First of all, wmii was totally busted as it wouldn't respond to any commands involving my mod key (which is alt). I noticed (using xev) that shift+alt did not register properly, so of course wmii wouldn't respond. Here's the fix (don't ask me what it means):
setxkbmap -symbols 'pc+us+inet(evdev)+level3(ralt_switch)+ctrl(swapcaps)+compose(lwin)'
Then I discovered that I couldn't use the middle mouse button to scroll with the trackpoint. Since the xorg.conf file has mostly gone the way of the dodo, here are the magic xinput commands to get that working:
xinput set-int-prop 'TPPS/2 IBM TrackPoint' 'Evdev Wheel Emulation' 8 1 xinput set-int-prop 'TPPS/2 IBM TrackPoint' 'Evdev Wheel Emulation Button' 8 2 xinput set-int-prop 'TPPS/2 IBM TrackPoint' 'Evdev Wheel Emulation Timeout' 8 200 xinput set-int-prop 'TPPS/2 IBM TrackPoint' 'Evdev Wheel Emulation Axes' 8 6 7 4 5
Now, I just take all that stuff and jam it into my xinitrc, then I never think about what any of it means and use wmii happily.
Of course, I still had to build the fglrx kernel modules and modify the xorg.conf to make the video card sing:
Section "Device" Identifier "Radeon 3200 HD" Driver "fglrx" BusID "PCI:1:5:0" Option "VideoOverlay" "on" Option "OpenGLOverlay" "off" EndSection Section "Screen" Identifier "Thinkpad Screen" Monitor "Thinkpad LCD" DefaultDepth 24 EndSection Section "Monitor" Identifier "Thinkpad LCD" Option "DPMS" EndSection Section "ServerLayout" Identifier "Thinkpad Layout" Screen "Thinkpad Screen" Option "AIGLX" "true" EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "enable" EndSection
Critical result: HAPPY!
