Restoring TouchPad actions in Laptop – ubuntu linux


From today morning, The TouchPad in my IBM T410 laptop was not working.

It was very tough to work on laptop without the touchpad.

Searched in net and found a solution to make it work.

We have to unload and reload the kernel module for the touchpad.

Here are the commands to execute.

sudo rmmod psmouse
sudo modprobe psmouse

If there is no terminal window open, you can use one of the following:

In Gnome or KDE, press Alt + F2, type gnome-terminal and press Enter
Press Control + Alt + F1, login with your username and password, type the commands, then press Control + Alt + F7 to get back to X

After running the second command 4-5 times, the touchpad started to work. :-)

Read Your SD card with your ubuntu laptop


Nowadays, laptops comes with Inbuild SD card reader. I too have Ricoh Card Reader inbuilt with my Lenovo R61i Laptop.

My Friend Elango.S, a Hardcore Windows user, is becoming a big fan of ubuntu. Hmmm. That is the power of Ubuntu. It is like AR Rahman’s Music.  First it may hard to look and get to used with. But, as we keep on living with it, it will become a great companion in all times, till our life. :-)

Elango is pinging me often to get some little how-to do the things in ubuntu. He is an alwasys-ready-to-learn guy. so the transition from windows is a breeze for him. He is wondering the ubuntu’s powers.

This post is the answer to his query on how to make use of the inbuilt SD card reader. Ubuntu 9.10 does not reads it by default. So what? Google is there. Ubuntu community is there. :-)

Get the details on Card Reader.

shrinivasan@shrinivasan-laptop:~$ lspci | grep Card

15:00.5 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 11)

Googled as “http://www.google.co.in/search?q=Ricoh+Card+Reader+ubuntu”

Got the solution in the very 2nd link.

Do the following things.

1. Backup the file /etc/modules

sudo cp /etc/modules /etc/modules.bak

2. Add one line to /etc/modules

gksu gedit /etc/modules
or
sudo vi /etc/modules

3.Tag this on to the end of the file in a new line:

tifm_sd

When you restart, you’re card reader will be functional. You’ll see that when you slap an SD card into the reader, it will automount.

But wait, don’t want to have to restart your machine? Go back to the terminal you impatient person and type:

sudo modprobe tifm_sd

Thats all. After a restart, My laptop recognized the inserted SD card and opened the SD card in Nautilus. :-)

Yes Elango. Ubuntu will make your life easier, just like a sweet music. Enjoy the Freedom with Linux.
