Everything I have googled and read talks about scrolling using the middle button, but I just want it to open a link in a new tab when I middle-click in firefox.
It worked fine in Slackware 11 before so I am guessing I have screwed up somewhere. I have fiddled with my Xorg.conf a lot but nothing seems to get the middle button (the one under the space bar) working.
I can right and left click from the trackpoint buttons, I can tap on the trackpad to generate a left click and right-click clicking the trackpad button generates a right click also.
Just to make sure it was not a hardware problem or dirt under the keyboard I booted from a live CD and the functionality worked as expected.
Here is the mouse section of my /etc/X11/xorg.conf:
# Indentifier and Driver
Option "Protocol" "imps/2" #PS/2 Mouse
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5 6 7"
Many, many thanks in advance for any pointers as to what I am missing.
