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! :)

Ubuntu: How to Add Chrome Launcher to Panel CodeUnit 26 DEC 2009

It feels a little stupid to even right a post about this, but seeing as how I was wondering and wasn’t quite sure how to go about it, I thought it prudent just to leave a little note to myself on how to actually do this – never hurts to leave little notes lying around for one’s self you know! ;)

Anyway, the problem at hand lay in the fact that I had now decided to use Google’s Chrome browser as my Ubuntu default internet browser, meaning that I wanted to swap the FireFox icon sitting in the panel at the top of the screen to that of a Chrome one.

Now the Gnome panel acts pretty much like the Windows taskbar over in Microsoft’s product and so I was pleasantly surprised that actually right-clicking on the panel gave me some options to play with – most importantly the option to delete a launcher icon that I had right-clicked on! In other words, FireFox and Help icons now pleasingly gone. :)

But now, how to add the replacement launcher icon to the panel?

Well obviously you can do it the manual way by selecting the “Add to Panel…” menu option that appears when you right-click on the panel, but this hangs off on you knowing the actual path the to executable you wish to launch – and seeing that I’m still quite a newb when it comes to Ubuntu, for the life of me I couldn’t locate the damn launcher command for Chrome on my system!

Thankfully though, I was saved when I sheepishly right-clicked on Chrome’s launcher icon contained in the standard ‘Applications’ menu and spotted the EXTREMELY handy “Add this launcher to panel” context menu option.

Stupid I know, but at least know you know that it can be done – just in case you were wondering about it of course…
