BBB + LCD3 Cape Boot Portrait Orientation

Question

Caveat: Total Newb. I know NOTHING about linux, but for my purposes I don't think much is needed (perhaps I am wrong, I am a Newb).

Recently got a BBB and LCD3 (TFT) cape. Flashed to latest angstrom so lcd3 would work, all good their.

Trying to make a kiosk if sorts.

I need the BBB to boot in portrait mode, rather than landscape.

How do I do this??

Any help would be greatly appreciated.

Basically you have to modify two files:

To set the screen orientation

"nano /etc/X11/xorg.conf"

Look for this section and add the line in bold (options are "CW" (90deg), UD (180deg), "CCW" (270deg)):

Section "Device"

Identifier "Builtin Default fbdev Device 0"

Driver "fbdev"

Option "Rotate" "CCW"

EndSection

Ctrl-X to exit nano and Enter to save without modifying the file name.

To set the touchscreen orientation:

"nano /usr/share/X11/xorg.conf.d/10-evdev.conf"

Look for this section and add the line(s) in bold (i set my screen CCW and had to swap both axes and invert the x-axis)

Section "InputClass"

Identifier "evdev touchscreen catchall"

MatchIsTouchscreen "on"

MatchDevicePath "/dev/input/event*"

Option "SwapAxes" "True"

Option "InvertX" "True"

Driver "evdev"

EndSection

Ctrl-X to exit nano and Enter to save without modifying the file name.

Tested on BBB + LCD3 Cape with Angstrom version 3.8.6
