    Hi everybody!

    I want to switch from Qt 4.8 to Qt 5.1 but I figured out that QWS died in Qt 5.

    Formerly I used
    @[QTPROGRAMMNAME] -qws -display "multi: LinuxFB:/dev/fb0:0 LinuxFb:/dev/fb2:offset=1024,0:1 :0"@

    to set up two displays so that I could arrange multiple qt applications on these screens by using the QWS functions.
    What is now the equivalent for Qt5 and later?

    Every hint is highly appreciated!

    Best regards
    Florian

      Hi Florian,

      There is no real equivalent at the moment when it comes to using multiple displays at the same time.

      You can run the app with -platform linuxfb:fb=/deb/fbN to use a specific framebuffer device but you cannot specify multiple ones. For that, I have created https://bugreports.qt-project.org/browse/QTBUG-36114

      Cheers,
      Laszlo
