[beagleboard] Re: fb rotate?
Just said in the post, if you read it all, it just rotates the fb not the EGL context. On Monday, September 9, 2019 at 2:08:52 AM UTC-4, H.

[beagleboard] Beaglebone Black EGL Screen rotation
Hi, Os: Linux beaglebone 4.14.108-ti-r108 #1 SMP PREEMPT Tue Jun 18 05:11:38 UTC 2019 armv7l GNU/Linux Egl :EGL vendor string: Imagination Technologies EGL version string: 1.4 build 1.14@3699939 (MAIN) EGL extensions: EGL_IMG_client_api_ogl EGL_KHR_image EGL_KHR_image_base EGL_KHR_gl_texture_2D_image EGL_KHR_gl_texture_cubemap_image EGL_KHR_gl_renderbuffer_image E GL_KHR_vg_parent_image EGL_IMG_cl_image EGL_KHR_fence_sync EGL_IMG_context_priority EGL_IMG_hibernate_process EGL_IMG_image_plane_attribs EGL_KHR_surfaceless_contex t EGL_KHR_wait_sync EGL_KHR_create_context EGL_WL_bind_wayland_display EGL_EXT_image_dma_buf_import EGL client APIs are: OpenGL_ES .. and much more I cannot get over with display going in portrait mode when rendering EGL full screen. I want to make the change permanent portrait mode. echo 1 > /sys/class/graphics/fbcon/rotate_all does rotate the fb as text and linux fb mode, but when using the QT on eglfs or EGL app;s like gles1test1 is allways landscape. Though the export QT_QPA_EGLFS_ROTATION=90 does nothing. Any help would be appreciated. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
