Switching to next wallpaper deactivates all shell extensions #21

Open paddyesch opened 8 years ago

paddyesch commented 8 years ago

I used the 'next' button to switch to the next wallpaper and all shell extensions were deactivated. However, it doesn't happen every time I click 'next', only sometimes. I'm using Fedora24 (GNOME Shell 3.20.3) and the latest version of randwall from extensions.gnome.org.

Otherwise, I'm very happy with this extension, thank you!

Hi!

Mmmm... I cannot reproduce that behaviour on a fedora 24 with gnome-shell 3.20.3. I know it's difficult but if you could add some logs when that behaviour occurs I will try to check what happens.

zapashcanon commented 8 years ago

I can confirm this: I used to have the same issue. But now, as I let the extension running in the background and don't touch it, I don't experience it anymore. It was on Debian Unstable, probably not with 3.20 at the time, but I'm not sure...

mrEDitor commented 8 years ago

I have this issue too, and the only known to me way to reproduce it ­— change wallpapers really lot of times. But sometimes it appears when background is changing by timer, too.

I don't have any warnings or errors when it happens, just reboot logs of Gnome Shell and extensions. Also it looks like that if I just remove Gio.Settings.set_string(...) code, all is working well (except wallpapers do not change, of course), so I think it might be Gnome Shell bug or some kind of race condition.

rodakorn commented 8 years ago

Ok. For me it's a little difficult to test it with a fedora because I use debian... actually yesterday I asked a friend of mine that uses fedora to check that issue but he couldn't reproduce it. But seeing that some of you confirm this issue and is not an isolated problem I will make a VM to properly test it.

Thanks everyone for the feedback.

mrEDitor commented 8 years ago

Actually, I use Archlinux.

What is about the bug, something like

 settings = new Gio.Settings({schema: 'org.gnome.desktop.background'})
 picture = settings.get_string('picture-uri')
 for (let i = 0; i < 150; i++) settings.set_string('picture-uri', picture)

in Looking Glass will give same result (but will make more damage to Shell instance 'cause runs under lg and forces nearly whole shell to restart).

zapashcanon commented 8 years ago

@rodakorn I was/am on Debian too. IMO it's not specific to Fedora.

rodakorn commented 8 years ago

I don't think it's fedora specific either, but on a debian with gnome-shell 3.14.4 I cannot reproduce this issue (later I will try mrEDitor suggestion) but I thought maybe it has something to do with gnome-shell version because is not the first issue that I receive from people using gnome-shell 3.20... So I'll try with a Fedora that uses a 3.20 gnome-shell version

zapashcanon commented 8 years ago

At the time I was not on 3.14 but 3.16 or 3.18 I'm not sure sorry.

paddyesch commented 8 years ago

Correction: I can reproduce this bug. It just happens really rarely by clicking on the 'next' button.

I recorded the output of this command while the shell crashed:

journalctl /usr/bin/gnome-shell -f -o cat

http://pastebin.com/hc1vjGZg

The crash occurred after line 10 I think. Hope it helps.

I'm afraid I can't reproduce this issue either. I didn't really change anything (other than playing around with unrelated extensions) but continuously switching to the next wallpaper works fine now.

A wild guess: I experienced this bug right after installation several times but maybe a reboot fixed it somehow.

urandom commented 8 years ago

On arch linux (gnome 3.20), I've been having this issue for quite a while now. It's not related to the manual wallpaper switch, but changing the wallpaper itself. I've been noticing that after a while, the extension will crash and take all extensions after it (alpha) with it. I only managed to pinpoint the problem to the actual switching when I caught it crashing while the wallpaper was being switched automatically at some point, and, iirc, the laptop froze for a second or so (I guess a lot of i/o was happening or something).

zapashcanon commented 8 years ago

Indeed, with a little time value for changing the wallpaper it happens again. I though it was when switching the wallpaper manually but it's more like @urandom just said.

So, in a terminal:

gnome-shell --replace &

Then, I switched the wallpaper a lot of time and when the bug appeared, I had this output on my terminal.

Don't know if it helps. @rodakorn

danielquinn commented 8 years ago

Perhaps it's not the plugin at all, but the image randomly selected? Has anyone managed to intentionally reproduce this problem in a reliable way?

zapashcanon commented 8 years ago

@danielquinn: I tried another extension (BackSlide) with the same set of images, I had no problem. The main differences with randwall is that rand wall search for images in a given folder when in BackSlide you have to add images to the list yourself (ie: it won't search for new images in a folder). So I think it comes from randwall. Moreover, you can reproduce this problem just like I said: switching to the next wallpaper many times and it will happen. (That said, I didn't try since my last comment)

Similar problem on Arch Linux 64 bits and GNOME Shell 3.22.2. In my case, sometimes, when I waked up the session after screen goes off, the extensions weren't enabled again but "gsettings get org.gnome.shell enabled-extensions" showed the right value. To "solve it" I had to relogin to gnome session. https://bugs.archlinux.org/task/52490 After disabling this extension, the problem gone.

j-keiter commented 7 years ago

This problem has persisted for last year on 3 different computers from ubuntu gnome 15.04 to 16.04. Love the extension but It always randomly shuts off all other extensions about every 10min to an hour after restarting gnome-shell. I attached a copy of my journalctl just after all my extension suddenly turned off.
journalctl_output.txt Wish I could help fix.

mrEDitor commented 7 years ago

Just a feedback to extension developer and users: noticed no crashes anymore for a long time. I am on Archlinux with Gnome Shell 3.22.3-2 / Gnome Desktop 3.22.2-1 currently. Any more remarks?

simonbcn commented 7 years ago

I'll test but the last reports: https://github.com/rodakorn/randwall/issues/21#issuecomment-273427815 and https://github.com/rodakorn/randwall/issues/21#issuecomment-277303925 are subsequent to the last significant change in the code: https://github.com/rodakorn/randwall/commit/ff4715a5ed78ad5b4bfa4ca6d0204edfa71b19ee

mrEDitor commented 7 years ago

I'm still pretty sure that the bug was in the Gnome Shell itself, not in the extension.

simonbcn commented 7 years ago

@mrEDitor you are wrong. This extension is really buggy. I have installed yesterday and now I can reproduce this issue. The problem now is worst for me:

  1. The desktop hangs several seconds.
  2. All extensions are disabled.
ieugen commented 7 years ago

It deactivates all extensions for me too. Things started happening like this after I installed it. Once I deactivated it, everithing is ok.

Using Debian Stretch with Gnome 3.22 .

It is really buggy.

Vaesper commented 7 years ago

Arch Linux 64 bit with Gnome 3.24 on Wayland... Crashes the shell on both my laptop and desktop (similar setups). More often on desktop where my wallpaper resolutions are bigger.
