I think for me the framebuffer rotation is enough now. I have it rotated now after appending omapfb.rotate=1 omapfb.vrfb=y to kernel cmd line. But still i havent figured out two things: 1/ how to rotate the framebuffer on the fly? I tried: echo "1" > /sys/class/graphics/fb0/rotate according to this [1] but it does not work for me. 2/ i need to rotate also the touchscreen inputs. X server has options for it [2], but i would like to play some SDL games on direct framebuffer. I tried e.g. dosbox, scummvm, abuse - they all work great but the touchscreen needs to swap x and y. You can try e.g: export SDL_VIDEODRIVER=fbcon apt-get install scummvm scummvm Regards Radek [1] http://omappedia.org/wiki/Bootargs_for_enabling_display#Mirrorring_and_Rotation_of_OMAPFB [2] Option "Rotate" "cw" Option "SwapX" "true" ___ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community

I spent a while looking into this and my conclusion is that while the frame buffer does support rotation, the Xorg driver for the omap3 framebuffer doesn't hook into that. Also I couldn't find any evidence of ongoing development of the omap3 Xorg driver. So I'm guessing that to make 'xrandr' work on the GTA04 will take some fairly serious hacking in Xorg driver code. I wish I had time to do that ... though to be honest, if I did have the time I'd probably spend it on something else :-( NeilBrown signature.asc Description: PGP signature ___ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
