..drop the "quiet" part until you have fixed this issue,
you also might try "verbose" and "debug" for even more
error and warning messages.  

..can also be done on a per boot basis; on boot-up, simply
hit "e" to edit "quiet" out of the boot command line, 
then just boot to see them thar non-quiet messages.

  Scenarios always come in sets of three: 
  best case, worst case, and just in case.

A web search suggests that the following will compensate for the hardware 
issues you are experiencing
I do not have your hardware and therefore cannot test.

edit /etc/default/grub and add parameters for i8042

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i8042.nomux"

then run
$ sudo update-grub
and reboot

When done correctly they will show on the kernel command line
$cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-?.??. root=/dev/ ro quiet splash i8042.notimeout 
i8042.nomux

The script is here:

Are we talking about the same script, Riccardo?

Cheers,

I found out at least why this happens. The EFI BIOS has a setting for "USB 
Legacy mode" for the pointing device. If I enable it, the touchpad disappears, 
if I enable it shows.
However,  neither enabled nor disabled the touchpad works!
I would assume that in compatibilty mode maybe it shoudl somehow work as a 
simple mouse?

With compatibility mode, this is reported by xinput:

$ xinput

And Steve's script does:
sh touchtoggle.sh 
diagnostic devid =13
diagnostic scratchline=Device Enabled (175): 1
diagnostic proptext =Device Enabled#
diagnostic propid =175
Current state of 1 has been changed to 0.

and it always says 1->0 even if you rerun it.

More ideas?

Re: [DNG] fresh install of chimaera on an Ultrabook - no touchpad

[Riccardo Mottola via Dng]

Hi,

Can  I ask you back to my oiriginal issue? Installation media issues were 
worked around anyway.
Using chimarera I updated in the meanwhile, kernel, etc. but I still have no 
working touchpad, a hassle on a small Ultrabook the goal of which is to be 
portable.

I wonder if the issue is at kernel-level or at Xorg-level

I am worried that I continue to see in the kernel messages this:
[ 3259.860388] psmouse serio1: bad data from KBC - timeout
[ 3259.862378] psmouse serio1: bad data from KBC - timeout
[ 3259.864383] psmouse serio1: bad data from KBC - timeout
[ 3259.866390] psmouse serio1: bad data from KBC - timeout
[ 3259.868340] psmouse serio1: bad data from KBC - timeout

psmouse could well be my touchpad, no?

Somebody off-list sent me a script by Steve Litt, which I did run and does not 
help, giving this output:

diagnostic devid =
diagnostic scratchline=Device Enabled (175): 1
diagnostic proptext =Device Enabled#
diagnostic propid =175
Current state of 1 has been changed to 0.

  [ ...]
Usage: xinput set-prop  [--type=atom|float|int] [--format=8|16|32]

no devid is found!

⎜   ↳ Virtual core XTEST pointerid=4[slave  pointer  (2)]

I swear there was a touchpad, now it is totally gone ! I am puzzled.


I am using libinput for xorg, since synaptics when installed has no cursor 
working at all, not even the external mouse :)

However I noticed checking the XFCE mouse panel
