The Opera browser uses mouse gestures that allow the user to navigate through tabs and tab histories with the help of mouse-clicks and -movements. This can be a hindrance however if you are used to control the browser with its own graphical interface and often just play around with your mouse out of boredom.
To disable these gestures you simply need to open an Opera window and go to Settings > Preferences > Advanced > Shortcuts and uncheck the Enable mouse gestures checkbox.
Every service you install is usually run on system startup. Sometimes these services do so without asking you before and sometimes they might even be malicious or just too heavy in resources. To select specific services that shall not be started by boot, open msconfig by calling a Run prompt through the main menu and entering msconfig.
Switch to the Services tab and uncheck any services you don't want to start anymore, afterwards click Apply and restart your machine.
If you have some peculiar program installed that you need to have but want all its internet communication blocked you can do that easily with Windows' built in firewall. On Windows 8 just hit the Windows key to get to the main menu and
- type Firewall.
- Click on Settings on the right pane and
- go to Windows Firewall.
- Click on Advanced settings on the left side of the window.
- On the left pane of the new window, right-click on Outbound Rules and
- select New rule...
Now follow the setup wizards few steps to set the rule up. That's it! If you happen to need to deactivate the rule for a short time, you can just right-click it and do so:
The screen-keyboard is a useful Windows feature on some occasions, e.g if you want to find out if it's the new keyboard's drivers that suddenly make your machine crash, or when you just need to unplug your keyboard for other reasons.
However it can happen that, if you turn on the screen-keyboard a few times on the login screen, it will stick to the desktop and open up every time you log in (be it a bug or adapted behavior). This is annoying if you just unplugged your keyboard to test stuff.
But fortunately we can turn that behavior off easily in the Control Panel:
Open it up and go to the Ease of Access section. Under Explore all settings, click on Use the computer without a mouse or keyboard:
Now uncheck the Use On-Screen Keyboard check-box under Type using a pointing device:
Click OK to save the settings and you're done!
The past versions of Firefox brought a feature to it that a great deal of users didn't like because it changed the way tabs are handled in a window. Instead of just showing all tabs at once, Firefox now adds horizontal scrolling to the tab bar in order to prevent the tabs from becoming too small to read its name. That way you can always see what's on your tabs but don't have a complete overview of the whole bar anymore.
In order to help out on that an add-on was created that increases the number of tabs that are visible before the overflow scrolling occurs.
It's called Prevent Tab Overflow and you can find it in the Firefox Add-On database: https://addons.mozilla.org/en-US/firefox/addon/noverflow/
Add it and it will get to work instantly. Have a look at the Add-on preferences (Tools>Add-ons>Extensions>Prevent Tab Overflow>Preferences) to see what you can actually do:
While the add-on cannot prevent tab overflow as whole, it can resize the minimum tab width down to 40 pixel (the default in Firefox is 100 pixel). A lot more tabs fit in that way and the scrolling kicks in on a point where it actually makes sense not to shrink the tabs any further.
One of the most unnecessary things that Windows 8 brings to desktop computers might be the lock screen you need to wipe away every time you start your machine - luckily it's also one of the things you can disable.
To do so, open the Local Group Policy Editor (as shown here).
Browse the left pane for Computer Configuration > Administrative Tools > Control Panel > Personalization and double-click Do not display the lock screen on the right pane. Enable the setting and confirm by clicking Ok!
The default settings in the Unity desktop environment move a window's control panel away from the actual window up to the top panel of the screen - this is called 'global menu'.
Since that is a major change of paradigm and might hinder your workflow if you decided to switch, here is how to reverse the settings:
Open a terminal and enter following command:
sudo apt-get autoremove appmenu-gtk appmenu-gtk3 appmenu-qt
Afterwards you need to log out or reboot your machine. To enable it again if you should change your mind, just reinstall the packages:
sudo apt-get install appmenu-gtk appmenu-gtk3 appmenu-qt
If you are one of those who like to deal with inserted DVDs, USB keys and other removable media yourself, the Autoplay feature of Windows will most likely do nothing but being clicked away by you.
If you want to save yourself a pop-up and a click you can disable Autoplay. To do so, open the menu and type in gpedit.msc. The group policies window will open and you'll see a navigation pane on its left. Browse it for
Local Computer Policy > User/Computer Configuration > Administrative Templates > Windows Components > AutoPlay Policies
Pick User or Computer Configuration depending on the range you want your settings to have. On the right pane, there should now be some settings, on of them being Turn off AutoPlay. DOuble-click it for the configuration window to open.
On the left, click the Enabled radio button. On the options pane you can choose between turning AutoPlay off for all media or just for CDs or removable media drives (since those are the most common I'd recommend to choose that). When you're done, click Apply and exit the group policies. Next time you insert something you won't be bothered with pop-ups.
If you install lightdm on distributions other than Ubuntu you may want to have the Ubuntu logo in the lower left corner removed or altered. This can be done easily by editing the original picture file which is located in /usr/share/unity-greeter/ (remember to open the folder as administrator, or do it right from a terminal as root).
The file you want to edit is logo.png. You can either rename it, so it doesn't show up on login anymore (for example, rename it to logo.png.bak - if you want it back, just remove the new extension again), or edit it with a graphical editor right away so that it reads something more appropriate to your distribution or login screen.
Ubuntu's login manager, lightdm, offers a guest login option by default.
Most of you won't use it anyway, so why keep it at all? You can disable that entry in the lightdm configuration file, which is /etc/lightdm/lightdm.conf. Open it from a terminal using
sudo gedit /etc/lightdm/lightdm.conf
At the bottom of the file, insert following line:
Afterwards, restart your machine and the guest login option will be gone. To bring it back, just erase the line again or set it to true.
