Touchpad randomly stops moving (clicks still work) on Hyprland

5hridhyan · Yesterday 13:43:30

It's not the first time, but its getting annoying lately
Touchpad (the cursor) stops working randomly; The fact is keyboard works normally, and clicking button also works, I don't remember if taps work; no gestures, no movement.
"affected" journal: https://paste.c-net.org/AbruptDolphins although I couldn't find anything wrong

I'm on Hyprland, and I don't remember experiencing this when I was using KDE or Gnome

sometimes just opening Kitty(terminal) solves the issue, or running hyprctl reload solves the issue, or sometimes I have to log out and log in
it's not reproducible, sometimes w/o doing anything it just gets working
on the journal there are TLP spam, I disabled it while trying to solve a previous issue; however I now uninstalled it. The behavior was before I setup TLP or AutoCPU-Freq.

So my question is: How do I make my touchpad "more" reliable on Hyprland? I hate this inconsistency

I sometimes encounter similar issue on Dell Latitude 5400, also touchpad on I²C bus:

N: Name="DELL08B8:00 0488:121F Touchpad"
P: Phys=i2c-DELL08B8:00
S: Sysfs=/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-1/i2c-DELL08B8:00/0018:0488:121F.0001/input/input15

Sometimes cursor starts to slow down for few seconds before becoming completely unresposive.
However, I don't use Hyprland, in my case neither Xorg restart or logout/login doesn't help, only reboot recovers it. The same behavior observed in VT with gpm as well.
Perhaps in your case it recovers because of some kind of reinitialization.
I'm pretty sure it's a hardware of firmware bug. Sometimes I can reproduce it by placing AC adapter wire close to another noisy power supply unit. Haven't found solution yet.

There're unfortunately no timestamps in the hyprland log - does the touchpad still generate the expected input in "libinput debug-events" or "evtest"?
There's an occasional "palm detected (edge)", can you reproduce this when doing some trap/delt/bicep training and lifting your paws so they won't touch the pad for sure?

@dimich, Yes I remember I rebooted once because of this issue, but it was like 1 in a 100000th time...
@seth I really tried hard to reproduce and test w/ libinput, I'm still not being able to reproduce it
I suspect my Keyboard is contributing it, my keyboard "has" a history of Ghost inputs, like if pressed and released a key, the key still keeps inputting on the screen; again this is also not reproducible, Im suspecting it because I have `disable_while_typing = true`, but I don't know how will it explain using other keybinds to open terminal or run commands
also I remember my palms paws were at my textbook
although I'm like a lazy cat, my paws are almost always lying on it, but at the time, my paws weren't resting I was trying to move the cursor

When it happens again I'll run libinput or evtest, and bump this thread w/ relevant output and observations(if any)
