The Windows 7 games index, which is accessible through Games in the main menu, usually imports all game executables that are installed on your system. But if it fails to recognize a game, it can be difficult to figure to figure out how to add it afterwards.
The trick to add items is to look for the executable of it, which is located in the folder you installed it in, and to just drag and drop it in the Games window. To hide it again, just right-click it and select the appropriate option.
It may occur that by default your computer won't connect to wireless networks after starting up the system. A way to solve this might be to install the WICD network manager which is available in the Ubuntu repositories.
Just fire up Synaptic Package Manager and search for WICD.
During installation, you will be asked to add system users to the netdev group - check the users that you would like to use WICD with:
Proceed with the installation and launch WICD through Ubuntu's/Mint's main menu. In the program's interface, check the network that you would like to connect with on system startup and try it out by rebooting your machine.
A connection should now automatically be build with the chosen wireless network.
Linux Mint 13 plays a sound when you start the system as well as when you log into an account. Both of these sound can be changed - to do so, you must be logged in and know the root password.
- Open the main menu and go to Administration > Login Window.
- Go to the Accessibility tab:
You can now check or uncheck the listed sounds or choose new ones from your files - these must be in the .ogg format however! System sounds can be found in /usr/share/sounds/LinuxMint/stereo for example, or you can convert your own files.
By default, the sound that plays when an account logs in is disabled on Ubuntu 12.04. To turn it on again, you need to add the command to startup-applications again. To do so, click on the cog-wheel icon on the top right corner of the screen and click on Startup Applications...
On the appearing window, click on Add. Enter a descriptive name for the entry and the following into the command line:
The term in quotation marks, desktop-login, is the name of the sound that is played - you can change that to anything you want (it has to be in the .ogg format and positioned in /usr/share/sounds/ubuntu/stereo).
Usually Google restricts its results to the language you have set for the page itself, which is the one spoken in the country it locates you in by default.
You can easily change these settings by clicking on the cog wheel icon on the top right and going to Search Settings:
Next, click on Languages on the left pane and add any of the languages listed by checking the box next to them. If you want to use one language only, you need to change the language the page is displayed in - the same language will then be selected for the results.
Afterwards click on Save on the bottom right corner.
If for some reason, you have a wireless connection stuck in your system's selection that doesn't go away, it's not that easy to figure out how to do so:
To remove such an entry,
- left-click on the connections icon and on Open Network and Sharing Center
- in the left pane, click on Manage wireless networks
- click on the network you want to remove once
- click on Remove network above the list
VirtualBox machines usually have two bars in their window to make working with them easier.
These however are a great disturbance if you want to take screenshots of your machines - even if you select to leave the window border, the menu bars will still be on them.
To remove the bars, it only needs a simple terminal command. Open one and enter following (make sure that no virtual machines are running):
/usr/bin/VBoxManage setextradata global GUI/Customizations noMenuBar,noStatusBar
Next time you start a VirtualBox vm, there won't be any menu bars. To restore them again, enter following into a terminal:
/usr/bin/VBoxManage setextradata global GUI/Customizations MenuBar,StatusBar
Ubuntu, other than most distributions as well as MS Windows, decided to move its window menu buttons to the left side of the top window panel. This brings along many accustomization problems for people who are used to rush their mouses to the top right instinctively.
If you want to, you can revert this change with the help of gconf-editor.
Open it by entering gconf into Dash or
into a terminal. Browse the left pane for /apps/metacity/general and look for the value of button_layout which should be close,minimize,maximize: . This value defines where the buttons are positioned and in which order - the commands stand for the appropriate button whereas the colon determines on which side they will be. You can also add a menu button by including menu.
To move the buttons to the right and adjust their order, a value like
would be appropriate. Don't forget to set the colon or metacity will crash as soon as you have entered and confirmed your value!
The selection box that appears when you hold the left mouse-button and drag your mouse away is blue by default on all versions of Windows. However you can change this setting by using two registry values in Windows 7 and Windows 8.
Open the registry by typing regedit into the Windows 7 menu search on Windows 7 or by right-clicking the bottom left corner on Windows 8 and opening a Run... prompt. Enter regedit into it.
- In the registry you will see a tree structure on the left pane - in it, browse for Computer\HKEY_CURRENT_USER\Control Panel\Colors and click it once.
- On the right pane, look for the value of HotTrackingColor. It is given in three values representing the ratios of red, green and blue that range from 0 to 255. Enter values that mix to the color you want to have (you can check the color values in a graphic editor).
- Do the same for he value of Hilight.
These two values also alter the color of hyperlinks and the color of highlighted text. After you set the values, close the registry and reboot your machine. Afterwards the selection box should have the color you chose.
The two different values each stand for a different part of the box - the first determines the color of the inner transparent space, the second determines the color of the non-transparent border. This means you can have different colors for each.
Gnome-Screenshot is the default tool to take screenshots on Ubuntu and Mint and brings a great deal of functionality. While it also has the ability to exclude the mouse pointer for screenshots if you use the graphical interface, you won't find this feature if you want to take them from the command line - the only option to exclude them there is to set the option as default which is possible with dconf-editor.
If dconf-editor isn't installed on your system yet, install it by entering the following into a terminal:
sudo apt-get install dconf-tools
Afterwards you can change the default behaviour of pointer inclusion with
dconf write /org/gnome/gnome-screenshot/include-pointer false
If you want to revert things, just set it to true again:
dconf write /org/gnome/gnome-screenshot/include-pointer true
Next time you open the GUI or take a screenshot via PrtScr or the terminal, the mouse pointer won't be included on the screenshot.
