I have been trying unsuccessfully to switch the left and right mouse buttons on a Logitach V270 bluetooth mouse working with a Samsung Q35 laptop, in Fedora Core 5 with a KDE desktop. (kernel 2.6.15-1.2054_FC5smp). First attempt was to go to the KDE control centre and then to Peripherals -> mouse, and then switch to left handed. This changed the touchpad over to left handed but not the blueooth mouse. Second attempt at something more involved was to open a terminal, and type xev. In the window that opened I moved the cursor into the box and clicked the left and right mouse buttons to confirm that they represented button events 1 and 3 which they did. Indeed I also hit the left and right touchpad buttons to also get 1 and 3 shown in the xev window. I hoped that I could swap these for both mouse and touchpad in one fell swoop. So I did xmodmap -pp, and this showed that there were 12 button events defined. So I did xmodmap -e "pointer = 3 2 1 4 5 6 7 8 9 10 11 12" xmodmap -pp confirmed that the order was switched between 1 and 3 - and the touchpad had indeed swapped over to left-handed operation.... BUT the bluetooth mouse still produced the left button event using the left button - i.e. the effect was exactly the same as when the swap was made in the KDE control centre! I am stumped - Anyone got any possible ways I might work around this to achieve the objective? Or has anyone got a link to some information about the options in the new xorg ? I believe that there is a new option available in the xorg.conf for the mouse section of the form: Option "Buttons" "1 2 3 4 5 6 7" etc. Any help appreciated - Mike -- mike cohler
