00e3o do estado da bandeja do sistema e das notifica\u00e7\u00f5es. Existem fun\u00e7\u00f5es integradas para transfer\u00eancia e sincroniza\u00e7\u00e3o de arquivos entre sistemas.

\"Lan\u00e7amento<\/center>
\"Lan\u00e7amento<\/center> <\/p>\n

Entre os novos recursos introduzidos na vers\u00e3o 6.0 do Xpra, destaca-se o suporte \u00e0 arquitetura riscv64, a transi\u00e7\u00e3o para o uso do perfil b\u00e1sico do OpenGL, a adi\u00e7\u00e3o de um cliente separado para o GNOME, a implementa\u00e7\u00e3o do comando «xpra configure» para facilitar a configura\u00e7\u00e3o dos par\u00e2metros do Gstreamer, a acelera\u00e7\u00e3o das opera\u00e7\u00f5es mmap, a simplifica\u00e7\u00e3o da desativa\u00e7\u00e3o r\u00e1pida dos recursos expandidos para a transmiss\u00e3o de \u00e1udio e v\u00eddeo, e a adi\u00e7\u00e3o de suporte. para \u00e1reas de trabalho virtuais<\/a> Windows 10. <\/p>\n

Adicionalmente, destaca-se o projeto wprs, que desenvolve uma alternativa ao Xpra para sistemas baseados em Wayland. O Wprs permite executar aplicativos que utilizam Wayland em sistemas locais ou externos, e retomar o trabalho com eles em outros sistemas. Atrav\u00e9s da integra\u00e7\u00e3o com o XWayland, tamb\u00e9m \u00e9 poss\u00edvel executar aplicativos compilados para X11. Para operar em um sistema remoto, \u00e9 necess\u00e1rio iniciar um processo em segundo plano wprsd, ap\u00f3s o qual \u00e9 poss\u00edvel iniciar aplicativos de outros computadores usando os comandos «wprs run», «wprs detach» e «wprs attach». O c\u00f3digo do wprs \u00e9 escrito em Rust e \u00e9 distribu\u00eddo sob a licen\u00e7a Apache 2.0. <\/p>\n

O processo wprsd inclui a implementa\u00e7\u00e3o de um compositor servidor<\/a> Wayland, baseado na biblioteca Smithay, e em vez de renderizar na tela, realiza a serializa\u00e7\u00e3o da sess\u00e3o Wayland para transmitir a outra sistema. A sess\u00e3o \u00e9 recriada com a ajuda da ferramenta wprsc, que implementa um cliente Wayland baseado no Smithay Client Toolkit. Para autorizar o acesso e organizar o canal de comunica\u00e7\u00e3o, \u00e9 utilizado SSH. Entre as limita\u00e7\u00f5es do wprs, destaca-se o suporte apenas ao protocolo b\u00e1sico do Wayland e \u00e0s extens\u00f5es do XDG shell, o que, por exemplo, impede o uso da acelera\u00e7\u00e3o de hardware para renderiza\u00e7\u00e3o e dmabuf. Al\u00e9m disso, ainda n\u00e3o h\u00e1 suporte para a transmiss\u00e3o de eventos de telas sens\u00edveis ao toque\/touchpads e as capacidades da interface Drag&drop s\u00e3o limitadas.
