Linux Tips

1. Open the document that contains your artwork and prepare it for conversion. Save a copy in the same folder; using a copy will let you start over if something goes wrong. If necessary, clear any background color. You may have to use "Add Alpha Channel." If you plan on making an arrow-type cursor, move or rotate the artwork so the "tip" of the cursor is in the upper-left corner of the image. Make the "canvas" perfectly square, so that height=width, being careful to not distort your artwork. The artwork should cover at least one-third of the canvas, regardless of actual size. 2. Scale the image to 32 pixels in size, keeping it square and save it as a PNG image. Name the image after your artwork but also to remind you of what kind of cursor it is. The example is a default arrow-like cursor called "arrow.png". 3. Launch a text-editor to open a new text file; use "Save As..." immediately, giving it the same name as your cursor ima...

With the power bestowed upon us, we can create a Linux file system in a file. Humanly speaking, we can create a file containing specific file system and mount it as if it were a partition of a hard drive. To do this, we must first create the file: touch filename Then run the dd command to give a file size: dd if=/dev/zero of=/tmp/ filename bs=1024 count=102400 In this example a 100 MB file will be created in /tmp. You can modify the parameter "of" to change the location of the new file and parameters "count" and "bs" to change the file size. Now give it to our file format with the file system you want. Ext3 For example: mkfs.ext3 filename After the file created and formatted, it is now ready to be mounted: mount -t ext3 /tmp/ filename /mnt/ filename -o loop As you may know, the parameter "-o loop" should be used as the file is not a "Block device" or block device. Clever. We already have our system file nested within the main filesys...

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...
