Bug Description
Freezes randomly without any traceable pattern. Windows become unresponsive while the cursor works.
To unfreeze I have to press the OFF button of my HP ProBook and then click on "Cancel" in the shutdown dialogue. That unfreezes the windows. May happen several times per session, may not happen at all.

If the cursor still works then that's Xorg which is still working and only gnome-shell has frozen or crashed, so...
Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https:/ /errors. ubuntu. com/user/ ID where ID is the content of file /var/lib/ whoopsie/ whoopsie- id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.
