Same problem here (I think): I just updated my Fedora 22 from kernel 4.0.4 to 4.2.3, and now the X windows system does not work: after issuing the "startx" command all I get is a black screen, no mouse, nothing. Kernel 4.0.4 still works.
(...which makes me wonder, does Parallels have an official list of supported Linux kernels somewhere?)
