I have to close & restart Plank at each computer start

Hi !
I have a problem with Plank on Manjaro only (I also use Debian + Xfce, Xubuntu & MXLinux with about the same settings and… Plank and… no problem on them).

Each time I start my Manjaro, Plank autostarts and… opened software don’t show (if I click on an app, it opens, but then doesn’t appear as open and cannot be selected).
I then have to close Plank and restart and then it’s functional.
This happened already on 3 different installs of mine with various kernels.
Sometimes, on a new install, Plank will behave normally during a couple of weeks and ultimately behave like I just described.
Thus deleting the profile is not sufficient : it is not the origin of the problem.

(There it’s functional, even if errors seem to show)

I don’t know where to eventually look for a log.

I tired to delay autostart : then it doesn’t start at all…

Any hint or advice ?
Am I the only one to experience this ?

The only thing missing from your excellent debugging is: How did you install Plank?

If the answer is:

pamac install plank

Open a bug wit the developers, because Manjaro has the very latest build and you might have run into a bug. If not, please elaborate.

:+1:

Since it runs automatically, there are a couple of approaches to see if you can debug it yourself using delays. One method, if your desktop supports it is to set the delay of the applications which run at session login. The other is to use sh sleep for forcing a delay. Example:

sh -c 'sleep 10 && plank'

The reason I recommend to enclose with sh -c is because I’ve had some weirdness come from adding command sequences directly. Also handy to know for certain applications which expect you to be at a specific directory prior to execution for use with custom launchers.

See how that goes and hollar back.

Quick edit: I wouldn’t imagine it to be the case for you currently but some desktops have another set of startup applications considered as “Essential” which reload on crash if possible. In my specific instance using MATE I can set Dock preference with gsettings as shown.

gsettings set org.mate.session.required-components dock 'plank'

Obviously this will vary between desktops, use your best judgment and consult documentation regarding session configuration.

Hi, thank you for caring !

@Fabby : this is the official repository package, indeed.

 ~]$ plank -V
0.11.89

It’s the same version on my Xubuntu and 0.11.4 on Debian. The only problem appears on the Manjaro (I have about 50 outside installs with Plank).

@Hebgbs : I tried your first command, seems better than my non working :

plank -p 10

as it starts and seems to behave properly.

This is nevertheless a turnaround, I’d be curious to grasp why I have this very problem only on MAnjaro.

I’ll introduce a launchpad ticket, but as I see the activity, it’ll not be quickly taken into account ! ^^

Try building it from AUR and see if the sh command is even necessary then? I know I have some weird issues myself that differ from a live session I’ve yet to solve, but using the latest version from GitHub is a good way to resolve problems occasionally.

killall plank
sudo pacman -R plank
pamac build plank-git

Adjust your autostart so it just runs Plank (without sh and sleep) and log out. If it works once you sign in, great. If not…

pamac remove plank-git
sudo pacman -S plank

Well, I just checked what it would do and wonder if I really need to install gnome-common on my Xfce ?
