Question X fails to load because of "No core pointer"


I installed CentOS 5 on an old Dell laptop. It booted up fine with the gui. The only thing I did was change the hostname and rebooted. Upon reboot X failed to initialize and put me at the console.

I've tried to have root reinitialize the X settings to not avail. X says it has "No core pointer". The laptop obviously has a touchpad and I have a USB mouse plugged in. I can see a highlighted box on the console move based on the USB mouse and not the touchpad.

My xorg.conf has a Section "InputDevice" for a pointing device but it's going to the touchpad which does not seem to be working anyways. How do I tell X to use the USB mouse?

Thanks

Can you post your xorg.conf? Thanks!

Before I go any further, is your USB mouse always going to be plugged in?

We can assume that.

Ok, that works.

Post the output of the following with your usb mouse plugged in:

Code:
ls -al /dev/input/mouse*

Ok, should be good enough to run
Code:
Xorg :1 -configure
Once configured, you most likely need to edit the new config to remove the touchpad device. It should be located in your root directory.

Well, the touchpad device was not in the new xorg.conf but many extra "displays" where in there. Perhaps from my failed attempts at starting X? I don't know, but I removed them except for the default 0 display and it works!

Thanks!

No problem. I was going in that direction, but I wanted to make sure everything else was fine, and the configuration was intact. I was going to tell you to remove the pointer devices in the config file next, but it looks like you beat me to it.

Cheers,

Josh
