After upgrade tonight came out of Xorg to restart openbox.

I tried to start Xorg but it failed with "xf86OpenConsole cannot open /dev/tty0 ( no such file or directory)

/dev/tty0 was there so assumed permission problem. Temporarily added my user to tty group and tried again.

This time Xorg failed to start with "xf86OpenConsole cannot open Virtual Console 7 ( permisson denied.)

How to resolve?

Xorg.log below

Thanks
