• # un écran 8" affiché à 59"

    Posté par (Mastodon) . En réponse au journal lsdisplay / lsgpu — lister écrans et GPUs depuis le terminal dans l'esprit de lspci, lscpu, lsusb: v.0.1.0 appel à tests. Évalué à 1 (+0/-0).

    GPU NVIDIA + Intel, KDE Wayland également, donc pas de surprise, ça fonctionne,

    Mais un écran un peu exotique : écran 8" intégré dans le boitier PC (Jonsbo D31),
    qui se retrouve affiché à 59"
