due to fuzzy thinking and fumble fingers, I no longer have the version that caused the problem, so I cannot guess what the change was that caused the problem. However the Mouse configuration entries were the same between the two!!Rats! I've never had a wheel working under linux, and I was following this thread sure the solution would be revealed...
I've just subscribed. Pardon me for not having time to look up previous posts, but here is what I have in my /etc/X11/XF86Config-4 on a Debian stable: ---------------------------------------------------------------------- Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/psaux" Option "Protocol" "ImPS/2" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Generic Mouse" Driver "mouse" Option "SendCoreEvents" "true" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" Option "ZAxisMapping" "4 5" EndSection Section "ServerLayout" [...] InputDevice "Configured Mouse" InputDevice "Generic Mouse" EndSection ---------------------------------------------------------------------- I've never bothered to check if one of these entries is superfluous. Works like a charme. Mouse is a <crossing myself> M$ IntelliMouse. -- Bye, Kai
