Display settings in Red Hat

Posted on 2003-11-15
Last Modified: 2012-05-04
I have managed to install Red Hat onto my Dell Inspiron 2650 laptop. However when I configured it during instalation I set the display size at 800x600, or something like that. Now I would like to change it. I have found how to set this in motion, but then it tells me to Log out and restart the x server. My first question is does the x server start on it's own or do I have to do something cause nothing has changed ? The display is the same. Also it says that my display is undetected, does this matter or is that why nothing has changed ?  My last question is, could you please make the answer simple as you might as well ask me to fly to the moon as start up the x server?

How to change the X resolution on RedHat depends on what version you are running. On anything prior to 8.0 the correct tool would be Xconfigurator. There you'd probably want to select a single resolution and color depth. On 8.0 or later the correct tool is redhat-config-xfree86.

After changing the X configuration logging out and logging back in should make the change effective. But you can also just reboot the system.

I have found out I am running Red Hat realease 9. But I'm still not sure how to do the "red-hat-config-xfree86"

The command, entered in a terminal window, is redhat-config-xfree86. Not red-hat-config-xfree86. And you must execute is as root.
What does it mean to be "Always On"?

I checked this out, and found that is what I have been doing. I tried through the terminal but it is  still the same.  I clicked on Advenced, and it said "unprobed moniter" could that be the problem, the reason nothing is changing ?

Apparently the config tool doesn't have a table entry for your particular monitor. I'd suggest going to the Advanced section, scrolling to "Generic Monitor" and picking one that is close to what your display is capable of.
