I have seen this error on two machines as well, and, as mentioned above,
making /usr/lib/xorg/Xorg suid "resolves" it. In both cases the
"radeon" kernel module was involved. I straced it and I saw that some
system call got an access denied.

On two other machines I had X but no mouse and no keyboard after this
"upgrade". To resolve this I had to make the user member of the group
"input". After that, the mouse and keyboard worked properly again.

Normally X is started by gdm or whatever, so for most people X will work
properly. But this issue is a problem for those who start X as a normal
user, so there will be few people who encounter this rather annoying
problem.

BTW: systems mentioned above are systemd-free.

I have the same problem here but my error is different.

xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)

Before "upgrading", I could startx/xinit as a user no problem. After
"upgrading", no. It only works when using sudo or as root.
