How to continue using GNOME2 with Ubuntu or a derived distribution?

Linux Mint is a Ubuntu derivative that is currently continuing with Gnome 2. They also have a project in place to address some of the concerns that Gnome users have with Gnome 3, and are making a more Gnome2y version of it.

Launching gnome-shell-timer in Unity?

You probably just need to add the applet to the panel. I am not running gnome at the moment but it should be something like Right Click on the panel => "Add applet to panel" or "Panel properties" or similar.

Ubuntu 12.04 blank screen after login

"Out of range" error

This is not from your BIOS. This is coming from your monitor. It is a message from your monitor that whatever signal is being sent to it is out of the display range capabilities of the monitor. Most likely it is the resolution of the text-only mode that you would see while the system is loading, especially considering that when you attempt to return to it by bringing up the console, you get that error again.

EDIT Just to be clear, there are two separate issues here. The Out of Range issue isn't related to why Ubuntu doesn't load fully once the GUI is up.

Dragging windows in Ubuntu Unity

Yes, it is intended that you can drag your windows when you invoke your Alt key. I don't have a reasonable answer for why it is like this.

If you are looking to simplify the dragging process, you can drag the windows around without using Alt key by clicking on the title bar and dragging like you normally do.

Is there a WinSplit Revolution style window manager for Ubuntu Unity (11.10)?

The same key combination works in Ubuntu 11.10 using Unity 3D (not sure about Unity 2D). Place focus on the desired window then press and hold CTRL + ALT + any of the numpad keys. You can position the window in any corner or even center of screen. Repeated use of the same number will resize the window while keeping it in the desired screen corner.

Unity Window Manager should be short for Unity.

Ubuntu Geek has a short list of keyboard shortcuts that you might find useful: http://www.ubuntugeek.com/list-of-ubuntu-unity-keyboard-shortcuts.html. As an alternative you can install the CompizConfig Settings Manager, either from the Ubuntu Software Center or from the command prompt (sudo apt-get install ccsm), and dig through the Ubuntu Unity Plugin, and other plugins for that matter, to learn the other shortcuts.

Is there a way to create a virtual drive in Ubuntu that contains multiple NTFS partitioned drives?

This would be a good resource if you wanted to get into the code: https://wiki.ubuntu.com/Unity/LauncherAPI

Quicklists

There are two kinds of Quicklists: the static ones which are always shown once on right-click from the launcher entry and dynamic ones which are only displayed once the application is started.

Static Quicklist entries

Adding a Static Quicklist entry is very easy, all you need is to add some support to the desktop file. This is based on the desktop file formats Action Groups.

Here is what needs to be added to gnome-screenshot to support Quicklist

[…] Actions=Screen;Window;

[Desktop Action Screen] Name=Take a Screenshot of the Whole Screen Exec=gnome-screenshot OnlyShowIn=Unity;

[Desktop Action Window] Name=Take a Screenshot of the Current Window Exec=gnome-screenshot -w OnlyShowIn=Unity;

Actions is referencing a Desktop Action. Each Desktop Action references an item entry in the Quicklist. Here, we have the "Screen" and "Window" entries, corresponding to :

[Desktop Action entry]

Then, each group have: 

a Name=, which is the entry as it's displayed which should be in title case.

an Exec= referring a command line to execute once clicked. Details on additional syntax.

OnlyShowIn=Unity is recommended to tell "show that entry in the Unity Springboard Quicklist" so that the file can be given upstream

without the possibility of showing up in other untested desktop environments. Please let upstream projects decide if they want to have this action shown more widely.

In the desktop spec there is a full desktop file sample with actions. Here is an example of a patch for gnome-utils using the old X-Ayatana style, but shows how to format the patch, with links to ubuntu bug and forwarded upstream.

xwindows working but not unity desktop

Try sudo dpkg-reconfigure lightdm.

If that doesn't work, try opening /etc/X11/default-display-manager in nano/whatever text editor you as root and replace whatever's in there with usr/bin/lightdm or "usr/sbin/lightdm. That should work after your reboot.

description

The unity program can be used to start the Unity shell as a compiz module, and to specify how to handle logging, debugging, as well as how to deal with the user’s profile.

options

--advanced-debug

Runs unity under debugging (using GDB or another debugger tool) to help tracking issues. Should only be used on request from a developper following a bug report.

--log filename

This parameter, followed by a path or filename, tells the Unity shell to store logs in the specified file.

--reset

This option allows the user to reset profile parameters in compiz and restart the Unity shell with default settings.

--verbose

This option turns on displaying additional debugging output for the Unity shell. It can be used by the user to debug configuration issues. This option is often used along with the --log option to save output to a file.
