Dash-to-panel: Unable to start dash-to-panel gnome-shell 3.30.1+29+g38c1ebba6-1

[mikey242]

Hello,

I have been using dash-to-panel on Arch for a few weeks now without issue. This morning I updated gnome shell to 3.30.1+29+g38c1ebba6-1. After a restart I noticed that all the panel content is squeezed into the left corner. I tried uninstalling it and even re-installing without any change. I checked gnome-tweaks and saw that there was an error saying it was unable to load the extension. When I checked the journalctl I noticed these lines:

Oct 10 10:28:58 Arch-PC gnome-shell[2675]: GNOME Shell started at Wed Oct 10 2018 10:28:57 GMT+0200 (CEST)
Oct 10 10:29:35 Arch-PC gnome-shell[2675]: Extension "[email protected]" had error: Error: No signal 'allocate' on object 'Gjs_Panel'

I have also noticed it sometimes says "TypeError: overview is undefined", similar to #464.

I found this thread on the Arch forums from earlier today. Not sure if it's related:
https://bbs.archlinux.org/viewtopic.php?id=241108

Edit: Just reverted back to gnome-shell-3.30.1-1 and everything works fine now.

Confirmed, I have the same problem.

@mikey242

just out of curiosity, do I need to do something special for downgrading to last version of gnome-shell? After running "pacman -U gnome-shell-extensions-3.30.1-1-any.pkg.tar.xz" I get the following in the terminal, but the actual version stays the updated one, i.e. nothing really changes:

(2/2) Arming ConditionNeedsUpdate...

I even tried to downgrade to a version 3.30.0, and still the installed version remains 3.30.1+29

Am I doing something wrong? Restarting the shell or computer does not change anything...

That's the command I ran, the only difference is that I specified the location (in cache) of the package to install:

sudo pacman -U /var/cache/pacman/pkg/gnome-shell-3.30.1-1-x86_64.pkg.tar.xz

I didn't have to do that bcs I was already in that directory when I ran the command... But whatever I do, when I look at installed packages in pamac (I use Antergos, so that's my default GUI package installer) it is still the last version to which I updated yesterday. It doesn't downgrade anything. Weird. This usually works for me with no issues... And Pamac (as far as I know) has no ability for downgrading.

Thanks, seems like gnome-shell deprecated Shell.GenericContainer in 3.30.1. We'll have to adjust, I'm looking into it.

[craigacgomez]

Maybe this commit https://gitlab.gnome.org/GNOME/gnome-shell/commit/ad134ab66ee1c45092e4295bb0c17b9726eba601 which replaces Shell.GenericContainer with St.Widget (in boxpointer) will be a useful reference.

[work-chausat]

i have the same problem too!!!!!!!!!!!!!!!!!!!!!!!!!!

[work-chausat]

I have the same problem too!!!!!!!!!!!!!!!!!!!!!!!!!!

[VxMxPx]

Same here. For anyone who has this problem, downgrade gnome shell for now, using command mikey242 provided:

sudo pacman -U /var/cache/pacman/pkg/gnome-shell-3.30.1-1-x86_64.pkg.tar.xz

[robvelor]

@charlesg99 Thanks for looking into it, hopefully it is a quick fix.

[libcg]

To be fair, it looks like arch should start packaging from the gnome-3-30 branch instead of master. I think Shell.GenericContainer deprecation is targeted for 3.32, even though most of the associated fixes will land in 3.30.

As discussed on IRC, I've adapted this merge request to be stable-friendly, by removing the commit shell: Remove ShellGenericContainer. This commit will be introduced by a separate merge request that will be merged only on master.

[Bruce-YC]

Same issue here... downgrading gnome-shell worked well

[charlesg99]

A fix for this issue was added to master. Please let us know if you encounter any problems with it. Thanks!

[zurchpet]

master indeed works on 3.30.1+29+g38c1ebba6-1

Thanks for the fix!

[work-chausat]

the fix works now, thank charlesg99, well done!!

[mikey242]

Great, it's working fine now. Thanks for the quick fix!

[vieruuuu]

I updated gnome-shell and everything works for now

[charlesg99]

I realized that the icon paddings were a bit off after the fix. The styling was adjusted on master. Thanks for the feedback!

[work-chausat]

after using "Adjust icon paddings following Shell.GenericContainer deprecation", it becomes too ugly, the icons are not centered!!!

[charlesg99]

@work-chausat What do you mean not centered? What gnome-shell version are you on? What dash-to-panel size settings are you using?

ubuntu 18.04:

[work-chausat]

@work-chausat What do you mean not centered? What gnome-shell version are you on? What dash-to-panel size settings are you using?

ubuntu 18.04:

use panel size 39, margin 4, padding 4 to try! Then see the icon and its background

[charlesg99]

[work-chausat]

As follows, 4b639ec is ok!

As follows, 55da368 is not ok!

[work-chausat]

4b639ec is ok, 55da368 is not ok, 55da368 is too ugly, the icons in 55da368 are not centered!!! The version of my gnome-shell is 3.30.1

[charlesg99]

What gnome-shell version are you on? What distro?

[work-chausat]

What gnome-shell version are you on? What distro?

3.30.1+29+g38c1ebba6-1, archlinux

[DuckThom]

I'm experiencing the same issue with the non-centered icons. I'm on the same version and OS as @work-chausat
The icons seem to be offset a bit too far to the right.

[charlesg99]

Yeah I can reproduce, the new baseicon allocation introduced in 3.30.1+29+g38c1ebba6-1 doesn't allow non squared layout. I added a fix to add the side paddings back, without distorting the baseicon.

[work-chausat]

b8ab43f is much better, but it is still a little to the right, 1 or 2px perhaps.

[DuckThom]

It's indeed much better now, however there seems to be a vertical line when there are 2 windows open of the same app

[charlesg99]

Ok please try again, I believe that, this time, I tested everything :)

[DuckThom]

Yep, looks good now :smile:
