[Benedikt <1435898@xxxxxxxxxxxxxxxxxx>]

I have tested the 3.18 kernel from the repo and the problem remains. The
oops messages are also the same. Since kde has worked with 3.18 in the
past this seems very odd.

I have tried to reset the settings in kde and see if that helps, but no
luck with that.

It could be that the kernel oops are only fatal to kde with the latest
kde updates. Or it could be that the kernel oops are completly unrelated
to my login problem ...

Do you have an idea what I could do to localize the problem?

Title:
  Can not start (kde5) Desktop: Intel driver Failure

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Kubuntu 15.04 start without problems to the display manager sddm. If I
  enter my password the display is blank for a second and then does
  kubuntu load forever the desktop environment.

  Dmesg shows several oopses in the intel driver:

  invalid max DP link bw val 0, using 1.62Gps

  and

  compute-config() on unknown output!

  I think this problem occurs since the update to 3.19.0-9.

  Kernel 4.0-rc5 tested with the same problem.
