When I was pressing any key on the Num Pad then instead of the number getting typed, the mouse was moving or nothing was happening. This is how I fixed it.
1–> Open System–>Preferences–>Keyboard
2–> Select Mouse Keys tab.
3–> Uncheck the option: Pointer can be controlled using the Key Pad
Well, due to some reasons this problem started on my Laptop. Whenever I tried to open any folder from the Places menu (except Computer) , it used to open the folder in VLC Media Player and used to play Media Files (if any) present in the folder. It was irritating. I restarted my Laptop considering this will solve the problem, but the problem was still present. I have solved the problem now, and this is how to fix it:
1–> Open Computer from Places Menu.
2–> Now open File System–>home–>Any Folder
3–> Right Click on any folder present and select Open With Other Application.
4–> From the Windows just opened, select File Browser. Also check that the “Remember this application…” option is checked.
Now try opening any folder from your Places Menu, and you will find that everything is working perfectly.
To view the different things that you can do with Ubuntu Graphics, check this video:
Impressed? Well, you can do the same things to your Ubuntu using the software named compiz-fusion. But before that, you must fulfill the minimum requirements which are:
- You must have a Graphic card (NVidia, ATI or any other)
- You must have the drivers for the card installed.
To check whether the drivers for your graphic card are installed or not, do this:
1–> Open System->Administration->Additional Drivers
2–> It will then search for the latest drivers (or installed drivers) for your graphic card.
3–> From the list see if the driver for your card is installed or not.
4–> If driver is installed, click on close, else select the recommended driver and click on install. It will download the recommended driver and install it. Once the installation is complete, you have to reboot your system.
Once the driver has been checked, follow these steps to install compiz-fusion:
1–> Open Synaptic Package Manager from System->Administration->Synaptic Package Manager
2–> In the quick search box, type simple-ccsm.
3–> Select the simple-ccsm package and install it and all its dependencies.
Once installed, this is how to use compiz-fusion:
1–> Open System->Preferences->Appearance.
2–> From Appearance Preferences, select Visual Effects.
3–> Now select option Custom and click on Preferences.
This will open the Compiz-fusion Setting Manager.
Once this is done, you can open Compiz-fusion Setting Manager from:
System->Preferences->CompizConfig Setting Manager
or press alt+F2 and enter ccsm
Play around, change the configuration and enjoy!
On Feb 18th, I finally bought Reliance Netconnect Broadband+ after a lot of research. The main thing that made me buy this product was that due to certain reasons I was not able to install other USB Modems on my Windows 7 OS. I was not able to install IDEA net setter , neither Tata Photon Plus. But Reliance Netconnect was getting installed (used my brothers USB for 15 days), and hence I decided to buy it.
The trouble started when after buying Reliance Netconnect Data card (Huawei EC150), I was not able to install it on Windows 7 and hence I decided to switch to some other OS and then came Ubuntu to my rescue. I tried installing it on Ubuntu and there was no installer provided for the same. After searching I came to know that Ubuntu does not supports Modems, and hence was not identifying my Modem. After trying for 28 Hours, I finally succeeded in Installing Huawei Modem on Ubuntu. If you are facing the same problem, follow these steps:
1–> Open the terminal and run this command:
sudo apt-get update
2–> Now we need to install wvdial, so run the following command:
sudo apt-get install wvdial
3–> Now we need to install libusb-dev so run the following command
sudo apt-get install libusb-dev
4–> Now we need to download usb-modeswitch and usb-modeswitch-data so go to the following links
Download both the files and save them on your computer.
5–> Now extract both the files.
6–> Change your directory to usb-modeswitch directory and run the following command:
sudo make install
7–> Now run the following command:
sudo gedit /etc/usb_modeswitch.conf
It will open a file in gedit, remove all content in the file(if any) and then paste this text:
# Configuration for the usb-modeswitch package, a mode switching tool for # USB devices providing multiple states or modes # This file is evaluated by the wrapper script "usb_modeswitch" in /lib/udev # To enable an option, set it to "1", "yes" or "true" (case doesn't matter) # Everything else counts as "disable" # Disable automatic mode switching globally (e.g. to access the original # install storage) DisableSwitching=0 # Enable logging (results in a extensive report file in /var/log, named # "usb_modeswitch_" EnableLogging=1 # Huawei, newer modems DefaultVendor= 0x12d1 DefaultProduct=0x1446 TargetVendor= 0x12d1 TargetProduct=140b CheckSuccess=5
Now save the file.
8–> Now run the following command and it will again open gedit and paste the above text in it again and save it.
sudo gedit /etc/usb-modeswitch.conf
9–> Now run the following command:
sudo gedit /etc/wvdial.conf
It will again open gedit. Now you need to paste the following text in it:
[Dialer netconnect]New PPPD = yes Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Modem Type = USB Modem Baud = 460800 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 Username = 93******** Password = 93********* Phone = #777 Stupid Mode = 1 Auto DNS = 1 Check Def Route = 1
Change the username and password with your 10 digit MDN number given on the box of the data card. Now save the file and reboot your computer.
10–> After rebooting your computer, wait for 5-6 seconds and then insert your datacard. Now notice the Internet connection notifier at upper right corner of your screen. If it is trying to identify the network then do nothing and wait for connect to establish. If it doesn’t try to identify any network then run this command:
sudo wvdial netconnect
After you run this command you will see something like this
–> Using interface ppp0--> local IP address 22.214.171.124 --> remote IP address 126.96.36.199 --> primary DNS address 188.8.131.52 --> secondary DNS address 184.108.40.206
Open your browser and enjoy!

Few days back, I removed Zimbra from my OS. After removing it, I found few problems with my OS. My documents and games folders were gone, and my Desktop was showing contents of my Home folder. When I deleted something of the Desktop, it was also deleted from my Home folder. I tried to find a solution for the same, and here it is, if it doesn’t works for you, let me know.
1–> Check if you still have a “Desktop” directory inside your Home. If not, create one.
2–> Open terminal and write this command:
It will open a configuration window. In this window browse to apps/nautilus/preferences, and see if the “desktop_is_home_dir” key is enabled. If it is, then disable it.
If its already disabled, then write the following command in terminal:
and make sure it has the following entry:
3–> Restart the computer.
