1. | You want to upgrade the video card in your Linux system. Your old video card is slow and doesn't have enough display memory to provide you with the resolution and color depth you require. You have obtained a new ATI 32MB Radeon card (I'm using this product for example purposes only). What steps might you follow to replace your old card with your new card? | |

2. | You want to see what happens when there are problems starting the Linux GUI. With RHEL 5, the X.org server is configured by default. The configuration of the X server is stored in the /etc/X11/xorg .conf configuration file. Before Linux starts the X server, it reads this file. To do this lab, you'll want to back up your current /etc/X11/xorg.conf file, delete a line in the file, and then reboot your computer into runlevel 5. You can restore it after the lab is complete. | |

3. | For this lab, you'll need two Linux computers connected over a network and a shared NFS directory from the local computer. You can use the same directory that you may have used in Chapter 2 to share the RHEL installation files. Start a Secure Shell connection between the two computers. Start the GUI on the local computer, and use the Secure Shell to log in remotely to the other computer. Once you log in, run the Red Hat root password program from the remote computer. Make changes to the password. When you log out and try to log back into the remote computer, you should be able to confirm that the root password on the remote computer has changed. | |
