Need help diagnosing keyboard/touchpad/touchscreen issues

[tako-jerome]

edit : Gecko Rolling; update 11/3/2022
Brand new to Gecko and openSUSE generally, out of the box it's working quite well but I'm having an issue where, when typing, it's like the focus or selection (don't know the term sorry) is skipping all over the place. I'm using a samsung galaxy book pro 360 13", aka NP930QDB-KE01US, and this hasn't been an issue on any other OS I've demo'd (Ubuntu, Mint). I'll be typing, eg as I'm making this, or especially when running an alt+f2 command entry, and it's like the system wants to jump and try to input elsewhere on the screen. It's extremely glitchy trying to type, but aside from a sound card issue I've also had (and will post about later) the system is otherwise working fine.

This device has both a standard touchpad mouse and a touchscreen. I"m guessing one of them is too sensitive. Aside from playing around in the KDE system settings, are there any other ways I can try to roubleshoot this? I'm really hoping the answer isn't to just disable my touchscreen by default.

Edit 1 : I'll do my best to edit this and update as I can sneak research in during work today. Attached a screenshot of my touchpad settings - What are those ignored devices on the menu I can't access? Relevance? I tried increasing my keyboard timeout from 250ms (default) to 400ms and will report back later after typing more.

Hi there, is this with Rolling or Static ?

[geckolinux]

Great, glad it worked. It's just based on experience, I've experienced the same problem as the Linux software stack matures; the old method for supporting advanced touchpad features was xf86-input-synaptics , and more recently they have been moving to the newer libinput framework, but not all desktop environments adopted it at the same rate. Looks like I'll need to change this in the next release of GeckoLinux Rolling Plasma, so I'll file a todo bug report. Thanks a lot for this helpful report!

[tako-jerome]

I see, thanks. I am also trying to resolve an audio issue in which I can't get sounds through my internal speakers. It seems to be an issue with any Linux distro I try. I created a bug report, but should I make a post here too for the sake of documenting it here?

[geckolinux]

Thanks, regarding the sound issue, if it's present in other/all Linux distros then there's probably nothing that GeckoLinux can do to resolve it.

[tako-jerome]

Right, I don't expect you guys to write a driver, but if you can help me figure out which alsa packages I need or whether any aspects of the found solutions I linked to wouldn't translate to SUSE. You don't have to read that bug report though, I'll write as simple a description as I can in the morning. Basically I've found a few reported solutions but I've been unable to get them to work for me yet.

[geckolinux]

I understand. Please do let me know if any solutions appear, but from what I can tell it's an upstream issue with the kernel and/or ALSA on your hardware.

[tako-jerome]

Just an update - for a separate issue, I reinstalled Gecko KDE Rolling (KDE Tumbleweed), ran "zypper update", Kernel is 6.0.8-1-default, and tumbleweed release is 20221115, and I didn't have this issue. Then, curiously, I updated my KDE plasma appearance/theme, and set the display scaling to 112.5, restarted, and the issue reappeared. Removing that xf86 package again.
