Udgivet er udgaven af projektet Xpra 6.0, der udvikler en lignende funktionalitet som v\u00e6rkt\u00f8jerne screen og tmux til at arbejde med grafiske applikationer. Xpra g\u00f8r det muligt at k\u00f8re X11-applikationer p\u00e5 et lokalt eller fjernsystem, adskille sessionen uden at afslutte programmets k\u00f8rsel og vende tilbage til arbejdet med applikationerne efter noget tid eller forts\u00e6tte arbejdet fra en anden v\u00e6rt (man kan begynde at arbejde med et program p\u00e5 \u00e9n maskine og forts\u00e6tte p\u00e5 en anden). For eksempel giver Xpra mulighed for at k\u00f8re en grafisk applikation p\u00e5 en ekstern Linux-server og vise indholdet p\u00e5 sk\u00e6rmen af den nuv\u00e6rende arbejdsstation, der k\u00f8rer Linux, Windows eller macOS. Koden til projektet er skrevet i Python og distribueres under GPLv2+ licensen. <\/p>\n

Det er muligt b\u00e5de at tilslutte til eksisterende desktopsessioner og oprette nye sessioner for at organisere arbejdet med grafiske Linux-programmer i Windows- og macOS-milj\u00f8er. Desuden har Xpra en indbygget HTML5-klient, der tillader tilslutning til sessioner via en browser. Udover adgang til vinduer i Xpra har det ogs\u00e5 st\u00f8tte for mange tilknyttede funktioner fra desktop-milj\u00f8er, s\u00e5som transmission af lyd til det fjernsystem, omdirigering af printere og webkameraer, organisering af adgang til udklipsholderen, st\u00f8tte til synkronisering af status for systembakken og notifikationer. Der er indbyggede funktioner til at overf\u00f8re og synkronisere filer mellem systemer.

\"Udgivelse<\/center>
\"Udgivelse<\/center> <\/p>\n

Bland de nye funktioner, der er blevet tilf\u00f8jet i version Xpra 6.0, kan n\u00e6vnes underst\u00f8ttelse af riscv64-arkitektur, skift til brug af det grundl\u00e6ggende OpenGL-profil, tilf\u00f8jelse af en separat klient til GNOME, implementering af kommandoen «xpra configure» for at forenkle ops\u00e6tningen af Gstreamer-parametre, acceleration af mmap-operationer, forenkling af hurtig frakobling af avancerede funktioner til lyd- og videotransmission samt tilf\u00f8jelse af underst\u00f8ttelse. for virtuelle skriveborde<\/a> Windows 10. <\/p>\n

Derudover kan projektet wprs n\u00e6vnes, som udvikler en tilsvarende l\u00f8sning til Xpra for Wayland-baserede systemer. Wprs muligg\u00f8r k\u00f8rsel af applikationer, der bruger Wayland, p\u00e5 et lokalt eller eksternt system og genoptager arbejdet med dem p\u00e5 andre systemer. Gennem integrationen af XWayland sikres muligheden for at k\u00f8re applikationer, der er bygget til X11. For at arbejde p\u00e5 et fjernt system skal den baggrundsproces wprsd startes, hvorefter applikationer kan k\u00f8res fra andre computere ved hj\u00e6lp af kommandoerne «wprs run», «wprs detach» og «wprs attach». Koden til wprs er skrevet i Rust og distribueres under Apache 2.0-licensen. <\/p>\n

Processen wprsd inkluderer implementeringen af komposition server<\/a> Wayland, der er baseret p\u00e5 Smithay-biblioteket, udf\u00f8rer ikke rendering p\u00e5 sk\u00e6rmen, men i stedet serialisering af Wayland-sessionen til dens overf\u00f8rsel til et andet system. Sessionen genskabes ved hj\u00e6lp af v\u00e6rkt\u00f8jet wprsc c med en Wayland-klient baseret p\u00e5 Smithay Client Toolkit. SSH bruges til autorisering af adgang og organisering af kommunikationskanalen. Som begr\u00e6nsninger n\u00e6vnes, at wprs kun underst\u00f8tter den grundl\u00e6ggende Wayland-protokol og XDG shell-udvidelser, hvilket for eksempel ikke muligg\u00f8r brug af hardware-accelereret rendering og dmabuf. Derudover underst\u00f8ttes der i \u00f8jeblikket ikke transmission af h\u00e6ndelser fra ber\u00f8ringssk\u00e6rme\/touchpads, og drag & drop-gr\u00e6nsefladens muligheder er begr\u00e6nsede.
