gnome-shell at 100% after waking up from sleep, screen frozen

[Patrik Jelinko]

About 30% of the times when my computer wakes up from sleep/suspend, the screen is frozen. I can remotely login via ssh, and every time what I found is the gnome-shell process is using 100% CPU time. If I kill gnome-shell, it it takes me back to the login screen, and everything seems to be fine, I'm just loosing my session, which is quite annoying. Let me know if you need anything else, easy to reproduce the behaviour.

Patrik,

Please try this command to try and help us gather more information about the spinning process (while it is still spinning):

apport-cli -u 1749424 --hanging -P `pidof -s gnome-shell`

[Patrik Jelinko (pj7801)]

Daniel,

Can you pls double-check the command I need to run? It gives me the following error message:
---
xxxx@xxxxx:~$ apport-cli -u 1749424 --hanging -P `pidof -s gnome-shell`
Usage: apport-cli [options] [symptom|pid|package|program path|.apport/.crash file]

apport-cli: error: -u/--update-bug option cannot be used together with options for a new report
---
apport-cli --version
2.20.7
---

I have tried to play around with the options, but nothing seems to be working, always the same error message.

Thanks,
Patrik

Maybe try:

apport-cli --hanging -P `pidof -s gnome-shell`

If that then creates a new bug then please just tell us the new bug ID.

Hi Daniel,

I think I managed it now. First saved the record to a local file, then used the "apport-cli -u 1749424 filename" to send it. Pls check

[Daniel van Vugt (vanvugt)]

Thanks, but that's not what we need. Please avoid using '-u' and instead run:

  apport-cli --hanging -P `pidof -s gnome-shell`

If that creates a new bug then please just tell us the new bug ID.

[Patrik Jelinko (pj7801)]

Hi Daniel,

If I issue the command with --hanging, it would not give me a launchpad page to file a new report, and it kills the gnome-shell process.

I have issued it without --hanging, and opened a new bug, please check if you have enough info now:
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1749925

[Daniel van Vugt (vanvugt)]

Thanks, but we need a bug report that contains stack traces.

Next please try:

  kill -ABRT `pidof -s gnome-shell`

With some luck that will create a new crash file in /var/crash. You can then upload it to a new bug report using this command:

  ubuntu-bug /var/crash/YOURFILE.crash

[Patrik Jelinko (pj7801)]

Hi Daniel,

I have uploaded the crash dump for gnome-shell to #1750511

[Daniel van Vugt (vanvugt)]

Thanks. Let's continue in bug 1750511.
