Resuming resets my session

[Nicolas_Raoul]

I installed 18.04 from scratch a day after it got released.

Twice per day I close the lid of my laptop and open it again after. Usually it immediately asks me for the password and brings me back to what I was doing.

But 3 times so far, it took a minute before showing me a login screen (like if I had not yet a session) asking me to choose my user (there is only one user), then enter my password. It then starts to load... and asks me for my password AGAIN. Then it shows my desktop, but everything I was doing before is gone, no more open windows. When I start Firefox it asks me whether I want to restore my tabs. When I open Byobu it shows my tabs as I left them.

Sounds like you have two bugs.

Asking for the password twice is bug 1765261.

But it sounds like you also have a crash causing your lost session so...

-----

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.

Actually asking for the password twice in "then enter my password. It then starts to load..." might also be another shell/session crash. Regardless, please follow the above instructions.

[Nicolas_Raoul (nicolas-raoul)]

Thanks Daniel!
1. Done, commented out the line in /etc/apport/crashdb.conf
2. It was already set to enabled=1
3. Done, commented out the line in /etc/gdm3/custom.conf
4. Doing it after posting this
5. OK, I will continue next time the bug happens, it might take a week or so :-)

[Nicolas_Raoul (nicolas-raoul)]

The crash just happened again, and here are 3 fresh new files in my /var/crash, whose date matches exactly the time of the crash:

_usr_lib_xorg_Xorg.1000.crash
_usr_bin_Xwayland.120.crash
_usr_bin_gnome-shell.120.crash

About the first one I submitted this bug and marked it as a duplicate:
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1772362

About the second one a bug already existed, confirmed with "Medium" importance:
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1731911

About the third one I was told that I have out-of-date packages, I am updating now. Please note that this is a fresh install of the recently released 18.04, and updates are set to "weekly" so it can't be crazy old either :-)

[Expired for xorg-server (Ubuntu) because there has been no activity for 60 days.]

[Nicolas_Raoul (nicolas-raoul)]

This keeps happening every two-three times I close then open my laptop's lid. It means I lose my work, running VMs, etc, about 3 times per work week.

If there is anything I can do to help solve this bug please let me know, thanks!

[Daniel van Vugt (vanvugt)]

Thanks for the crash reports. This issue should be dealt with in those bugs since they contain the crash details.
