Bug Description

Binary package hint: gnome-panel

After booting with latest natty updates noticed this error message in .xsession-errors.

Also, I had set up a couple panel bars with window lists on them (old school style). This is running classic desktop (no effects) fwiw.

Unable to find a synaptics device.

Also, three dialogs had popped up asking me if I wanted to delete the window list from my configuration. I declined.

I've reported bug 730581 which (even more so now that I have examined and posted my .xsession-errors file) I suspect may be a duplicate of this bug. What do you think?

As explained in bug 730581, additional information has arisen which indicates to me that it's a duplicate of this bug, so I've marked it as such. Perhaps it contains useful information.

Bug 730581 occurred on an installed Natty system, rather than the live CD. So it appears that this bug is not limited to live systems.

This bug affects me nearly every time I boot into Ubuntu Classic with no effects. And I'm using a Natty amd64 system.

I have the same issue, but it also happens sometimes for the clock applet and the system tray applet (which causes new problems because programs with system tray icons report that they could not add their icon to the tray).

I have similar problem after upgrade to 11.04. Only wallpaper is visible nothing more. I cannot even run ALT+F2. When I tried to run Ubuntu-Classic, then it is the same problem.

This issue has been reported independently to gnome bugzilla.

https://bugzilla.gnome.org/show_bug.cgi?id=637219

There's even a comment that has identified it as a race condition and has offered a simplistic workaround to prove that.

I experience this issue almost every time I log in on natty with gnome classic.

A workaround is to restart gnome-panel after the error occurred. Just enter "pkill gnome-panel" into console.

Confirmed this issue exists in 11.10 since "a" november update.

Confirmed, "pkill gnome-panel" workaround works in 11.10.

Seems to be resolved via "a" december update in 11.10, I have gnome-panel 1:3.2.0-0ubuntu1 now.

go to your home folder

press cntl + h

then your home folder will display hidden files

check whether any of the folders is locked

right click on the folder then click "properties". In that Click "permissions".

In owner, change folder access to "create and delete files."

And then click "Apply Permissions to Enclosed files"

If you cannot see any locked folders then select all folders and do the above

I decided to go back to 10.04.3, 11.10 has too many system freezes/bugs and slowness and other user-level inconveniences.

In 10.04.3 this and many other issues does not exist, and everything is much faster in general, booting, starting applications etc, compared to 11.x
