Disclaimer: I used AI to translate my original text to make it more understandable. Original language was German. Hello again. I have a problem with the touchpad of this laptop: https://wiki.archlinux.org/title/Dell_XPS_13\_(9350)\_2024 The latest Dell firmware is installed. This is a fresh CachyOS installation with Niri. Default setup — no packages were added or removed during installation. Now the following happens: after a short time (1–2 minutes), the Elan touchpad loses the ability to click, perform gestures, and scroll. Only the cursor can still be moved. Also: Clicks, taps, gestures, etc are enabled in the config.kdl I’ve already tried to solve the problem all day — unfortunately without success. However, I did so with the help of an LLM. It suspects that the touchpad is being put into a sleep state by power-saving measures and no longer wakes up properly. The only thing that helps is a reboot where the components are reset by holding the power button. Then it works again for a few minutes. The attempts to fix this mostly involved kernel parameters: `i quiet nowatchdog splash rw rootflags=subvol=/@ root=UUID=2a167b84-4a2e-4060-a56d-3b1e335e5ace intel_pstate=active i2c_designware.disable_psm=1 irqpoll quiet nowatchdog splash rw rootflags=subvol=/@ root=UUID=2a167b84-4a2e-4060-a56d-3b1e335e5ace i2c_designware.disable_psm=1 acpi_rev_override=1 I’ve tried these variants. I’m currently testing the last one. With many suggestions from the LLM, side effects keep appearing, such as disappearing audio devices. I had the same problems with KDE. Back then the LLM suggested something that ultimately worked. I don’t remember exactly what — script and/or kernel parameters. That worked for months. But now with Niri/Noctalia I have no chance. Do you have any idea what the cause could be? Is the LLM even on the right track? Is this problem known? What also confuses me is that the Arch Wiki doesn’t mention any of that. There it looks like the touchpad works without issues. Could it also be defective hardware?
