How-To: Change OS Screen Orientation via /system/build.prop

[lestofante]

here my adventure:

Code:

adb connect [ip address of tinkerboard]
adb root
adb connect [ip address of tinkerboard]
adb remount
adb pull /system/build.prop .

here i wanted in potrait mode, so i set

Code:

ro.sf.hwrotation=90

and uploaded back the file with

Code:

adb push build.prop /system

then i also had to run

Code:

adb shell "setprop persist.demo.hdmirotation portrait"

and finally add the fix for the touch  from the previus post of jamess with

Code:

adb push libandroid_servers.so /system/lib

finally rebooted the device (well, actually i reboted at every step and every step i found something new xP)

Code:

adb reboot

now i have only a couple of issue left:

1: the virtual button bar does NOT resize correctly and the buttons seems to be pushed on the right
2: the touch does not responde well. I tested with a touch test app, and seems the touch itself is quite good, is the os that is... laggy

Next step for me in integration of a standard NMEA, or maybe even of a AGPS.. any suggestion? I already have a "standard" serial UBLOX

Tested on V13.12.0.43; please note previus version the touchescreen did NOT work (1024*768)
