[FUJITSU FMVS90TB] SynPS/2 Synaptics TouchPad detected, but not working at all

[Nobuto Murata]

SynPS/2 Synaptics TouchPad is detected, but not working at all. I disabled touchscreen from BIOS level, but still no luck.

$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=9 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]

    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ FJ Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

WORKAROUND:
1. write "/etc/default/grub.d/touchpad.cfg" as follows
====
# workaround for LP: #1500504
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT i8042.nomux"
====
2. execute `sudo update-grub` and reboot

To be clear, the touchpad is not broken. It works on Windows.

[Nobuto Murata (nobuto)]

For the record, I tried mainline build below, but I still don't see any event from touchpad.
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-rc3-unstable/

"i8042.nomux" does the trick. I've got the kernel parameter from here:
https://bugzilla.kernel.org/show_bug.cgi?id=69731

Will test it more to confirm it really fixes my problem.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Mark (1aunchpad-nct)]

I have this exact problem (same xinput and evtest results) on the same model hardware. The touchpad does not work in Tails either.

I am running Trusty, updated as of 2 hours ago.

Re comment #5, did it really fix your problem and did you only need i8042.nomux or did you need notimeout as well?

In my searches about this problem I found a message from 2009 about fixing a problem with the Intel 8042 controller and touchpads not working after "thaw/resume" which presciently said

| This HOWTO will NOT help you IF:
| Your touchpad and/or keyboard do not work at all after a fresh boot.
| In this case you probably have a problem related to i8042 but NOT this one. There are people around who
| have ideas on workarounding that.

A mere 6 years on and still not fixed!!!!!

[Nobuto Murata (nobuto)]

@Mark (1aunchpad-nct),

For my case(FUJITSU FMVS90TB), only i8042.nomux was needed. I have no problem with suspend/resume.

[Mark (1aunchpad-nct)]

@nobuto, i8042.nomux worked for me too. Not surprising as I have the same model (FMVS90TB). Thank you so much for figuring out a solution and posting it here. You likely saved me many hours of my life.

I just hope I remember about this in the event the change to grub gets overwritten in some future update. Hope they fix the kernel soon.

[Nobuto Murata (nobuto)]

@Mark,
Although I or someone needs to report and fix it in the kernel, for the time being you can write the file as follows to make sure to add "i8042.nomux" for every kernel update.

[/etc/default/grub.d/touchpad.cfg]
# workaround for LP: #1500504
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT i8042.nomux"

 `sudo update-grub` needs to be executed by hand for the first time. But update-grub will be triggered automatically for the next kernel update.

Thanks,

[Mark (1aunchpad-nct)]

@Nobuto
I'll do what you suggest. Thanks.

[Amby Chy (mynameisambychi)]
