x11-base/xorg-server-1.12.4
xfce-base/xfce4-meta-4.10

I have had this problem forever (it seems). Spontaneously I get a mouse scroll event generated, and the (Microsoft Wheel Mouse Optical USB) mouse never did this back when it was my Windows gaming mouse. Any idea what to play with? I do have a minimal xorg.conf for dual monitor setup:

Code:
Section "Monitor"
   Identifier   "Benq"
EndSection

Section "Monitor"
   Identifier   "Gateway"
   Option      "RightOf" "Benq"
EndSection

Section "Device"
   Identifier   "Card"
   Driver      "radeon"
   Option      "Monitor-DVI-0"   "Benq"
   Option      "Monitor-HDMI-0" "Gateway"
EndSection


I manually run

Code:
xrandr --output HDMI-0 --right-of DVI-0


when I first (manually) start X to get the dual monitor effect I'm after. Problem occurred before I went dual-monitor.

The mouse wheel has detentes and does not feel sloppy or anything - I just out of the blue get the window under my mouse (often Cream while I'm editing code) scrolling, or the window shading because the mouse was on the title bar.. very annoying.

Any idea what to play with? I manually run startx, so stuffing an xset call or something in my .xinitrc is fine.

I once had a problem with spontaneous mouse clicks and it was hardware related.
If I remember correctly 'xev' can differentiate between hardware and software generated events by marking the latter with 'SYNTETIC' flag.
That way you can at least verify whether the problem is caused by buggy drivers.

It is really sporadic to try with xev - have not really anecdotally determined if it only occurs at the same time as key presses or not; do know that is not at the same time as mouse moves because it has often bit me while typing code into my editor.

pdr,

You could obviously get another mouse to rule out hardware fault.

I first brought this mouse from home because of this problem. It's a nicer mouse than the one the company gave me, so stuck with it.
