Well, I've changed gpm -m /dev/psaux -t ps2 -Rms3 to gpm -m /dev/psaux -t autops2 -Rraw > In either case, you then change the X configuration back to IMPS/2 > and set the ZAxisMapping and Emulate3Buttons lines as suggested > before, which will then correctly recognize the scroll wheel because > it's getting the raw data from the mouse, including the scroll wheel > events. And here comes the funniest part: either I set the protocol to "NetMousePS/2" or "IMPS/2", the wheel now works... ONLY FORWARDS !! I mean, the scroll works as sliding down the scrollbar, not as sliding up. After spending (investing?) the whole evening trying to hack this (and some audio issues and a little perl script), I consider my hacking day finished. Now it's time for a beer, perhaps tomorrow I'll have more luck.
