[Bug 1685141] Re: System freezes after locking screen
I also had this problem with AMD64 & Nvidia Geforce, but it doesn't actually freeze the system, you just can't get out of the screen lock. I solved it by un-checking the option to show notifications on the lock screen - no problems since then. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/1685141 Title: System freezes after locking screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1685141/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

@jaes I'm not sure how you disabled notifications on the lock screen as I'm unable to find any settings along the lines of what you described on stock 17.04.

[Bug 1685141] Re: System freezes after locking screen
Meanwhile, this bug even occurs without locking the screen. After two weeks and approx. 30 occurrences only on one of my machines, I consider this bug critical. I don't even know, if the screensaver-package is the right package for reporting. Seems to me as a general/deeper problem, because it influences the whole system's stability. Compared to 16.10, version 17.04 is a big step back in puncto stability.

I think I found a workaround. I noticed the traceback I saw in syslog happened a lot before I tried to log back in and I deduced it happened when notification were displayed on my locked screen.

[Bug 1685141] Re: System freezes after locking screen
Same happened to me. For whatever reason both Intel Microcode and nvidia proprietary drivers were not used after upgrade from 16.10. The installation of the nvidia proprietary drivers (alone) didn't solve the problem. But now, after additionally installing microcodes it seems to work.

[Bug 1685141] Re: System freezes after locking screen
Well, ignore what I wrote above. The bug occured to me this morning. I still have the kernel trace in the syslog, but taking a closer look at my logs, it seems it occured earlier and not just when reactivating the screen. Might be related to the displaying of notification by the locked screen.

** Attachment added: "syslog2.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1685141/+attachment/4866358/+files/syslog2.txt ** Description changed: When locking the screen or whenever the screensaver starts automatically, I cannot log in again, but my system completely freezes and I have to restart the computer. In most cases I was able to do the restart by pressing Alt-REISUB, in some cases however I had to do a hard reset. This is a new bug in zesty (Ubuntu 17.04). In the previous version everything worked fine. I tested both the upgrade and a fresh new installation on the same computer. Package is gnome-screensaver version 3.6.1-7ubuntu5. I attach an excerpt from my syslog. Hope this might help to find the bug. I installed zesty on another computer (laptop) as well and there the bug did not appear. So I assume it has something to do with the installed graphics card or graphics driver.
