middle mouse button not working after feisty upgrade

[tictactatic]

I have successfully upgraded via the dist-upgrade tool (followed the wizard from Adept) to Feisty. One unpleasant surprise has been that the middle mouse on my run-of the-mill Genius USB optical mouse is no longer working. I tried fiddling with some xorg.conf settings, but nothing really seems to be helping.

The relevant section in xorg.conf is:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
option "CorePointer"
option "Device" "/dev/input/mice"
option "Protocol" "ExplorerPS/2"
option "ZAxisMapping" "4 5"
option "Emulate3Buttons" "false"

Does anybody have any ideas what could be happening?

option "Emulate3Buttons" "false"

Try setting this to "true", I'm guessing that should solve it.

Yeah, usually that's enabled by default. Don't know why it isn't.

Actually, I had changed the value to "false". When it is "true" it does what it is supposed to do, it emulates the third button by a simultaneous click on the left and right buttons.

So regardless, whichever way I have this value set, the third button doesn't work. It could be just a quirk of this particular old USB mouse I have. I just tried one of these portable mice, also from Genius, and the middle click works fine. Go figure.

I wish I could understand better how mouse config works (cause the damn thing is a run of the mill USB wheel mouse, btw. scroll works), but mice being as cheap as they are...

In any case, thanks for your help.

Just another one of my silly ideas: try a different protocol, as for example IMPS/2 (instead of "ExplorerPS/2").

May not be so silly. I agree.

Re: middle mouse button not working after feisty upgrade

I happened across a post about people configuring multibutton mice (those 5+ ones) and they add the line

Option “Buttons” “7″

to the mouse entry in their /etc/X11/xorg.conf file, might be worth giving that a try? I know you don't have 7 buttons, but still.

That might work as well. Just set it to the number of possible inputs your mouse can do (other than moving), i.e. three buttons, plus two for a wheel, plus one for clicking the wheel.

I just had a thought--my mouse has two buttons under the wheel. I wonder what they'll do.
