I am on a Dell XT
After using Rik's method with dmesg, I added the following line to alps.c:
{ { 0x73, 0x00, 0x14 }, 0xcf, 0xcf, ALPS_PASS | ALPS_DUALPOINT |
ALPS_PS2_INTERLEAVED }, /* Dell Latitude XT */
as result:
- lsinput recognizes the alps touchpad and the dualpoint stick:
/dev/input/event10
bustype : BUS_I8042
vendor : 0x2
product : 0x8
version : 0
name : "DualPoint Stick"
phys : "isa0060/serio1/input1"
bits ev : EV_SYN EV_KEY EV_REL
/dev/input/event11
bustype : BUS_I8042
vendor : 0x2
product : 0x8
version : 29442
name : "AlpsPS/2 ALPS DualPoint TouchPad"
phys : "isa0060/serio1/input0"
bits ev : EV_SYN EV_KEY EV_ABS
- scrolling does not work on the touchpad
- pointing stick and related buttons do not work
- "sudo input-events 10" shows data only when using the touchpad (not the
pointing stick):
01:42:48.036377: EV_REL REL_X 1
01:42:48.036384: EV_SYN code=0 value=0
- input-events 11 does not show any data
If I change the line and eliminate ALPS_PASS as in:
{ { 0x73, 0x00, 0x14 }, 0xcf, 0xcf, ALPS_DUALPOINT |
ALPS_PS2_INTERLEAVED }, /* Dell Latitude XT */
- the devices are still recognized as before
- scrolling works on the touchpad
- the pointing stick behavez strange, with the cursor jumping and clicking
randomly
- pointing stick buttons do not works
- "sudo input-events 10" shows data only when using the pointing stick (not the
touchpad, although the touchpad works very well):
01:46:11.234481: EV_REL REL_X -380
01:46:11.234488: EV_REL REL_Y -255
01:46:11.234490: EV_KEY BTN_LEFT (0x110) pressed
01:46:11.234492: EV_KEY BTN_RIGHT (0x111) pressed
01:46:11.234497: EV_KEY BTN_MIDDLE (0x112) pressed
01:46:11.234501: EV_SYN code=0 value=0
- "sudo input-events 11" does not show any data
