"no system tray detected on this system." Appears starting Gnome and Cinnamon in Oneiric 11.10; starting with Gnome Classic and Unity no problem at all. How to solve?

I had this error on every boot on ubuntu 18.04 Bionic Beaver after installing the drivers for my HP printer.

I just deleted the file

/etc/xdg/autostart/hplip-systray.desktop

to get rid of the problem.

    If you don't want to remove it, changing its extension also works, for example extension old: /etc/xdg/autostart/hplip-systray.desktop.old – alditis Jun 29 '20 at 13:28

In your start up programs there is a line regarding starting hplip. Change ...

sh -c "sleep 15; exec hp-systray"

to

sh -c "sleep 45; exec hp-systray"

and the problem is gone.

hplip is expecting a system tray and that got removed (and was changed into notification area). All this does is postpone startup of hp-systray so if your system is slow to respond this notice might come back and bite you again.

Found it here on Bugzilla (has a fix released on 2011.11.25 (...)). Besides the bug I found the following sources: Linuxquestions, Ubuntuforums

  • Thank ouy Rinzwind for your answer. BUT: where can I find that line in my Start-up programs "sh -c" etc.? I tried Grub, .hplip and the systray-itself,start-up programs. – tonwillems.pc Feb 08 '12 at 14:12
  • Not a problem @tonwillems.pc :) if the answer is what you needed do not forget to accept it ;) – Rinzwind Feb 08 '12 at 14:13

  • Excellent! @tonwillems.pc glad you got it sorted O – Rinzwind Feb 14 '12 at 15:15
  • @tonwillems.pc In my hplip there's only "hp-systray -x" – JK andy-drew Dec 01 '17 at 21:06
  • Which file in the startup are we supposed to change? Please provide a path. Got this error when trying to install hplip-3.18.9.run – lovedrinking Oct 28 '18 at 02:51

    @lovedrinking In Debian 8 (Jessie), you can find the command of interest in the /etc/xdg/autostart/hplip-systray.desktop file, where I changed the line of interest from Exec=hp-systray -x to Exec=/bin/sleep 15 && hp-systray -x. End of problem, for me...dunno if this helps for Ubuntu... – Digger Sep 26 '20 at 19:03

  1. Go to start up applications using Launcher
  2. Uncheck HP system tray service

  • To bad we can't make it work, though. I was able to restart it and I see the icon, but the icon is not reacting to my clicks... – Alexis Wilke Apr 05 '20 at 18:04

    For me this is the best solution. Even with a 90 second delay in /etc/xdg/autostart/hplip-systray.desktop the problem was not solved for Ubuntu 20.10. – H2ONaCl Mar 16 '21 at 05:50
  • Not too sure what happens, but I can now access the menu, only it takes some time to wake up. I do not know how much time. But just after I restarted, the icon doesn't respond for a while. – Alexis Wilke Dec 12 '21 at 00:20

sudo apt-get install hplip hplip-gui

will install a newer release of hplip that might fix the issue.

note: you can navigate to /etc/xdg/autostart

then look for the file: hplip-systray.desktop

In the meantime open a terminal and login as root.

write in terminal:

sudo rm  hplip-systray.desktop

then drag hplip-systray.desktop file and drop it in terminal and hit enter. That's all.

note: or simply login as root in terminal and write: 

sudo rm  /etc/xdg/autostart/hplip-systray.desktop

and hit enter

  • I navigated to /etc/xdg/autostart/ and then ran sudo rm -R hplip-systray.desktop which was by far simpler. No error then appeared on reboot. – graham Mar 26 '19 at 19:19

Run this command:

sudo apt-get install hplip hplip-gui

When prompted, choose Yes to install new version/release. After installation, reboot your PC/laptop, and you will see HP GUI in your upper right next to your wifi connection icon.

This was tested on Ubuntu 19.04

I had been using MenuLibre (aka 'Menu Editor') to clean up my xdg applications, as there were a bunch of them in bad state after years of hacking.

(BTW, the Menu bar | Menu Editor | Parsing Error Log command produces a nice list of application desktops that are broken in some way or have other errors.)

So I had edited ~/.local/shared/applications/cinnamon.desktop just to simply give it a better comment, i.e. that if run it would restart cinnamon. (As I can now see, it also starts cinnamon, like initially.)

But MenuLibre had revised it further, and without telling me, and this had broken my ability for Cinnamon's panel and menu to start up. The background was black, and I could only operate on GUI tool, the most recent one, and there were no close buttons on anything. ..

(But, note I could right click on the screen and get a terminal and also I could use Ctl-Alt-F1 to open a tty.)

To find the solution to what had broken I had to restore ~/.local/shared/applications. Then little at a time with divide and conquer I located the file that caused the issue, that is after a whole bunch of painful reboots to test it.

tl;dr: SOLUTION: Restoring this file fixed things: 

~/.local/shared/applications/cinnamon.desktop
