My first suggestion is to try either 2.2-BETA or 3.0-970118-SNAP. (SNAP is better as far as keyboard access code is concerned.) They use entirely new keyboard I/O routines, and the new routines are expected to work better than the ones which they replace... well, in theory :-) However, if your Compaq luggable has a really unusual keyboard and a keyboard controller, even they may not work though ;-< Commenting keyboard reset code out may or may not work; I really don't know. The purpose of keyboard reset is to detect the keyboard, initialize it and place it in the known state, AFAIU. Kazu
