It happened again [in gnome/xorg] while filing this report via abrt - when I clicked on this bugzilla url - that abrt created.

Atleast gnome/xorg restarts gnome-shell without logging me out - like gnome/wayland.

If I'm the only one with this problem - wondering if some local setup is triggering this issue for me..

Comment 19 Berend De Schouwer 2017-10-06 05:16:48 UTC
I've had this a couple of times now.

Twice when I went to view notifications in the clock, possibly just as another one popped up.

At least a few more times when I didn't.

gnome/wayland, so it logs me out multiple times per day.

Comment 22 Berend De Schouwer 2017-10-06 11:22:53 UTC
I have now had this while away from my desk, which points to:
- notifications
- time

At the same time when I logged in I had "NaN new messages" notification, which also points to notifications being broken.

Further, I've had it crash at least three times by clicking on the clock to show notifications.

I've now switched notification popups off in settings, hoping it will help.

Comment 24 Berend De Schouwer 2017-10-06 13:51:14 UTC
So gnome-shell also crashes with all notifications off.

With all notifications off, though, I still get some notifications, for example: selinux/AVC notifications in the clock/calendar.  This might be because sealert is a tray icon application.

Comment 26 Berend De Schouwer 2017-10-09 07:34:13 UTC
I can fairly reliably crash gnome-shell doing:

1. suspend & unsuspend
2. immediately run: notify-send --expire-time=1000 Hello World

It's not necessary to be a notification.  Both portal logins (browsers?) and shell context menus have triggered the crash.

It's not necessary to suspend & unsuspend, but that does greatly increase the repeatability.

Two days ago, I restored gnome settings to it's Defaults (remove ~/.gnome* and ~/.config/gconf directories), and I had no crash since that.

I've removed the above config files - and still got a crash

Similar problem has been detected:

very specifically a notification (gnome-terminal completed a process while gnome-terminal wasn't focused.)

That notification does not appear in the notification list (the calendar list, it still has two other prior notifications.)

I've since tried disabling gnome-shell extensions and various settings, and it still happens.

On Wayland it means a logout every few hours.  On Xorg it's not as severe.

It looks the same to me.

Recently a similar (but not exact) bug got fixed that had to do with *closing* maximised windows, so there are multiple bugs.  That was fixed by upgrading mutter and mozillajs, IIRC.

I recommend running under Xorg and not Wayland until this is resolved, so that you don't lose data every few hours.

It will also allow for more abrt core dump uploads.

If you don't need notifications, turning them all off will also reduce -- but not prevent -- crashes.

Just in case your comments weren't strictly for his bug. I'm using xorg at the moment based on 'loginctl show-session <id> -p Type'

This bug never reached Fedora 27 as far as I know, the 3.26.1 release reached us after this bug was fixed. Arch people was hit really hard by it because they Arch decided to jump to it.

I can't stand running Xorg right now after running Wayland stable for 3 consequent releases! :)

This confirms my correlation in my bug, but it's one of the reasons to trigger the crash.

However, I disabled a lot of extensions (the only extension I have enabled right now is EasyScreenCast) and autostart apps, and things got more stable right now.

This did reach F27Beta.  #1476603.  It was fixed almost immediately.

I prefer Wayland, but I can't afford losing data every few hours.  With all extensions off it's about once a day, usually very soon after login or suspend.

The decision to classify this bug as a RejectedBlocker was made as it does not affect every install, and neither a reliable reproducer nor a clear cause analysis have been found yet.

Is comment #26 not reliable enough for a reproducer?

If it's not every install, what more information do you need to track it down?

Comment 72 Jonathan Haas 2017-11-07 08:08:58 UTC
I can not reproduce with comment #26. What do you mean by immediately? Even after disabling the screen lock after suspend and just hitting enter to start the command as fast as possible, I can't get it to crash. It just shows the notification.

> Is comment #26 not reliable enough for a reproducer?

No crash here with "systemctl suspend && notify-send --expire-time=1000 Hello World". Even when I disable screen locking.

Comment 74 Berend De Schouwer 2017-11-07 09:42:17 UTC
I still go through unlock, focus terminal, etc.  There's no rush.

