Make your gnome menus run faster

Some weeks ago, I have showed two small tips to tweak your Ubuntu Linux. The first one is to disable IPv6 and the second one is to reduce swapping. Today, I have another tip to make your gnome menus run faster.

1. Create a file named .gtkrc-2.0 in your home directory

cd
touch .gtkrc-2.0
echo "gtk-menu-popup-delay = 0"| tee -a .gtkrc-2.0

2. Logout and login again

I have tested with a value gtk-menu-popop-delay = 2000 before to try gtk-menu-popop-delay = 0 to see what is different in effect.

How to disable tap-clicking with your touchpad in Linux in a easy way

Lots of people have a love/hate relationship with their touch pad on their laptops. It’s great for speeding around your screen and doing lots of cool things with nary a mouse in site. It’s horrible when you accidentaly double-click that Quake 3 icon while your boss is strolling into the room.

Here’s a quick and easy guide to disabling tap-clicking and scrolling on your touchpad. With this little hack you’ll still have a mouse replacement, but will avoid Quake 3 inspired embarrassment.

First, you’ll need to edit your xorg.conf file. This is the file that controls your display, and oddly all of your input devices as well like your keyboard, mouse and…. touchpad. Open up a CLI (Applications-> Accessories-> Terminal) and let’s get down to business.

gksu gedit /etc/X11/xorg.conf

Now you’ve got your xorg.conf file open in an editor, let’s add one line too it. Look for this section in your xorg.conf file:

Section “InputDevice”
Identifier “Synaptics Touchpad”
Driver “synaptics”
Option “SendCoreEvents” “true”
Option “Device” “/dev/psaux”
Option “Protocol” “auto-dev”
Option “HorizScrollDelta” “0″
EndSection

Yours may have all of this stuff or it may have very little of it. The key points you want to look for are the Section and EndSection bits. Everything has to go between these two, and what we’re going to add is not exception.

See the Options above? We’re going to add an option. So cut and paste the following in there just above the EndSection portion:

Option “TouchpadOff” 2

Now save your file and exit Gedit. The next time you restart your laptop (or restart your X session) you’re touchpad will be click-less.

But perhaps this way is so complicated and sometimes it doesn't work! Then you should try this way:

For KDE:
1. Open KDE Control Center
2. Select Peripherals > Touch Pad
3. Select “Tapping” tab and uncheck “Enable Tapping”
4. Click “Apply”
Done

For Gnome:

sudo apt-get install gsynaptics

And go to System > Preferences > Touchpad

Done

tCtrl+Alt+Backspace重启x-window后,桌面的图标一个也不显示了，而且自已定义的快捷键也全部失效。
还好，firefox可以打开，于是上网搜了一番。gnome下刷新桌面的方法：

Code:

killall nautilus

试了一下，显示：

Code:

nautilus: no process killed

看来nautilus这个程序是关键。于是直接运行nautilus，桌面图标马上就显示出来了。
接着Ctrl+C，桌面一闪然后就又一切正常了。看来nautilus还智能的。
