Ubuntu

panel @ top of screen fails to appear after login

Asked by Will Grant

panel @ top [applications, places, system] fail to appear on restart, after I selected the update to replace quit with an icon that controls logout as well as instant messaging.

After download I restarted my computer, and all panels appeared. A window gave me the option to pick the icon to replace quit. I did so. Then I selected ctl/alt/delete, which produced a choice to close the computer or restart or hibernate. I chose close computer. The operating system closed as far as "Ubuntu" on the screen. On my computer using 8.04, the OS never exited completely. It was always necessary for me to push the button to turn off the machine.

I did the same. Waited. Then started the machine again. That's when I observed no panels.

I am able to write this description, because I accessed internet, using the Help Menu.

The solution to my problem/mistake must be simplistic, but I don't have a clue what to do. Thank you.

To reset the panel to defaults, type this in a terminal:
gconftool --recursive-unset /apps/panel && killall gnome-panel

This will give you default vanilla panels. You can then build from there, sounds like something in gconf has gone screwy and giving you bad panels

Well, any *nix system hates hard reset, sooner or later you'll run into e.g. fsck issues.
Next time rather use MagicSysRq instead.

Or try via terminal:
sudo shutdown -h now
http://theos.in/howto/howto-shutdown-reboot-ubuntu-linux-command/

Consider to solve the shutdown issue for good. In case open a new question or report a bug.
(linked confirmed bugs)

e.g. test option acpi=off and at least disable quiet splash via menu.lst.

Thank you again.  I'll try your suggestion when I discover that 10.04 continues to "lock up" at Quit.

Thanks for reading my question.  Thanks for taking the time to reply.

Thanks for reading my question, and for taking the time to answer it.

The problem is solved. Today upon startup, the OS loaded Desk 1. With Desk 1, both top and bottom panels loaded. My screen now looks the same as it did following the restart required to complete the download.

Thanks again. Yippee!

Will,
this is an essential note, your entry post mentioned:
> On my computer using 8.04 ...

then you say:
> I'll try your suggestion when I discover that 10.04 continues to "lock up" at Quit.

Hence, bug reports and links concern 8.04 which is quite different from 10.04.
So, please let me know which Ubuntu you run, in case to remove bug links to avoid confusion.
Please open a terminal (applications -> accessories -> terminal) and post output of:
lsb_release -d

## Please, avoid reply via email, since the already given answer is quoted over and over again, which makes a question unreadable, rather directly reply via web browser. Thanks.

I hope this reply meets your expectation.
I upgraded last evening to 10.04 from 8.04.   10.04 appears to work and to shut down and restart w/o problem.

You request that I reply directly using web browser.  I am uncertain of the procedure to meet your request.
