Appendix D. Troubleshooting Your Installation of Red Hat Linux

D.4.7. Your Printer Will Not Work

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 in a shell prompt to launch the Printer Configura 

tion Tool. If you are not root, it will prompt you for the root password to continue.

D.4.8. Problems with Sound Configuration

If you do not have sound after your installation, you may need to run one of the sound configuration

utilities.

To run the graphical sound configuration tool (Red Hat Sound Card Configuration Tool  

redhat config soundcard

), from the Main Menu click on System Tools=>Sound Card

Configuration.

To run the text based configuration tool, as root, type

sndconfig

in a terminal window.

Note

sndconfig must be run in runlevel 3. More information about runlevels can be found in the Official

Red Hat Linux Reference Guide, in chapter Boot Process, Init, and Shutdown.

If the sound card configuration tools do not help, you may need to select the

Enable sound server

startup

option under Multimedia=>Sound in the GNOME Control Center.

To do this, click on Panel=>Programs=>Settings=>GNOME Control Center to launch the

GNOME Control Center. In the GNOME Control Center, select the Sound submenu of the

Multimedia menu. On the right, a General sound menu will appear. Select

server startup
