Capture whole screen

You should use PrtSc key.

When you press the PrtSc key, you can see this dialog to save it.

Capture specific region

You can use Alt+PrtSc key combination to capture activated window.

When you press the keys you can see this screen to save the picture.

If you want to capture specific region, you should install capture application, "Shutter" to save and edit the screen.

Install Shutter on Ubuntu software center

mount windows shared folder

mount –t cifs –o username=geek,password=thepass //geekmini/root /media/Video




mount smb folder


mount -t smbfs //user@server/sharename share 

Solving Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap"

When you running application that need Qt4 on Ubuntu 11.10 Oneiric, like PhantomJS or something, you will get kind of error :
Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
.

To solve this problem :

sudo apt-get install gtk2-engines-pixbuf

 

Start up slowly when I put gvim command.
http://askubuntu.com/questions/47393/gvim-gives-warning-unable-to-register-window-with-path 

It is a bug and has a work around.

gvim(){ /usr/bin/gvim -f "$@" & true; }

Synergy Server is working on Ubuntu and Synergy Client is working on Windows

My configuration
/etc/synergy.conf

add this to .gvimrc

 set gfn=Courier

.vimrc 수행후에 .gvimrc가 수행되는 구나.
