Get the Vendor ID and Product ID of TouchPack Resistive Touch Screen using ‘lsusb’ command.

person@CANONICAL-DESK:~/Desktop$ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1bfd:1688 TouchPack Resistive Touch Screen
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
person@CANONICAL-DESK:~/Desktop$

So, here is VID and PID of Touch Screen is:

Bus 002 Device 002: ID 1bfd:1688 TouchPack Resistive Touch Screen

VID = 1bfd

PID = 1688

Now, it requires quirks to work well with Ubuntu. Ubuntu is taking it as usbhid device. There are few ways to enable this device with quirks.

Modify /etc/rc.local file  and add below line:

modprobe -r usbhid
modprobe  usbhid quirks=0x1bfd:0×1688:0×40

Please reboot the Ubuntu, and next window will give you touch experience. Now, there are few applications in Ubuntu, that will make your user experience rich. There is application called “onboard”, comming in default Ubuntu Netbook Installation. That
will enable on-screen keyboard for every situation. You have to just enable it in start-up application so, GDM can launching new session. There is “onboard-settings” where you can define your optiont, like icon in Ubuntu Top Panel, your custom keyboard layout, launch it while locked  screen, etc… And for editor, there is very good application called, “xournal”, which you can installed straight from Ubuntu Software Center.

So, title contains Puzzle Number of that puzzle which i attended very first time.

Puzzle No:  255 July-21-2008(4)

What would be the value of X and Y to correct  X * Y * XY = YYY equation?

I was BASH freak, due to my Q/A Automation work @ Novell. So i thought, let’s not find one result, make it automated to find different possibilities of X and Y.  I decided to wrote BASH script with TRY / ERROR methodology.   Which took my 30 Minutes due to cosmetic changes. I was feeling top of the world because of my Hard Work + Smart Work deadly combo . I submitted my solution (Answer + Script). But, in next circular i was not in top five .

Then i did retrospective analysis of my failure, which helped me to manage  my name in top five for next few month. I also took part in Novell Test Fest 2008 by winning series of on-line quizzes. My team was  First Prize Winner in Novell Test Fest 2008. Then my friend, who had redirected me to that Puzzle Fame Game (For me at-least) came and told me that you are true winner, you have not used Google. I didn’t say anything, i just smiled 

Download script to solve Puzzle No: 255 July-21-2008(4) @ Novell: What would be the value of X and Y to correct  X * Y * XY = YYY equation? (Please don’t file any Bug ):

Answer of the puzzle and positive output from script with statistics:

Try & Error Count :  57

Possibility of X  :  3

Possibiligy of Y  :  7

So, YYY Would be  :  777

So, XY  Would be  :  37

So, X * Y * XY    :  777

Comparing Eqation X * Y * XY = YYY

RESULT = POSITIVE

So, Possibility of X = 3 and Y = 7 to make the equation X * Y * XY = YYY Possible!