I suspect it is related to load or I/O, so it has to be within a few seconds (not milliseconds) of unlock before the machine settles down.


So I suspect we're chasing a hardware or configuration problem.


So, here goes:

- Video: (I don't know which one is actually in use, no games are running)
  - Intel HD 5500
  - AMD Radeon M255
- Display:
  - local panel
  - hdmi external
  - everything @ 1920x1080
- Drivers:
  - i915
  - amdgpu
(I get both amdgpu and i915 warnings in dmesg, not necessarily at the same time as this bug.)
- Protocol:
  - X11
  - Wayland

- gnome-shell
  - tried without extensions
  - multiple workspaces

- filesystem (got mentioned in one of the other bugs, so I'll try and be complete)
  - ext4 on luks on lvm (or is that lvm on luks?)


How do I get a "blank" / "new user" gnome-shell configuration?  How do I clear out F24/25/26 cruft?  (I don't want to throw /home away, though...)

Comment 75 Anass Ahmed 2017-11-07 10:27:16 UTC
The correlation was strong with notifications (also it happened with other events) when I filed my bug 1506706.

I disabled all GNOME Shell extensions and the experience became more stable since.

My machine only crashed twice after that when I was trying to record using EasyScreenCast extension (which sends a notification BTW) on a multi-head setup upon trying to select the secondary monitor as the selected monitor for recording.

I'm gonna re-enable my extensions again now, and find a proper reliable re-producer.

I'm using a very "standard" laptop with a very "standard" installation: Just Intel CPU/GPU, no NVIDIA or AMD, using non-encrypted ext4 for both / and /home, most of the time on a single screen, all under Wayland.

Comment 77 Anass Ahmed 2017-11-07 13:47:54 UTC
We're back with them crashes again after re-enabling extensions. I'm trying to figure out a producer, but I'm suspecting TopIconsPlus is a prime candidate, though the crashes happened without it before.

Comment 78 Łukasz Faber 2017-11-07 13:54:37 UTC
I do not use TopIconsPlus and also have these crashes.

Currently, with only the following extensions enabled, Gnome is quite stable:
- Do not disturb button
- Kstatusnotifieritem/appindicator support
- Topicons (not Plus)
- User themes

I cannot pinpoint the exact extension, but I had much more crashes with the following additional extensions enabled:
- Openweather
- Places status indicator
- Pomodoro
- Recent items
- Removable drive menu

Most of them were installed from Fedora repos, not from extensions.gnome.org.

> but I'm suspecting TopIconsPlus is a prime candidate

I don't think so. I've used TopIcons Plus (and Openweather) for some time now without any issues.

However I've just installed 
- Places status indicator
- Pomodoro
- Recent items
- Removable drive menu

as they were mentioned in comment #78 and the shell almost immediately crashed. It was however reported as Bug 1489554 and not this one. These are all probably related however

Comment 81 Nathanael Noblet 2017-11-07 16:43:16 UTC
I don't know if this is related to notifications. I've had more crashes unrelated to notifications than anything else. Unless the crash is happening because GNOME is trying to display a notification. I don't have anything but the stock extensions that would come with a default install.

I get crashes while browsing websites. I've had crashes switching windows with mouse or alt-tab. I've had crashes while coding via PHPStorm... To me there is no consistency in the crash whatsoever. Also I've checked via loginctl and I'm using x11.

Comment 82 Anass Ahmed 2017-11-07 17:39:12 UTC
I've got more than a bunch of crashes of the same error when I tried to unlock the device after enabling this list of extensions (most of them are from GNOME extensions website):
- TopIcons Plus.
- Text Translator.
- Caffeine.
- Dash to Dock.
- Impatience.
- EasyScreenCast.
- Sound Input & Output Device Chooser.
- Media Player Indicator.
- Status Area Horizontal Spacing.

From Repositories:
- GPaste.
- Pomodoro.

It's literally something with GNOME extensions, I've just crashed GNOME while typing the above list as I found an update for an extension in GNOME Tweaks and I clicked "Update", then it crashed!!

