touchpad freezing on system76 gazelle

I have a system76 gazelle and I have noticed that my touchpad occasionally freezes. I am seeing these in dmesg

I have looked around the forums and some have suggested add kernel parameters in grub. Here are mine. Has anyone ran into this and found a decent solution

GRUB_CMDLINE_LINUX_DEFAULT="quiet i8042.noloop i8042.nomux i8042.nopnp i8042.reset"

Re: touchpad freezing on system76 gazelle

Are you using the synaptics driver? Why?

Moving to NC...

Re: touchpad freezing on system76 gazelle

Is it wired via USB?
Hit by USB autosuspend?

Re: touchpad freezing on system76 gazelle

I am not sure if the touchpad is seen as a USB device or not.

Re: touchpad freezing on system76 gazelle

Ask the system?

lsusb
lspci

And in doubt (if nothing sticks out being named "touchpad" or so)

lsusb -vv
lspci -vv

See https://wiki.archlinux.org/index.php/Po … utosuspend

The touchpad is not coming on either command. Here is lsusb output

Re: touchpad freezing on system76 gazelle

So I have tried turing off auto suspend on both USB hubs, one at a time, hoping that the Touchpad is attached to on of them. However the freezing presists.

Re: touchpad freezing on system76 gazelle

lsmod | grep i8k
ps aux | grep i8k

Do you have i8kutils installed?

Re: touchpad freezing on system76 gazelle

No I do not have them installed. I see in the aur that they are for Dell laptops. Would they also for a System76 laptop that are Celvo models?

Re: touchpad freezing on system76 gazelle

Actually, the module seems prone to cause touchpad hiccups when polling sensor data - i thought system76 might relabel various other models and sell them as linux devices.
Anyway, sensors on the same bus might still be a hook - do you have lmsensors installed and poll them with anything? What does lsmod look like anyway?

Re: touchpad freezing on system76 gazelle

The touchpad is likely handled by i2c_i801 - it knows one parameter: disable_features

modinfo i2c_i801 | tail

I'd try 0x10 or 0x11 - but that's really a wild guess.

Use the kernel commandline editor in grub in case those parameters render your system unusable (this way a simple reboot will clear the stage)

Re: touchpad freezing on system76 gazelle

I've a Clevo W230SS (sometimes System76 are rebraned Clevo), in my case the touchpad is a PS/2 touchpad, probably connected to the south bridge via serial bus. It appears using:

Re: touchpad freezing on system76 gazelle

That's just a description of the module and the possible parameters. To check the actual settings you'd ask "systool -vm i2c_i801".
Synaptics chains smbus and ps/2 - it's not really visible which bus is actually used in the end.

Depending on the "freeze" you might just have false positives of the typing condition detection,

xinput list-props "SynPS/2 Synaptics TouchPad"

Look out for the resp. property and then

xinput set-prop "SynPS/2 Synaptics TouchPad" <property> <value>

where "<value>" will likely be 0

Re: touchpad freezing on system76 gazelle

May the freezes be caused by a bad configured touchpad auto-disable feature? From the command I gave you, I see:

Disable-w-typing: enabled

When I've started using my Clevo it had a 2 seconds disable timeout and it was triggered only when using keyboard without touching touchpad. My English is too bad to express this, but the result was that auto-disable was unpredictable and it looked like touchpad was freezing instead of being disabled, infact various time I could type and move touchpad together.

Re: touchpad freezing on system76 gazelle

you mean like

libinput Disable While Typing Enabled (290):	1

?
No, can't see either :-P

xinput set-prop "SynPS/2 Synaptics TouchPad" "Disable While Typing Enabled" 0
# or
xinput set-prop "SynPS/2 Synaptics TouchPad" 290 0

Though I especially meant whether the problem happens on Xorg at all.

Re: touchpad freezing on system76 gazelle

Ie. hardware, kernel or libinput bug.
=> Try the evdev or synaptics driver (on Xorg only) to rule out libinput.

Re: touchpad freezing on system76 gazelle

Sadly there is this in GNOME Page on the wiki

Note: The synaptics driver is not supported by GNOME. Instead, you should use libinput.

Here is the bug report referenced. They pretty much say GNOME no longer supports the synaptics driver

I can verify this is still true. When I first installed arch the trackpad was not working properly. I found out b/c I had synaptics installed.
