Vitaly Minko to slouken Hi all, I wrote a patch, which allows user to rotate the screen in case of fbcon driver. The rotation angle is controlled by SDL_VIDEO_FBCON_ROTATION environment variable and possible values are: not set - Not rotating, no shadow. "NONE" - Not rotating, but still using shadow. "CW" - Rotating screen clockwise. "UD" - Rotating screen upside down. "CCW" - Rotating screen counter clockwise. The patch is based on wscons driver, written by Staffan Ulfberg. I tested it on Device: Sharp Zaurus SL-C1000 SDL version: 1.2.13 Kernel version: 2.6.24.4 Best regards, Vitaly.
