QT5.10 LinuxFB with DRM
-
Hello,
I am trying to utilize the DRM with linuxFB on an AM3352 processor. We are using linuxFB as this version of the processor has no graphics core. The app runs fine with QT_QPA_FB_DRM=0 and utilizes the resolution set in uboot. The issue is when i set QT_QPA_FB_DRM=1 the application starts but the resolution goes to the maximum supported value. I can not find any documentation of how to set the resolution with the DRM enabled linuxfb. I tried setting QT_QPA_EGLFS_KMS_CONFIG to a json file but this had no effect on resolution. Is there a method or environmental variable to set this in a similar way?
