Super key / Alt+F2 not working in Ubuntu 11.10

Nabil — Thu, 20 Oct 2011 12:19:23 +0000

This happened to me in Ubuntu 11.10 (Oneiric Ocelot) when I was playing with some Compiz settings. To have your shortcuts back, go to the CompizConfig Settings Manager, to do that bring up a terminal window with the shortcut ctrl+alt+t the type ccsm:

imame@meta:~$ ccsm

If you are using Unity open Desktop > Ubuntu Unity Plugin but if you are using Gnome shell choose General > Gnome Compatibily – anyways, choose whichever is already checked, one the next window check that the shortcuts are enabled and configured correctly

Classical Gnome in Ubuntu 11.10 (Oneiric Ocelot)

Install necessary packages

In order to have Gnome classical appearance on Ubuntu 11.10 you need to install gnome-shell and gnome-panel, a following reboot -from my experience – is preferable.

imame@meta:~$ sudo apt-get install gnome-shell gnome-panel
imame@meta:~$ # blabla while packages are being installed
imame@meta:~$ sudo reboot

Log in using Gnome Classical

Before opening your session, clear the gear next to your name and choose Gnome Classical.

Tweak with Gnome Tweak Tool

You can personalize you desktop with the Gnome Tweak Tool:

imame@meta:~$ sudo apt-get install gnome-tweak-tool

The launcher is located here: Applications > Others > Advanced Settings

Where is “Add to panel” and others?

Now in order to have the penel related options a simple right click won’t work, you need to Alt+ right click

How to upgrade Ubuntu from 8.10 to 9.04 using the command line and the Internet?

You can upgrade your linux system using the package manager APT which is available on debian based distributions:

First we have to update all the packages installed:

$ sudo apt-get update $ sudo apt-get upgrade

Now we make sure that we have the update-manager-core package installed with:

sudo apt-get install update-manager-core

Then we start the upgrade

sudo do-release-upgrade

How to read .chm files in Ubuntu

This tutorial assumes that you are a sudoer running Gnome

What is .chm

Wikipedia says:

Microsoft Compiled HTML Help is a proprietary format for online help files, developed by Microsoft and first released in 1997 as a successor to the Microsoft WinHelp format. It was first introduced with the release of Windows 98, and is still supported and distributed through Windows XP and Vista platforms.

Install Xchm

The default installation of Ubuntu doesn’t include any reader for CHM help files, but you can add one easily.

I personally prefer Xchm which is lightweight and very user friendly, here is the command to install it:

user@computer:~$ sudo apt-get install xchm

You may be asked to enter your password.

Set default application

Now you need to associate files with the .chm extension with Xchm, so next time when you (double)click a CHM help file, it will automatically open it in Xchm:

Right-click on any file with the .chm extension then click “Properties”
Select the “Open With” tab and click “+ Add”
Choose xchm and click “Add
(!) Hint: if you can’t find xchm easily, type it on your keyboard and it will be highlighted

Demo

Here’s a screenshot of what Xchm looks like
