Touchpad not working but showing up

gd flag

I know there are multiple questions like this but there was none that helped me till now. I have a Dell XPS 15 (the 2021 one)

I had the problem on Ubuntu 21.04 then I thought I'd update to 21.10 to fix everything but the problem is still there.

My touchpad isn't recognizing my touches, presses, moves, scrolls, etc. ... But if I input an external mouse, this mouse is working(but the touchpad obviously not).

But it is showing up in /proc/bus/input/devices which you can see here Although it does not look similar to all the Debugging tutorials I read. e.g. this one from ubuntu in this one it also writes at point 2. that I shall uninstall xserver-xorg-input-synaptics but this isn't even installed, I also am not able to get into the VT (?! never used) by pressing Ctrl + Alt + F2 but I'm able to get to a terminal without DE by pressing Ctrl + Alt + F7 as well as in xinput --list

If you want to know more information on my system to help me I'd be happy to share them.

Already thanks for your response

This problem went away by itself. As the author of this question wrote: *Did nothing and it somehow now works. I didn't restart, I just wrote the question and after I posted it it worked.*

Having the same issue, DELL098F:00 04F3:311C Touchpad stopped working suddenly out of nowhere. I have Dell XPS 17 2021 with Ubuntu 21.10 on it. Touchpad works in BIOS but not in Ubuntu.

So, I've finally fixed it by doing the following steps: 1. Turned the touchpad off in the settings. 2. Ran `sudo modprobe -r psmouse` and `sudo modprobe psmouse proto=imps`. 3. Rebooted the laptop. 4. Turned the touchpad on again, and it's worked. FWIW I tried all these steps separately before (turn on/off, reboot, bash commands), but it didn't help. Touchpad vendor is Elan.

Not related exactly to this question, but have your touchpad worked properly for last two months? I bought new XPS 15 9510 (2021) and my touchpad becomes laggy after some time of system usage (Ubuntu 21.10)

Yes it worked before and it works now again. I switched to Arch Linux where it worked too. Once again I had a problem with the touchpad but then I was able to fix it with a reboot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
