Bug Description

I found a number of users with this same bug on Stack Exchange: http://elementaryos.stackexchange.com/questions/7680/wingpanel-not-responding-loki (unlike the original poster, I did not install Dropbox—only major install was the Google Chrome repo and app)

I returned from system sleep to find the menu bar gone. When I Ctrl+Alt+Del, I get a notification that wingpanel is not responding, but no feedback if I opt for force quitting it. New Loki install, Intel integrated graphics on Gigabyte GA-H110M-A motherboard.

"sudo killall wingpanel" has no immediate change, but shows a small, white "wiping"-style movement in the top right, like when a notification closes. Sometimes the menu bar restores, but none of the icons or Applications menu respond. (Once I saw the bottom of the message bubble-style popout come out of "Applications", with the triangle part of the bubble pointing to Applications, but all but the bottom white margin of the bubble off the top of the screen. Eventually, I get another notice about how wingpanel is not responding. Force quitting starts the same process anew. I'm unable to get a working menu bar even after rebooting.

Update: The menu bar does become functional again, but only after a notification that I am connected to wired ethernet (even though I haven't touched the computer or installed anything to prompt the change). It quickly becomes unresponsive again.

Hey, unfortunatly I can't reproduce this.
If you or somebody have time to test some stuff it would be great.
It would be helpful to know if it is a indicator or wingpanel.
You could remove all indicators with:
sudo apt-get remove wingpanel-indicator-ayatana wingpanel-indicator-session wingpanel-indicator-bluetooth wingpanel-indicator-network wingpanel-indicator-sound wingpanel-indicator-datetime wingpanel-indicator-notifications wingpanel-indicator-keyboard wingpanel-indicator-power

and test if it is better. If yes add one indicator at a time and figure out which is it.

To get all back just run:
sudo apt-get install wingpanel-indicator-ayatana wingpanel-indicator-session wingpanel-indicator-bluetooth wingpanel-indicator-network wingpanel-indicator-sound wingpanel-indicator-datetime wingpanel-indicator-notifications wingpanel-indicator-keyboard wingpanel-indicator-power

affects: elementaryos → wingpanel

✓ wingpanel-indicator-datetime
✓ wingpanel-indicator-notifications
✓ wingpanel-indicator-keyboard
✗ wingpanel-indicator-power

Looks like it's wingpanel-indicator-power. It crashes wingpanel each time I install it, no matter what else is installed. Once I uninstall it and restart wingpanel, it appears to work fine.

Same here, without wingpanel-indicator-power everything works. After installing it the panel does not start correctly.

Thank you wolf. This is really helpful to near it down to the right indicator.

I can confirm wing panel bug. But in my case it is 'wingpanel-indicator-session' package which causes the crash. With rest of the package all works fine. I am happy to report further logs if you guys guide me.

I just noticed on a fresh Loki installation that this bug only affects me if I use an external monitor. Without it I can reinstall and use `wingpanel-indicator-power` without any problems.
I'm running on a Dell XPS 13, but had the same problem on a Samsung Series 9 device.

I can confirm that the wingpanel "unfreezes" as soon as I unplug my Logitech receiver. It seems to be the cause of the problem in my case (I use the receiver only while connected to an external screen and have used it on both my Samsung series 9 and Dell XPS 13)

I can confirm that this issue may be related to solaar or its dependencies. Furthermore, the issue did not manifest up until I connected a K750 keyboard. The two mice connected earlier (M570 and M720) did not cause any issues that I was aware of.

It's still happening for me using elementary OS 0.4.1 Loki (updated today) and Logitech K750 keyboard and Dell XPS 13.

Can I help debugging the problem?
