3.3.1 PS/2 mice
In the case of a PS/2-connector mouse on an ATX motherboard, the
signal flow should be:
mouse -> /dev/psaux -> gpm -> /dev/gpmdata = /dev/mouse -> X
Here, a symlink /dev/mouse is created and is pointing to /dev/gpmdata
to make some configuration utilities happy and to make reconfiguration
easy. (E.g., if you decide not to use the gpm daemon after all, just
point the symlink /dev/mouse to /dev/psaux after getting rid of the
gpm daemon.)
This signal flow allows the keyboard and mouse to be unplugged and
reinitialized by restarting gpm upon reconnect. X will stay alive!
The protocol of the signal flow between gpm output and X input can be
implemented in either of two ways, as "ms3" (use the Microsoft
3-button serial mouse protocol) or "raw" (use the same protocol as the
mouse that is connected), and this choice dictates the choice of
protocol used in X configuration.
I will demonstrate the configuration examples using a Logitech
3-button (traditional Unix-style mouse) PS/2 mouse as an example in
the following.
If you are one of the unfortunate whose graphics card is not supported
by the new X4 and need to use the old X3 (some ATI 64 bit cards),
configure /etc/X11/X86Config instead of /etc/X11/X86Config-4 in the
following examples while installing X3 packages.
3.3.1.1 The ms3 protocol approach
/etc/gpm.conf | /etc/X11/X86Config-4
=========================+======================================
device=/dev/psaux | Section "InputDevice"
responsiveness= | Identifier "Configured Mouse"
repeat_type=ms3 | Driver "mouse"
type=autops2 | Option "CorePointer"
append="" | Option "Device" "/dev/mouse"
sample_rate= | Option "Protocol" "IntelliMouse"
| EndSection
If this approach is used, the mouse type adjustment is done only by
editing gpm.conf and X configuration stays constant. See my example
scripts.
3.3.1.2 The raw protocol approach
/etc/gpm.conf | /etc/X11/X86Config-4
=========================+======================================
device=/dev/psaux | Section "InputDevice"
responsiveness= | Identifier "Configured Mouse"
repeat_type=raw | Driver "mouse"
type=autops2 | Option "CorePointer"
append="" | Option "Device" "/dev/mouse"
sample_rate= | Option "Protocol" "MouseManPlusPS/2"
| EndSection
If this approach is used, the mouse type adjustment is done by editing
gpm.conf as well as adjusting X configuration.
3.3.1.3 How to adjust to different mice
The gpm device type autops2 is supposed to autodetect most of the PS/2
mice in the market. Unfortunately it doesn't always work and it isn't
available in pre-Woody versions. Try using ps2, or imps2 in gpm.conf
instead of autops2 for such cases. To find out the specific types of
mouse gpm knows about, type: gpm -t help. See gpm(8).
If a 2-button PS/2 mouse is used, set the X protocol to enable
Emulate3Buttons. The difference of protocol between the 2-button mouse
and the 3-button mouse is autodetected and auto-adjusted for gpm after
tapping the middle button once.
For X protocol with The raw protocol approach, Section 3.3.1.2 or
without gpm, use:
* IntelliMouse: serial port mouse (gpm repeater with "ms3")
* PS/2: PS/2 port mouse (always test this first)
* IMPS/2: any PS/2 port mice (2, 3, or scroll mice, better)
* MouseManPlusPS/2: Logitech PS/2 port mouse
* ...
See more at Mouse Support in XFree86.
A typical Microsoft scroll mouse is reported to work best with:
/etc/gpm.conf | /etc/X11/X86Config-4
=========================+======================================
device=/dev/psaux | Section "InputDevice"
responsiveness= | Identifier "Configured Mouse"
repeat_type=raw | Driver "mouse"
type=autops2 | Option "CorePointer"
append="" | Option "Device" "/dev/mouse"
sample_rate= | Option "Protocol" "IMPS/2"
| Option "Buttons" "5"
| Option "ZAxisMapping" "4 5"
| EndSection
For some recent thin Toshiba notebook PCs, activating gpm before
PCMCIA in the System-V init script may help prevent system lockup.
Weird but true.
3.3.2 USB mice
Make sure you have all required kernel functions activated through
kernel compile time configuration or modules:
* Under "Input core support":
o "Input core support" (CONFIG_INPUT, input.o),
o "Mouse support" (CONFIG_INPUT_MOUSEDEV, mousedev.o),
* Under "USB support":
o "Support for USB" (CONFIG_USB, usbcore.o),
o "Preliminary USB device filesystem" (CONFIG_USB_DEVICEFS),
o "UHCI" or "OHCI" (CONFIG_USB_UHCI || CONFIG_USB_UHCI_ALT
|| CONFIG_USB_OHCI, usb-uhci.o || uhci.o || usb-ohci.o),
o "USB Human Interface Device (full HID) support"
(CONFIG_USB_HID, hid.o), and
o "HID input layer support" (CONFIG_USB_HIDINPUT)
Here, lower case names are module names.
If you're not using devfs, create a device node /dev/input/mice with
major 13 and minor 63 as follows:
# cd /dev
# mkdir input
# mknod input/mice c 13 63
For typical scroll USB mice, configuration combinations should be:
/etc/gpm.conf | /etc/X11/X86Config-4
=========================+======================================
device=/dev/input/mice | Section "InputDevice"
responsiveness= | Identifier "Generic Mouse"
repeat_type=raw | Driver "mouse"
type=autops2 | Option "SendCoreEvents" "true"
append="" | Option "Device" "/dev/input/mice"
sample_rate= | Option "Protocol" "IMPS/2"
| Option "Buttons" "5"
| Option "ZAxisMapping" "4 5"
