Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your bug report is missing crash details. In order to debug a crash we will need a crash report. To create one, please follow these steps:

1. If you are not running a future development release of Ubuntu then apply the workaround from bug 994921.
2. If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport.
3. If the crash is in Xorg then uncomment this option from /etc/gdm3/custom.conf:
   # Additionally lets the X server dump core if it crashes
   #Enable=true
4. Reboot.
5. Reproduce the crash.
6. Look in /var/crash for crash files and when found, run:
   ubuntu-bug /var/crash/YOURFILE.crash
7. Add a comment here telling us the ID of the new bug that was created in step 6.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments, and doing so is also a security risk for yourself.
