Strange. Here I've got problems with my mouse being actually 'to fast' (when working with X-Window; I had to slow it down about 2 times via xset to be able to work 'normally'; Actually -since I could not find any related bugreports or complains - I thought it was something with how my version of X works with new layer) > 2.4's pc_keyb.c has (disabled by default) init code which puts the > mouse in 100 samples/s and 2:1 scaling, whereas 2.5 puts it into > 200 samples/s and 1:1 scaling. So I hacked psmouse-base.c to mimic > 2.4, and VOILA! now my mouse feels A LOT better. And here it goes even faster than before. Live is indeed full of suprises :) [cut] jk -- Jacek Kawa
