If you are experiencing difficulties when trying to IPL from *NWSSTG, you may not have created a PReP Boot partition set as active.
This information does not apply to users of iSeries systems.
If you have installed the X Window System but are not seeing a graphical desktop environment once you log into your Red Hat Enterprise Linux system, you can start the X Window System graphical interface using the command startx.
Once you enter this command and press
Note, however, that this is just a one-time fix and does not change the log in process for future log ins.
To set up your system so that you can log in at a graphical login screen, you must edit one file, /etc/inittab, by changing just one number in the runlevel section. When you are finished, reboot the computer. The next time you log in, you will have a graphical login prompt.
Open a shell prompt. If you are in your user account, become root by typing the su command.
Now, type gedit /etc/inittab to edit the file with gedit. The file /etc/inittab will open. Within the first screen, a section of the file which looks like the following appears:
# Default runlevel. The runlevels used by RHS are: # 0 - halt (Do NOT set initdefault to this) # 1 - Single user mode # 2 - Multiuser, without NFS (The same as 3, if you do not have networking) # 3 - Full multiuser mode # 4 - unused # 5 - X11 # 6 - reboot (Do NOT set initdefault to this) # id:3:initdefault: |
To change from a console to a graphical login, you should change the number in the line id:3:initdefault: from a 3 to a 5.

Change only the number of the default runlevel from 3 to 5. |
Your changed line should look like the following:
id:5:initdefault: |
When you are satisfied with your change, save and exit the file using

Now, your next login after reboot will be from the graphical screen.
If you are having trouble getting X (the X Window System) to start, you may not have installed it during your installation.
If you want X, you can either install the packages from the Red Hat Enterprise Linux CD-ROMs or perform an upgrade.
If you elect to upgrade, select the X Window System packages, and choose GNOME, KDE, or both, during the upgrade package selection process.
If you did not create a user account in the Setup Agent, log in as root and use the password you assigned to root.
If you cannot remember your root password, boot your system as linux single.
Once you have booted into single user mode and have access to the # prompt, you must type passwd root, which allows you to enter a new password for root. At this point you can type shutdown -r now to reboot the system with the new root password.
If you cannot remember your user account password, you must become root. To become root, type su - and enter your root password when prompted. Then, type passwd <username>. This allows you to enter a new password for the specified user account.
If the graphical login screen does not appear, check your hardware for compatibility issues. The Hardware Compatibility List can be found at:

If you are not sure how to set up your printer or are having trouble getting it to work properly, try using the Printer Configuration Tool.
Type the redhat-config-printer command at a shell prompt to launch the Printer Configuration Tool. If you are not root, it prompts you for the root password to continue.
