When you install new printers on your Windows machine they might have the nasty habit of setting themselves as the new default printer. That may be fine if you intend to use that new printer a lot but can be a pain if you only use it once or twice.
To set another printer as default printer, follow these steps:
Open the Control Panel and go to Devices and Printers under Hardware and Sound. In the Printers and Faxes pane, right-click the printer you want to set as default and select the appropriate action:
Screen brightness is an attribute that is reset automatically upon rebooting your machine on Ubuntu and all its fellow distributions. Lucky you if you find the settings okay, but on notebooks and similar machines, you might want to lower the brightness, you it doesn’t suck your batteries dry.
To do that, open the following file as root via terminal:
sudo gedit /etc/rc.local
In there, enter the following line somewhere before the very last one that says “exit 0″:
echo 0 > /sys/class/backlight/acpi_video0/brightness
0 is the lowest brightness setting. You can adjust it to your likings!
Whenever you need to call executables from the command line, this is not possible unless you either have directed your console to its location with the cd (change directory) command, or have set it in the PATH variable. The Path variable is a string consisting of one or more data paths seperated by a semicolon and is used every time you call a command to enable the use of executables which are not in your current directory but in one of those you specified in the variable.
To add paths to it, right-click Computer on your desktop or your menu, hit Advanced System Settings and go to the Advanced tab. There, click on Environment Variables… and look for Path under System variables….
Edit it and add a path by placing a semicolon right after the last path and entering the complete path to the folder where your executables are placed.
