I'm having the same problem on an up to date 15.10. Only I cannot log back in because there's no display manager present. I can switch to a virtual console and there it works. But when I get back to Console #7 the display goes into power saving mode. The only trace from the crash is in dmesg:

Over DVI it works fine - I can switch my display off and on again without problems. I have a Z87 MB with Pentium G3258 using the integrated graphics of the CPU.