Comment 83 Berend De Schouwer 2017-11-08 12:26:51 UTC
I've enabled and disabled extensions, and for me:

1. enable TopIconsPlus
2. enable Pomodoro
3. suspend
4. notify-send
5. ... crash

Disabling either of TopIconsPlus or Pomodoro stops the crashes.  It's not necessary to disable both.  Are they competing for a resource?  They are both on the top-right corner.

I'll have to run it for longer to confirm that this isn't a statistical fluke.  I do plan to do so.


Note: Pomodoro depends on a helper app /usr/bin/gnome-pomodoro that doesn't stop when you disable the extensions.  You may need to logout/login.

I started to suspect that it happens to any extension that adds its icon to the GNOME Shell top panel.

Comment 87 Nathanael Noblet 2017-11-09 17:03:54 UTC
I realized I had pomodoro installed so removed it on the 7th. I can't recall a crash since then. I'll pay more attention.

Comment 88 Jonathan Haas 2017-11-09 17:13:50 UTC
(In reply to Berend De Schouwer from comment #84)
> It also crashes with only pomodoro.

Definitely sounds like related to pomodoro then. As I wrote before, with topicons (plus) alone or other extensions in the top right corner (like clipboard indicator), gnome-shell is completely stable.

A lot of the people who reproduced chrashes here recently had pomodoro installed.

The question of course is why can an extension bring down the whole gnome shell? I thought they run in some sort of JavaScript sandbox?

Comment 89 IanB 2017-11-09 20:50:09 UTC
I've had crashes with pomodoro but not topicons, and topicons but not pomodoro. Since disabling both of these, my system has not crashed. I do have other extensions running however, e.g. system-monitor

Comment 90 Adam Williamson 2017-11-09 21:59:08 UTC
"The question of course is why can an extension bring down the whole gnome shell? I thought they run in some sort of JavaScript sandbox?"

No, there isn't a 'sandbox' (AFAIK). Extensions can hook into the shell in all kinds of ways. A large chunk of the Shell itself is written in Javascript.

Comment 91 Berend De Schouwer 2017-11-10 06:05:16 UTC
I've just had one gnome-shell segfault when pomodoro was definitely not running.

Running:
- topiconsplus
- freon (installed specifically to have another extension that eats panel space)
- openweather

I've enabled all extensions (including TopIcons Plus) and disabled Pomodoro. Let's see what happens next?!

"Should the component change?"

Well, I don't think we have the pomodoro extension packaged. But it would definitely be a good idea to report this to the upstream tracker for the pomodoro extension, assuming it has one and this has not already been reported.

I disabled pomodoro awhile ago. It is much more stable. However I think I had one crash while pomodoro was uninstalled. Better than one or two a day. I should also point out I had pomodoro installed but wasn't using it.

Looks like disabling most extensions made it stable. I'm trying to enable them one by one to see if I can isolate this reliably. So far Dash to Dock seems like one of the culprits.

Comment 128 Ankur Sinha (FranciscoD) 2017-11-22 11:41:48 UTC
It seems to be related to notifications rather than a particular extension. I get crashes from the mpdris extension too, for example. It could be limited to notifications generated by extensions, but I haven't been able to check that bit reliably yet.

Using the DND extension to disable notification seems to prevent crashes, but since the crashes do not happen each time anyway, I can't yet be certain.

Comment 129 Berend De Schouwer 2017-11-22 12:09:21 UTC
Mat Booth has kindly built a later Pomodoro on Bodhi:
https://bodhi.fedoraproject.org/updates/FEDORA-2017-9103272c93 (f26)
https://bodhi.fedoraproject.org/updates/FEDORA-2017-337c3be857 (f27)

Try it out and leave some karma.  Be sure to logout/login since it leaves a process hanging.

If you haven't got Pomodoro installed, try and find out which other extensions cause this.  Note that some extensions need a logout/login.

gnome-shell 3.26 now has mpdris built in (under the calendar/main notification) so you might want to try that instead of an add-on extension.

Comment 145 Ben Cotton 2018-11-27 15:11:05 UTC
This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora  'version' of '27'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 27 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 146 Ben Cotton 2018-11-30 20:26:03 UTC
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
