Dear Linux experts there,

I recently installed RedHat Linux 7.2 and I constantly got X-window frozen. The system seemed to lose contact with keyboard and mouse. Even the light on keyboard is gone. So the system looks like running without keyboard and mouse.

Any explanation and fix for this urgent problem. I also run W2K and never have this problem.

Please email me any of your advice to:

Are they usb?

Mouse is Logitech OEM MouseMan PS/2 mouse, Keyboard is normal one.

does ctrl+alt+backspace do anything when it's locked?

I tried to turn on CapsLock and Num Lock and Scroll Lock on the keyboard, but nothing happened. It seemed the mouse and keyboard were disconnected from the computer system which I have never seen under Windows.

I never saw it in linux either, unless it was locked up.

have you tried a different window manager?

Probably I should try. I am using swarmfish(?), the other one can be used is tvm(?).

I should clear it out that I could work on this puppy either for a few minutes to an hour. But it could be got frozen on anther app.

My computer is P4 1.5GHz, with 512M RAM, 40 GB disk AOpen mother board and V card.

Do a search in the /etc/X11/XF86Config-4 for "InputDevice" and post all the text that's between Section and EndSection. You should at least have an entry in the "ServerLayout" section and a couple of "InputDevice" sections (one for keyboard and one for mouse).
