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?

frznchckn 02-26-2011 05:24 PM

We can assume that.

corp769 02-26-2011 05:28 PM

Ok, that works.

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

Code:

ls -al /dev/input/mouse*

frznchckn 02-26-2011 05:32 PM

/dev/input/mouse0

corp769 02-26-2011 06:01 PM

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.

frznchckn 02-26-2011 06:53 PM

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!

corp769 02-26-2011 07:01 PM

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
