No system tray detected by hp-systray

[Sushenjit Bandyopadhyay]

I have hp-systray -x as one of the startup applications when I login. This app exits with the following error:

HPLIP Status service
No system tray detected on this system.
Unable to start, exiting.

Once logged in, if I start hp-systray -x from the terminal it works fine. This started happening after updating gnome-shell-extension-appindicator from version 33-1 to version 33.1-0ubuntu0.20.04.1.

Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

Same as above...

The problem seems to affect Zoom indicator icon as well.

If Zoom is set to start automatically at logon, the Zoom indicator icon does not show in the appindicator even though Zoom starts. If I quit zoom and start it again manually the zoom icon appears normally in the appindicator.

This bug ("No system tray detected on this system") also occured years ago and a workaround was to change ~/hplip-systray.desktop to increase the "sleep" time:

Exec=sh -c "sleep 60; exec hp-systray"

but this does not work anymore after the latest Ubuntu update.

Affects OwnCloud and NextCloud as well.

Icon tray works for Ulauncher and Duplicati but not for Hplip - Thanks.

Also affects CopyQ, with two different behaviours:

1. CopyQ starts without system tray (app icon visible in the sidebar)
2. CopyQ starts - if I try to start it again it gives the message "Warning: Il server CopyQ è già in esecuzione.", and "ps -eF | grep copyq" shows the copy processes - but it's not visible in the tray.

To bring CopyQ back to the tray, i have to do:

- "killall copyq" from the terminal
- Start CopyQ from the activities view (Super key + search "CopyQ")

I also tried to change the autostart command adding a sleep: "sleep 10 && /usr/bin/copyq", without luck, the icon is never shown in the system tray.

In addition to coming up on startup, I've been getting this error occasionally.

This also affects symless/synergy v1:
  Receive error message 'No system tray detected on this system'
  Synergy is started without systray icon visible after Ok'ing the error message

I have the same hplip-systray error as listed in description.

This also affects seadrive and seafile clients. I also see this on hp-systray and nextcloud. Enpass is not affected.

I have found a workaround by adding a sleep period of 5s in the startup application command line for my synergy and hplip-systray on ubuntu 20.04:

 sh -c "sleep 5 ; exec /usr/bin/synergy"
 sh -c "sleep 5 ; exec hp-systray -x"

I am also affected. Ubuntu 20.4 con hplip.

I am also affected with HPLIP and Nextcloud. Icon's do not display as there is no System Tray. Killing the apps and restarting them works, so the "delay" is likely the issue again.

I am also affected.

It also seems to affect the Mathpix app (https://snapcraft.io/mathpix-snipping-tool), at least for me it stopped working together with HP System Tray Service and Nextcloud.

I'm affected, using Ubuntu 20.04.2. Happens to CopyQ and Flameshot if set on autostart.

Workaround as given by reporter, is WORKING!:

sudo apt install gnome-shell-extension-appindicator=33-1
sudo apt-mark hold gnome-shell-extension-appindicator

Thank you ~s-bandyo1 ! :)

[Paolo Pustorino (stickgrinder)]

I'm also affected.
Sleep workaround works, but I choose to downgrade to the working version.

[Sønke Lorenzen (solorenzen)]

The update to gnome-shell-extension-appindicator 35-1 on hirsute today fixed this for me on hirsute.

At least I got the applet loading without problems three restarts in a row, and recently it failed on every restart on the previous version.

[rajesh kumar (rajesh-chaurasiya)]

this bug also affects me. neither of the suggested solutions work. (neither setting sleep nor downgrading gnome-shell-appindicator).

any new suggestions are welcomed.

[Götz Waschk (goetz-waschk)]

@rajesh, have you updated gnome-shell-appindicator to the official update released for focal?
