Recovering a lost Windows Serial Key…

During Repair of Dell XPS Laptop, I lost Windows 7’s
Cover, which I got as Upgrade from Vista (so no
sticker on laptop). It includes Windows Serial No.
It lost this morning, and I installed Windows
without this key, but as need to activate within
30 days, I have to find some solution.

Two Software I found for this work (as I had already
installed Windows 7 on my old bad sector hard disk)
Belarc Advisor
It has Free, Personal Use, working perfect
Free for Demo, not perfect and PAID:-)

Finally, I attach old harddisk, boot windows 7 (old installation),
install both software, Recover-keys find few things
Office, Call for Duty and 1 more, but now Windows key,
Then install Belarc Advisor and it create report and
show me in Web browser, yes it contains Windows keys
with IE serial key. So I got the key to Windows Activation.
It save money and something that Punjabi don’t like to do…;-)

Maemo 5 on Desktop

I was trying to get Maemo 5 device, but
finally I got easy method to install it on
desktop machine with help of instruction
over here.

I am working to find a way to include Punjabi (and other
Indic) language to device. Few steps I completed:
Locale-Extras – Updated all Indic locale files
Indic – Project to include all i18n stuff for Indic languages
Keyboard Layout – Virtual/On-Screen Keyboard (which has no Indic support yet)

still I am not able to add my language in it, but find few things
different from my desktop machine:
more time required to work on this, but I have next Internet
connection in coming weeks.
This system setup on Ubuntu AMD64. Often forgot to
put variable vdso32=0 for kernel at boot time.

HP Touch Tx2z and Fedora …

Finally I got AMD Based Laptop and it is
Touch Screen Display, which is quite good
for Windows Vista (Pre-installed), but Windows
Vista was too slow to use (most of Junk
Softwares, thanks to HP).
Finally I installed Windows 7 RC and Speed is quite good,
but not equal to Dell Studio XPS 13 with Intel
Core 2 Duo P8600 (2.4Ghz) (HP has DDR2
and Dell has DDR3) even difference is
not big enough to feel in first look.

My Final Target to get install Fedora or Linux
on HP tx2z, first I tried Fedora 11 (x86_64), which
install quite easy and during installation pointer
moved by touching the screen, but Click
was not working.
Fedora 11 installed, pointer moved, but
Click was not working. Finally Upgrade
that to rawhide (Fedora 12 pre-release),
but that is NOT Working at all. Even wonder
was that there was no /etc/X11/xorg.conf file
at all. But GUI was working. with
system-config-display, xorg.conf file generated
To Fix the issue, I used Ubuntu Website,
where they fixed Xorg.conf file to fix issue
Following Steps I used for it

1) /usr/share/hal/fdi/policy/20thirdparty/10-wacom.fdi



Changed to

  <!-- N-Trig Duosense Electromagnetic Digitizer



2) N-trig Symlink
edit (create New file)


and add following line

KERNEL=="event*", ATTRS{idVendor}=="1b96", ATTRS{idProduct}=="0001", SYMLINK="input/n-trig"

3) Finally my ‘xorg.conf‘ (/etc/X11/xorg.conf) is here
[ahawk@ahawk ~]$ cat /etc/X11/xorg.conf
Section “InputDevice”
Identifier “stylus”
Driver “wacom”

Option “Type” “stylus”

# Developed with Ayuthia (using Rafi Rubin’s Wacom sections as a starting point).
(ya, I have not developed, but all step are from Ubuntu site, for Detail
instruction you can visit here)

Just for Information: I have Windows 7 Firmware Updated.

Next testing I would like to go for OpenSUSE, which has
ability to configure Touch Screen Dispaly within YaST, while
Fedora Has Nothing for try.

Fingerprint reader I failed to Configure in Windows 7 as well
as in Fedora Rawhide. Work continue if get some fix.

Using automatic login with Fedora

I am using Gnome as desktop f rom some time, while not

big fan of gnome. GDM (gnome display manager) is

default manager. When it is changed to new source code,

there is not Graphical option to configure automatic

login with this. I was trying various time to search

automatic login feature (but I am not command line

user or expert, so not like to change configuration).

finally I got a solution for this. to do this you have

to do following steps:

1) Change GDM->KDE

2) change KDE configuration for Automatic login

3) by KDM, change desktop to Gnome (if you want to

use gnome)

1) easy method is to remove gdm with all dependency

$yum remove gdm

while make sure kdm installed on your machine

2) run systemsettings->Advanced->Login Manager

after application opened, go to Convenience (7),

select “Enable Auto-Login

User “”

“Lock session”

3) reboot your machine and you will be auto login

with selected user. it will default go to KDE, but

you can use gnome by Logout, select “Session” and

select “Gnome” and afterward you will be automatic

login to gnome session.

there can be various way to do this, but as I like use only

Graphical Interface for most configuration, so I tried this.

ya, kdm package need to install to work this, which will

pull some kde application.

Nvidia Driver for Fedora on Dell xps

as per last post, On Dell Studio XPS 13
kmod-nvidia was making small problem
to hibernate and other issue,
searching for solution. Need to

download latest Nvidia Driver

I installed “”
packages and it helped to fix me the problem.
it need to install without running X server.
Alt +F1 (or F2/F3) is not only working.
‘init 3’ also not working. need to remove
/tmp/.Xorg* files and then only driver started.
It required kernel libraries and then
complete automatically for it.

‘init 5’ command started new interface
and it looks good than ‘kmod-nvidia’
driver somehow. Following problem fixed

1) Hibernate working fine

2) Sensor for GPU is working fine
(4th with Red strip is Nvidia – 62C is too much)
3) Display seems Good to eye then pervious

4) System->Preference-> ‘Nvidia X Server Setting’
(it has various setting for X Server)
