[nvidia] Xorg freeze

[tim474]

Sometimes there is an X11 freeze. Usually it happens when I connect to a Zoom conference, but latest (and at least one previous) it happened when I wasn't using Zoom. The symptoms were same: still image, but mouse cursor could be moved. I can switch to another terminal (ctrl+alt+f1), when I return to the GUI, there is only black screen with moving mouse cursor.

I can only restart lightdm.

[Daniel van Vugt (vanvugt)]

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.

Sorry, there are not crashes at this time.

But my last freeze was on May 27.

[Daniel van Vugt (vanvugt)]

In that case please:

1. Reproduce the freeze again.

2. Reboot.

3. Run:

   journalctl -b-1 > prevboot.txt

   and attach the resulting text file here.

[tim474 (tim474)]

Here is journalctl output in a freeze time. I have only changed some IP address for xx.xx.xx.xx and my username/hostname

[Daniel van Vugt (vanvugt)]

There's not much in that file. Please use the full steps in comment #4.

[tim474 (tim474)]

The freeze was about May 27 19:32:32, when I had opened software-properties utility.

[Daniel van Vugt (vanvugt)]

I don't know about 19:32:32 but it sounds like Xorg might have crashed around 19:44:04 and 20:25:10.

So please repeat the steps in comment #2.

Also if you can find your Xorg.log file from when a crash/freeze happened then please attach that.
