touchpad on dell laptops
« on: April 23, 2015, 11:02:09 AM »
Hi,
i have upgraded from version 5.x to 6.1. Now the touchpad's won't work. With the 5.x-Version no problem. Tested several different dell laptops (also different models) - always the same :-(

Are you using Xvesa, Xfbdev or Xorg-7.7?

I have tried Tiny Core and CorePlus on many sub-versions from 2 through 6.2 on laptops from D410s to E64xx (I'm trying to get suspend to work to make TC my Secure Erase solution).  The touchpad has worked in every version so far.

I using that setting : xvesa=1366x768x32
But i did use it for 5.x-Version too.

This is the full config line:
 append initrd=/ubninit loglevel=3 showapps desktop=flwm_topside kmap=qwertz/de-latin1 tz=CET-1 waitusb=5 host=tiny xvesa=1366x768x32

That does not mean you are using Xvesa.
What are the contents of onboot.lst?

I can duplicate the same behaviour on a dell laptop.

Ref
Code: [Select]
$ cat ~/.xsession
Xvesa -br -screen 1024x768x32 -shadow -2button -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &

and:
Code: [Select]
$ cat /proc/bus/input/devices
...
I: Bus=0011 Vendor=0002 Product=0008 Version=0300
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input6

.. I used to be able to change the input to input6 (for example) and it would use only the touchpad and not the mouse, but this also doesn't appear to work.

This being said "mice" is meant to be a catchall.

If you cat both of them, and touch the pad, do you get output?

cat /dev/input/mice # wiggle, ctrl-C
cat /dev/input/event6 # same

@olihd - in the meantime you can use Xorg-7.7 with xf86-input-synaptics

Then it is the kernel's issue, not X's.

Ah - I should have read down further:
Code: [Select]
$ cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0008 Version=0300
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input6
U: Uniq=
H: Handlers=mouse2 event10

i.e. not /dev/input/input6, but /dev/input/event10

There is touchpad input on /dev/input/event10, but not on /dev/input/mice

And if you tell Xvesa/fbdev to use /dev/input/mouse2?

There's nothing on "cat /dev/input/mouse2", but I confirm there's a connection to /dev/input/event10

Ok, a kernel bug then. As you have the hw, either you or OP might want to try to find out what kernel version introduced it and file a bug.
