Ubuntu: How to Recover from a Frozen, Hanging Main Applications Menu Bar CodeUnit 12 DEC 2011

Sometimes the the gnome-panel process falls over, resulting in hanging or frozen menu bar or context menu. Particularly annoying is when the main application menu bar panel hangs, resulting in a pretty unusable system.

Luckily there is actually quite a simple fix for this in order to force a restart of the gnome-panel system.

First, open a terminal window by pressing Ctrl+Alt+t

Once up, run:

pkill gnome-panel

That’s it. Watch in amazement as the top and bottom menu panels disappear, and then after a brief moment, reappear as the system automatically restarts the shutdown gnome-panel process.

Nifty.

How to Restore the Main Application Menu Bar in Ubuntu CodeUnit 05 DEC 2011

Annoyingly, I somehow managed to get the main application menu bar at the top of my classic 11.04 Ubuntu desktop to disappear. Be it from a corrupt panel entry or an accidental deletion, the fact of the matter was that the entire top menu bar panel had disappeared, rendering the workstation just about useless – and simply rebooting the machine wasn’t bringing it back.

Without the menu items, basic GUI-driven tasks become pretty impossible, so the easiest way to recover from this situation is simply to restore the system panels back to their default state. To do this, launch a terminal by pressing Ctrl+Alt+t.

Once open, enter the following lines to delete the current panel setup and force a restart of the gnome-panel service:

gconftool --recursive-unset /apps/panel
rm -rf ~/.gconf/apps/panel
pkill gnome-panel

Your top and bottom panels should now reappear, albeit in their default install state.

Doesn’t matter, at least I can use my machine again! :)
