I compiled kernel 2.6.6 on my VAIO laptop running Slackware 9.1 yesterday, and am very happy with it - except that my Samsung optical scrollmouse doesn't work - an attempt to move it will send the cursor flying around the edges of the screen and cause various click events, entertainingly opening menus and kicking off random applications and configuration options!
Now, this is the first time I've tried a 2.6 kernel with this mouse, but it was working fine under 2.4 with the following setup in XF86Config:
Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse"
Option "ZAxisMapping" "4 5"
After searching this site and a few others, I've tried a few things, including adding append="psmouse_noext=1"
and / or append="psmouse_resolution=200"
to lilo.conf (and rebooting after running lilo of course) - all to no effect.
Interestingly, after booting up with a standard three button ball mouse plugged in then replacing it with the optical scrollwheel mouse, the optical mouse works basically fine, (except that the scrollwheel doesn't work)!
I guess there must be something fundamentally different about the mouse config in 2.6.
Thanks in advance,
