Hi:
I want to know to how set DPI in linux 4.9.88_2.0.0 system.
a 10-inch screen to display weston desktop with lvds signal .Through a mipi to lvds IC.
when run the qt5`s example I found the font size is very small . I search the environment ,but not find the similar value such as export QWS_DISPLAY . Can anyone tell me how to set it.
Hello coin,
export QT_EGLFS_NO_FB_MULTI_BUFFER=1
if it is Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters)
Regards.
