OS: Ubuntu 18 Qt: 5.15.1 GCC x64
I tried
qDebug()<<"screens"<<QGuiApplication::screens();
xcb which shows:
screens (QScreen(0x55ab206fba50, name="HDMI-0"), QScreen(0x55ab206fba90, name="DVI-D-0"))
but on eglfs which shows:
screens (QScreen(0x55c07f8308f0, name=""))
backend used
eglfs_x11
, then I tiredeglfs_kms_egldevice
the app even cannot enter main function gaveCould not open DRM (NV) device
