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.
