mouse and keyboard problems under RHEL 5 with multi-core host


I use RHEL 5 with a multi-core (single cpu, 4 cores, Intel Xeon) host (MEM 4G). However, I found that mouse and keyboard always lost respond when I used them in GNOME. The mouse periodically stops at some position and then moves. The keyboard input sometimes displays very slowly. It looks like the linux system is running on a old pc... I don't know why all this happens? Hope someone can help me with some suggestions or hints, thanks a lot!

Are you using PS/2 or USB mouse and keyboard?

If you are using USB mouse and keyboard, what is the output of "lsusb -v" and "lsbusb -vv". I may have the syntax wrong. Double check me by running "lsusb --help".

What kernel are you running? Have you tried upgrading to a newer kernel? Are you trying to run a 32-bit kernel on 64-bit hardware? Are you trying to run a non-SMP kernel on SMP hardware?

The answers to these questions will help us to help you.

I don't know if it has something to do with the driver of display card.

I use lspci and find that the video card is XGI but now the driver in xorg.conf is "sis". If it causes the problem?

Can you post the output of "lspci -vv" and "lspci" here?
