On occasion there's a conflict that causes gpm and the X mouse handler to fight each other. I usually have gpm disabled in run level 5: chkconfig --level 5 gpm off If I need to go to a virtual console via C-A-number and need gpm, I'll start it in the virtual console. As far as plugging/unplugging PS/2 keyboards and mice...we've done it for years on literally thousands of machines and haven't popped a mobo yet. The operative word there is "yet". It hasn't happened to us, but it could. We have, however, bent many a pin on the DIN connectors and VGA cables, so we use short pigtails between the device and the computer. Lots cheaper to replace a pigtail than the device! ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - When all else fails, try reading the instructions. - ----------------------------------------------------------------------
