X crashes on some runs of Kubuntu live image returning in SDDM login

Looking at the logs this isn't a fault with SDDM but X is crashing on login returning us to SDDM

Status changed to 'Confirmed' because the bug affects multiple users.

I have similar problems with latest Ubuntu Vivid daily build (2015-04-16: http://cdimage.ubuntu.com/daily-live/current/vivid-desktop-amd64.iso) installed on USB media. In boot I see messages "invalid user: ubuntu ubuntu".

Please:
  1. Report to <https://bugs.freedesktop.org/>.
  2. Paste the new report URL here.
  3. Set this bug status back to "confirmed".

Thank you.

Is that still true on current vivid daily images?

Today it doesn't even return to an sddm login. There is a crash for kactivitymanagerd in bug 1446725 which happens at the same time as the X crash.

I do still get this on today's daily on my Thinkpad "Intel Corporation Core Processor Integrated Graphics Controller (rev 02)". It's still fine on my Sony Vaio

Asus g73jh a1 upgrade from 14.02.2. -> 14.10 -> 15.04 No Login screen but can acess tty's if need any other information please let me know

Hello, I am having similar issue with an installation(not live), after logging in, while desktop is loading, something crashes and takes me back to sddm login. Is there any log file I should check?

I believe I am also seeing the same thing. A live image present me with a choice to try or install and 'try' results in a blank screen (hard crash?) with no ttys available.

Status changed to 'Confirmed' because the bug affects multiple users.
