Inspiron 14 5410 Erratic touchpad on Ubuntu 22.04

Hi,
exactly same problem for me with my inspiropn 5410 and ubuntu 22.04.
I noticed that 'xinput list' returned 2 mouses. Is it related ? What is this "PS/2 Generic Mouse" ?

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ELAN900C:00 04F3:2C64 id=13 [slave pointer (2)]
⎜ ↳ DELL0A89:00 27C6:0D41 Touchpad id=16 [slave pointer (2)]
⎜ ↳ DELL0A89:00 27C6:0D41 Mouse id=15 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=22 [slave pointer (2)]

in any case this problem is very annoying

I have the same problem with my Dell Latitude 5431 and I have encountered a problem with the touchpad, which is replicated in Ubuntu 20.04 and 22.04 LTS versions, both in Wayland and X11. The touchpad gestures stop working and the cursor freezes in a corner of the screen.

In X11, I have been able to reconnect the touchpad gestures using "xinput disable " and "xinput enable " or by logging out of the system. The system has dell-om and focal-dell repositories, and the BIOS is updated to the January 2023 version.

Device: VEN_0488:00 0488:1040 Touchpad Kernel: /dev/input/event10 Group: 6 Seat: seat0, default Size: 109x63mm Capabilities: pointer gesture Tap-to-click: disabled Tap-and-drag: enabled Tap drag lock: disabled Left-handed: disabled Nat.scrolling: disabled Middle emulation: disabled Calibration: n/a Scroll methods: *two-finger edge Click methods: *button-areas clickfinger Disable-w-typing: enabled Accel profiles: none

I have the same issue. For me it seems worst on xorg than on Wayland. 
 Sometimes it randomly just scrolls when I move my finger over the trackpad.

I have the Delll Inspiron 5515
Ubuntu 22.0.4.2
Gnome Version

Could you private message us the Service Tag, so we can look into this for you right away? You could refer to the below link to find the Service Tag: https://dell.to/41gVd0c

@DELL-Cares​ can you share any fix for this?

I had to set a keyboard shortcut so that pressing Ctrl+Esc I get this command executed:

/usr/bin/xinput disable 'VEN_0488:00 0488:1040 Touchpad'; /usr/bin/xinput enable 'VEN_0488:00 0488:1040 Touchpad'

and this fixes the issue for a while...

BTW, I'm running Fedora 36 on a Latitude 7430

I am having this exact same issue on my XPS-15 9510 running Ubuntu 22.04 and it is a year later than these posts.  Has anyone come up with a solution?

I just tried both Zorin and Mint on an Inspiron 15 5567 -- in my case both the trackpad and wifi die at the same time. On Zorin when it happens the fan goes nuts; on Mint the same problem occurs without the fan spinning up to insane levels.

I came across something suggesting that maybe modifying /etc/grub/default as follow to disable power saving for PCI devices might work:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

So far so good after two days, but sometimes it doesn't happen for several days and then will happen very frequently. We'll see! Bummer that this is such a long-standing problem. 

Did anyone find any fix for this?  Its not bothering me in wayland as much as in x11.

@Ikshwak​ I gave up. I disabled the trackpad in the BIOS and was using a wireless USB mouse since Bluetooth didn't work either, and even then the machine would either die occasionally (i.e., screen goes blank after a period of inactivity, which is expected, but then neither the mouse nor the keyboard won't turn the screen back on), or the wifi would stop working, or the USB mouse would stop working. Cannibalized this thing for parts and it's going to electronics recycling. Not worth the headaches to keep messing with it.

@m2ee​ yeah, right? People save up money to buy these things with faith in the brand, and yet one of the most trusted brand fails to make good laptops let alone address the issue after these many years.
