This line appears near the top of the file. What you re interested in hereis the number. In most mainstream Linux distributions, the number 5tells Linux to boot into the GUI, and the number 3tells Linux to bootinto the command line. In the preceding example, therefore, I boot intothe GUI. 5.Change the number in this line. If it s a 5, change it to 3, and vice versa. Make sure that all colons andother items are left properly in place, or else your machine will haveproblems booting later. 6.Save and exit the file. The changes go into effect the next time you reboot the system. If you do end up having problems booting the system, in many current Linuxdistributions (including the one that comes with this book) your installationdisk can be used as an emergency boot disk. Check your documentation forinformation about the distribution you re using if it s not Red Hat 10. Changing your boot environment just for nowAt any time, you can have your Linux box switch between full command-linemode and full GUI mode. The instructions I give here assume that you re usingFedora, Mandrake, or SuSE. (Knoppix, Linspire, and Xandros don t give youthis option.) To switch between modes, do the following: To change from the GUI login to the command-line login, open a terminalwindow and type (as root) init 3. To change from the command line login to the GUI login, type (as root) init 5. I Want to Change Screen Resolutions Do you want or need to swap between resolutions in the GUI on the fly? Sup- pose that you want to use 1,024 x 768, but you work on Web pages and want tobe able to see how they look in a browser at 800 x 600 or even 640 x 480. Yourmachine is very likely already set up to do this, but you just need to know how! If your machine is set up for it, you can change resolutions by pressing thekey combination Ctrl+Alt+Plus, where Plus is the big plus (+) sign on yournumber pad you can t use the plus sign on the main keyboard for this one. 376Part V:The Part of Tens
