Kwanan nan Collabora ya buɗe uwar garken haɗaɗɗen wxrd, wanda aka aiwatar bisa ka'idar Wayland kuma an tsara shi don samar da tebur dangane da abubuwan xrdesktop a cikin mahalli na gaskiya na XNUMXD.
A matsayin tushe, ana amfani da ɗakin karatu na wlroots, wanda masu haɓaka yanayin yanayin mai amfani da Sway suka haɓaka, da kuma wxrc composite uwar garken, wanda aka tsara don amfani a cikin tsarin gaskiya na gaskiya.
Ba kamar maganin da aka fara samarwa a xrdesktop ba, wxrd yana ba da sabar na'ura ta musamman don mahalli na gaskiya, maimakon daidaita masu sarrafa taga da fata kwamfutar tafi-da-gidanka da ake da su don tsarin gaskiya na kama-da-wane (aikin xrdesktop yana ba da faci daban-daban don kwin da GNOME Shell, waɗanda ke buƙatar daidaitawa ga kowane sabon sakin waɗannan abubuwan).
Yin amfani da wxrd yana ba ku damar yin madubi ba kawai don madubi abun ciki na tebur mai girma biyu ba, a lokaci guda yayin da aka nuna shi akan na'ura ta al'ada, har ma don sarrafa windows da aka ƙaddamar musamman don tebur mai girma uku daban (wato, ba don samar da dama daga kwalkwali na VR zuwa tebur da aka yi amfani da shi a cikin tsarin na yanzu) da kuma samar da yanayi daban don kwalkwali na gaskiya).
Sabanin ayyuka iri ɗaya irin su Simula VR, Stardust, Motar Mota da Safespaces, uwar garken haɗaɗɗiyar wxrd an gina shi yana la'akari da ƙaramin abin dogaro da amfani da albarkatu. Wxrd kuma yana ba da damar yin aiki ba kawai tare da aikace-aikacen da ke kan ka'idar Wayland ba kuma yana ba da damar gudanar da aikace-aikacen X11 ta amfani da sabar xwayland DDX.
Tunda an haɓaka ƙa'idar Wayland don maɓallan madannai na kama-da-wane, shigar da bayanai zuwa wxrd ana aiwatar da su ta hanyar tsarin kwaikwayi na madannai wanda ke canza duk haruffan Unicode, gami da emoji, daga maballin kama-da-wane da aka bayar a xrdesktop.
wxrd yana buƙatar katin bidiyo wanda ke goyan bayan API ɗin Vulkan graphics da tsawo na VK_EXT_image_drm_format_modifier, Mai jituwa tare da Mesa daga sigar 21.1 (an haɗa da Ubuntu 21.04).
