Yes, this is a PowerBook 6,1 Model A1010/1931, or M8760LL/A if you prefer. PowerPC 7455 processor with the NVIDIA GeForce4 420 Go video card. I already had to struggle with the rubbish Nvidia graphics, and created a /usr/local/etc/X11/xorg.conf.d/driver-nvidia.conf just to get X11 visible. >> I've managed to get X working with a window manager and file manager for a >> minimal desktop but I cannot get the touchpad to work in X at all. >> >> I first tried loading the wsp(4) driver as a module in /boot/loader.conf, >> then tried the older atp(4) separately, but the device isn't binding to >> /dev/atp0. > > These are for trackpads connected over internal USB, which were only on later PowerBook G4s and newer machines. Given the specs you listed I think it's likely that yours is one of the older ones that predate this type of touchpad Ah, yes. It is certainly an ADB touchpad. Leading to the next question... >> dmesg says: >> >> ams0: <ADB Mouse> at device 3 on adb0 >> ams0: ADB Mouse = 0xd (Extended Mode) >> ams0: 2-button 400-dpi Touchpad > > This is an ADB attachment, not a USB attachment. This implies that that your touchpad is at /dev/ams0. I thought so, too. After removing moused_port=“/dev/atp0” and reverting to default, I see the touchpad is at /dev/ams0 but not doing anything. I’ve rebuilt the kernel to ensure the old adb driver is present. Xorg.0.log tells me: [ 48.939] (II) config/udev: Adding input device System mouse (/dev/input/event0) [ 48.940] (**) System mouse: Applying InputClass "libinput pointer catchall" [ 48.940] (II) LoadModule: "libinput" [ 48.943] (II) Loading /usr/local/lib/xorg/modules/input/libinput_drv.so [ 49.943] (II) Module libinput: vendor="X.Org Foundation" [ 49.943] compiled for 1.20.9, module version = 0.30.0 [ 49.943] Module class: X.Org XInput Driver [ 49.943] ABI class: X.Org XInput driver, version 24.1 [ 49.944] (II) Using input driver 'libinput' for 'System mouse' [ 49.944] (**) System mouse: always reports core events [ 49.944] (**) Option "Device" "/dev/input/event0" [ 49.946] (**) Option "_source" "server/udev" [ 50.105] (II) event0 - System mouse: is tagged by udev as: Mouse [ 50.109] (II) event0 - System mouse: device is a pointer [ 50.113] (II) event0 - System mouse: device removed [ 50.117] (**) Option "config_info" "udev:/dev/input/event0" [ 50.118] (II) XINPUT: Adding extended input device "System mouse" (type: MOUSE, id 6) [ 50.122] (**) Option "AccelerationScheme" "none" [ 50.122] (**) System mouse: (accel) selected scheme none/0 [ 50.122] (**) System mouse: (accel) acceleration factor: 2.000 [ 50.122] (**) System mouse: (accel) acceleration threshold: 4 [ 50.136] (II) event0 - System mouse: is tagged by udev as: Mouse [ 50.139] (II) event0 - System mouse: device is a pointer But still no mouse activity. Then I added a simple mouse.conf to /usr/local/etc/X11/xorg.conf.d using libinput as the driver, but that simply gave me a black screen. I tried it again with the advice from Ch 11 of the FreeBSD FAQ. > Section "InputDevice" > Identifier "Mouse0” > Driver "adb" > Option "Protocol" "SysMouse" > Option "Device" "/dev/sysmouse” > EndSection But still nothing. Where should I look for the next step? Something in sysctl.conf? —Omar > Brandon Bergren > bdragon@FreeBSD.org >help
