Progetto NetBSD ha annunciato<\/a><\/noindex> sul cambiamento del gestore delle finestre predefinito nella sessione X11 con twm<\/a><\/noindex> con CTWM<\/a><\/noindex>. CTWM \u00e8 un fork di twm, nato nel 1992, sviluppato per creare un gestore delle finestre leggero e completamente personalizzabile, che consente di modificare l'aspetto e il comportamento secondo il proprio gusto.<\/p>\n

Il gestore delle finestre twm \u00e8 stato offerto in NetBSD per gli ultimi 20 anni, e nelle condizioni attuali appare obsoleto. La reazione negativa degli utenti nei confronti del twm predefinito ha spinto gli sviluppatori a rivedere l'interfaccia predefinita e ad adottare un gestore delle finestre pi\u00f9 funzionale, CTWM, per creare un ambiente pi\u00f9 amichevole per gli utenti provenienti da altri sistemi operativi. <\/p>\n

CTWM supporta desktop virtuali, \u00e8 in continua evoluzione e viene fornito sotto una licenza compatibile con NetBSD. Tra le nuove funzionalit\u00e0 implementate su CTWM, si segnalano il menu delle applicazioni generato automaticamente, utili combinazioni di tasti per un controllo completo senza mouse, l'adattamento per il lavoro con diverse risoluzioni dello schermo (compresi HiDPI con l'aggiunta di font di grandi dimensioni) e la possibilit\u00e0 di supportare sia sistemi molto lenti che molto veloci tramite un unico file di configurazione. <\/p>\n

Inoltre pubblicata<\/a><\/noindex> nota sullo stato del progetto per garantire il funzionamento del server composito in NetBSD swc<\/a><\/noindex> basato sul protocollo Wayland. Il porting non \u00e8 ancora pronto per un uso quotidiano, ma \u00e8 gi\u00e0 idoneo per esperimenti e per l'esecuzione di applicazioni che utilizzano Qt5, GTK3 o SDL2. Tra i problemi si segnala l'incompatibilit\u00e0 con alcune applicazioni, inclusi Firefox, la mancanza di supporto per l'esecuzione di applicazioni X11 e la possibilit\u00e0 di funzionare solo con GPU Intel, per le quali \u00e8 disponibile un driver per la commutazione delle modalit\u00e0 video a livello di kernel.<\/p>\n

Tra le caratteristiche di Wayland che rendono difficile il porting su NetBSD c'\u00e8 la presenza di una grande quantit\u00e0 di codice specifico per il sistema operativo nei gestori di composizione, responsabili della gestione dello schermo, dell'input e della gestione delle finestre. Wayland non offre protocolli pronti per funzionalit\u00e0 come la creazione di screenshot, il blocco dello schermo e la gestione delle finestre, e attualmente \u00e8 in ritardo rispetto al server X in aree come portabilit\u00e0, modularit\u00e0 e standardizzazione.<\/p>\n

Funzionalit\u00e0 aggiuntive vengono implementate dal gestore di composizione o attraverso la definizione di estensioni ai protocolli. Il server di composizione di riferimento Weston \u00e8 fortemente vincolato all'API del kernel Linux. Ad esempio, il legame con il meccanismo di multiplexing input-output epoll richiede una revisione per supportare kqueue. I patch per utilizzare kqueue sono gi\u00e0 stati preparati dagli sviluppatori dei sistemi BSD, ma non sono ancora stati accettati nel codice principale. <\/p>\n

I rappresentanti di NetBSD intendono convincere gli sviluppatori di Wayland a non utilizzare un legame rigido con epoll, ma a passare a un'interfaccia universale, come libevent. Tra i lavori programmati \u00e8 anche prevista l'aggiornamento dello stack DRM\/KMS del kernel di NetBSD e dei driver grafici, incluso il porting del codice dal kernel Linux, oltre all'aggiunta del supporto per il cambio atomico delle modalit\u00e0 video, nuove versioni di DRM e API Glamor (per eseguire applicazioni X11 sotto xwayland). \u00c8 previsto l'aggiunta del supporto per i frame buffer al server composito basato su Wayland.<\/p>\n
