I am sure that this might have happened to you also, when you tried to install a package, and then a message showed "Failed dependencies". Now use apt-rdepends to know the dependencies and their dependencies of a package. When we make a query for dependencies of a package, apt-rdepends searches the APt and return the list of dependencies and the dependencies of each dependent package. insatll Install apt-rdepends $ sudo apt-get install apt-rdepends Lets see the dependencies of vlc $ sudo apt-rdepends vlc vlc Depends: libaa1 (>= 1.4p5) Depends: libc6 (>= 2.8) Depends: libdbus-1-3 (>= 1.0.2) Depends: libfreetype6 (>= 2.2.1) Depends: libfribidi0 (>= 0.19.2) Depends: libgcc1 (>= 1:4.1.1) Depends: libgl1 Depends: libgl1-mesa-glx Depends: libglib2.0-0 (>= 2.12.0) Depends: libgtk2.0-0 (>= 2.8.0) Depends: libnotify1 (>= 0.4.5) Depends: libnotify1-gtk2.10 Depends: libqtcore4 (>= 4:4.6.1) Depends: libqtgui4 (>= 4:4.6.1) Dep...

Create your own login screens in ubuntu.. Components of a GDM Theme A GDM Theme is basically composed by: * A background image * A screenshot to be displayed in the GDM Configuration * Icons (images for the icon bar) * An xml file, where the actual theme is defined. This file allows the declaration of frames, images, the login box, caps lock warning frame, background, icons, multi-language captions, etc. * The GdmGreeterTheme.desktop file, which is not a true .desktop file, but it contains the name of the xml, screenshot and other information to be displayed in the GDM Configuration screen. 1. Create a theme directory... $ mkdir mytheme $ cd mytheme 2. Now copy the images to the directory and create a the xml file.... $ vi mytheme.xml In general, the first item to be changed is the background image. The background image must be at least as big as the screen resolution. In order to make the theme suitable to other users, it is a good idea to use at least 1600x1200 pixel images, as...

Download the tar file from here . ...and extract it.... You can see many image files, one c file, one Makefile and one bdf file. To create a usplash using this...just type at terminal... $ cd dipin-usplash2 $ make Now you will get a dipin-usplash.so file. This is the usplash file. Now u can create your own usplash by editing the images and call 'make'. Edit the images as said below... Put all the images into one image and do this...then extract the palette of the image, and then apply that palette to all individual images... 1. Windows->Dockable Dialogs->Palettes 2.click the arrow on the top-right of the palette-dock.... 3.Palettes Menu->Import palette 4.Click image..and select the image... 5. now the new palette would have been generated....as show... 6.Now take individual images and do this... Mode->Indexed 7. Colors->map->Set Colormap.. 8. 9.Select the palette we generated.... 10.

Occasionally, I'll download an image file and want to see what is on it, or make a few changes to it before burning it to CD. The image file (dd, iso, etc) can be mounted using the loop device. You will need to know the type of filesystem the image uses. Most Linux/Unix-based OS's have an application that will help you identify the filesystem type. Debian includes the command /lib/udev/vol_id, SUSE has the same command but in a different location (/sbin/vol_id). If you know how to get this information on a SUN box, please leave a comment for us. If you don't have a command that will tell you the filesystem type, you can guess. Most images downloaded from the Internet will be iso9660, Windows filesystems are normally ntfs, Linux are commonly ext2, and Macintosh are udf or hfs. As a last resort, you can work your way down the list of filesystem types listed in the mount man pages. After you know the filesystem type, you are ready to mount. Note: replace   with the filesystem ...

# rm  filename  (removes a single file) # rm  filename ? (matches single character. e.g.  filename1 ,  filename2 , filename3 ) # rm  filename [1-5] (matches  filename1  thru  filename5 ) # rm  filename * (removes everything that matches  filename . e.g. filename122, filename222, filename.backup ) # rm -rf /home/esofthub/ directoryname  (the -r deletes  directoryname recursively and all its contents without prompting (-f) read only files/directories) # rm -Rf /home/esofthub/ directoryname  (the -R deletes directoryname  recursively and all its contents without prompting (-f) read only files/directories) # pwd Note: Make darn sure you're in the right directory!! For example, you might be inadvertently deleting the contents of  /etc  instead of user defined etc, such as,  /tmp/etc/  or  /raid/etc or /home/esoft/etc . # rm * ((wildcard *) removes everything within a directory # rmdir /home/esofthub/ directoryname  (deletes empty directories)

The following command help you to find the disk space used by different packages in ubuntu open a terminal window and run the command dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}' That will sort the packages by size, putting the largest ones on the bottom. you can pipe(|} the output for last 10 by using | tail -n 10 at the end of the command
