diff between starting X server on client with/without OpenGL enabled

If virtualbox-ose-additions 5.0.26 is built with OpenGL support, the X server
in the client cannot start.

The attached diff compares /var/log/Xorg.0.log (without OpenGL support) to
/var/log/Xorg.0.log.old (with OpenGL support):

    diff =(sed 's/^\[..........\] //' /var/log/Xorg.0.log) =(sed
's/^\[..........\] //' /var/log/Xorg.0.log.old)

With the 4.3.38 version, enabling OpenGL support did not prevent starting of
the X server.

Furthermore, with the 5.0.26 version, issuing the command

    VBoxManage controlvm 'FreeBSD 10 i386 (v905)' setvideomodehint 1728 972 32

is honored only after logging in to the client machine. If I remember
correctly, the same command would already resize the login screen (KDE) with
the 4.3.38 version.
