Bug Description

I am using a new Dell XPS 17 with the latest Ubuntu (22.10). One bug I could see is the touchpad sensitivity. Sometimes, randomly, the upper part of the touchpad is the only one working, most of its surface does not work. If the movement starts in the working area, then you can use the whole touchpad until you lift the finger. After a while it seems to recover by itself. My feeling is that this is somehow related to the sensitivity of the touchpad (some instability) or related to the system that disables the touchpad while writing (again, some buggy detection). While writing this text I experienced the bug twice, for instance, intermittently.

In the past I have had multiple problems with the touchpad on the old laptops (Toshiba) and hoped these will disappear with a new one, but some seem to still be here. I am willing to do some deep debugging if someone shows me step by step (I am a simple user) how to do it. Or even allow someone to connect remotely if needed, but I really wish Linux & Ubuntu have a 100% reliable touchpad function.

Can you get the touchpad firmware version by the script?

P.S. please install i2c-tools before running it.

Thanks.

I tried running it and get an error. Tried both with Sudo and without (had "sudo apt install i2c-tools" before).

could you dump /proc/bus/input/devices? let me check why it doesn't work on your machine.

Thanks,

Checked the input devices list, the touchpad is on i2c bus 2.

Please use the command to dump the firmware version:

$ sudo i2ctransfer -f -y 2 w2@0x2c 0x20 0x00 r26

I'll ask Dell what is the latest firmware version for your machine.

Thanks,

reply #10,

The user reported the issue is ELAN, and according to the page, https://learn.microsoft.com/en-us/windows-hardware/design/component-guidelines/windows-precision-touchpad-required-hid-descriptors, the version number should be two bytes. Is it 0x01, 0x0c?

If so, can you guide the user to upgrade the touchpad firmware under Ubuntu?

Thanks,

Unfortunately, the touchpad firmware was not web post.
Could share the system's service tag? I know it's sensitive but could send to: <email address hidden>

I sent them to that email address you posted above. (I am not sure what are the possible implications and risks if I post it here)

The actual firmware get from the machine is 0x07 0x01. How do you identify it is the latest one. The mail that user send to Dell will contain HW info?
