In the cases when you can still move the cursor then that means gnome- shell has frozen but Xorg keeps working. But you might be experiencing multiple different problems. Regardless, the answer is the same :) ...
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. ** Summary changed: - Xorg freeze + Screen freeze ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1889013 Title: Screen freeze Status in gnome-shell package in Ubuntu: Incomplete Bug description: Everything is running smooth, I enjoy this software, but it all freezes up randomly. Sometimes I can still move the cursor, other times I cannot do anything but a hard reset. Do not know why, or haven't figured out what specifically I am doing when this happens. Usually just browsing the net or something simple like that when it happens.
