Linux change the monitor or video card settings

Posted on in Categories last updated April 22, 2006

Q. I am new to Linux. While playing with Linux display setting I made few of change to monitor and video card settings and restarted the Linux computer. Now I am getting very bad display. I am not able to get back GUI tools, how do I fix this mess?

A. Linux comes with the X Configuration Tool. Sometime you play with X display and after restart it will not work or during installation you select wrong settings. Here are list of tools you can use to reset your monitor and video card display settings:

If you are using FreeBSD use following two commands:

# Xorg -configure
# XFree86 -configure

Alternatively, use sysinstall tool:

# sysinstall

If you are using Debian Linux type command:

# dpkg-reconfigure xserver-xfree86

If you are using RedHat Enterprise or Fedora Linux type command:

# redhat-config-xfree86
