Change TTY Resolution
This is a comprehensive HOWTO to change your TTY (Ctrol+Alt+F1) and bootscreen resolution. I am sure we have all noticed the low resolution used while Linux is booting up, and also of the TTY (Ctrol+Alt+F1). The resolution of the TTY is set as a paramater given to the kernel before it loads. GRUB is responsible for booting the kernel, so we need to tell GRUB to tell the kernel what resolution we want. GRUB’s list of boot options is contained in the file /boot/grub/menu.lst.
How to disable Ctrl+Alt+Backspace from restarting X
First you need to take backup of xorg.conf file using the following commandsudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
Now you need to edit the file using the following command
sudo vi /etc/X11/xorg.conf
Add the following lines at the end of file

EndSection
Save the edited file
Colored ls Output
Unix uses the ls command to list the contents of a directory. By default ls displays all directories and files the same way, leaving you without the ability to quickly determine what type of files you are looking at (in Unix everything is a file).
Customizing Your Bash Prompt
Customizing the default shell prompt not only makes the terminal that much more exciting, it will also help you remember which system you are currently on and the directory you are about to run a command in (Yea!, no more incessant pwd commands). This is especially useful for those late night pesky phone calls letting you know that you have to come into work early, really, really early; to fix the server that the underpaid incompetent third string sysadmin was supposed to be watching! Arriving on site with multiple windows open mixed with sleep deprivation can have some very devastating results. Running shutdown or init in the wrong window can really hurt.
Kicker’s hidden tweaks
KDE is one of the most popular and used desktop environments for Linux systems because not only that it looks very much like Microsoft Windows, but it combines ease of use, superb graphical design and new age functionality with high-end technologies of the Unix-based operating systems. Kicker is one of the core parts of the KDE desktop, it is the main panel. This panel can be customized by users in almost every possible way you think of. For example, you can add a lot of useful applets (clock, system tray, show desktop, color picker, desktop preview & pager, dictionary and many more), application shortcuts or you can make it completely transparent
Kicker also has a lot of configuration options that are not revealed in any of the existing graphical user interfaces but can be very useful for advanced users. You must know first that these options are found in the /usr/share/config.kcfg/kickerSettings.kcfg and the /home/yourusername/.kde/share/config/kickerrc configuration files. Below are some of the top tweaks found in the kickerSettings.kcfg file, but nothing stops you to read and modify, as necessary, every option.
Make Conky Transparent in KDE
Conky doesn’t display properly with a transparent background in KDE, this is a rather quick fix. Type the following in the command line:
feh –bg-scale `dcop kdesktop KBackgroundIface currentWallpaper 1`
If you use a centered wallpaper, use –bg-center instead.

Make Conky Transparent and movable
Conky is a light-weight system monitor. It’s in most the repo’s for most distributions. I personally like conky to look as if it’s part of my actual desktop. Unlike gdesklets or other desktop widget applications, i want it to feel like it’s part of the desktop itself, where it doesn’t get in the way of other windows as well as to adding some eye candy as well. But it’s also nice to have the ability to move it when necessary as well. There are times (or at least there are for me) when it might be nice to shift conky slightly, so I can see what’s happening without shifting other windows around.
To that end, I cooked up a .conkyrc file that displays a 200-pixel wide panel with the traditional system indicators in place, plus the settings that float it on the first workspace of my Fluxbox setup. This way it doesn’t get in the way of other windows, but it’s still moveable as well.
