Vivante: trying to rotate display in xorg.conf: Assert Failed

Question asked by Michael Burr on Jan 30, 2017

Trying to set up xorg.conf to rotate the display 90 degrees. Everything works fine when screen rotation is "normal" (i.e. landscape mode). Manually changing orientation via "xrandr -o left" at the command line also works fine. But use the "Rotate" option in xorg.conf and the Vivante driver chokes, saying "Assertion `key->initialized' failed."


Anyone know what's wrong?
