To describe the problems -
Well, it takes a few more milliseconds before what i typed could appear on the screen, this is making typing difficult as it is sometimes -
  • Skipping a few characters that i type
  • Continuously repeating the same character (like pressing j once types out jjjjjjjjjjjjjjjjjjj)
  • And also, i am using a wireless logitech mouse, the touchpad on my laptop doesnt work for some reason too. The two buttons work, but touchpad wont (i cant move the pointer or select something with the touchpad)

Your laptop is brand spanking new.
Current oem kernel is not close to be good enough for your machine.

Best thing you can do while on Linux Mint is to install the "mainline" kernel waiting for an updated Ubuntu oem kernel.
There has been an ubuntu PPA around for a while.
I can see there are also alternative methods to install mainline on Ubuntu-based systems.
No personal experience with any of them.

Patience with that machine on Linux. It will take some time for some components to work properly.

Hi!

Thanks for the reply, and I understand, I only purchased this laptop a few days ago.
However, before I try out your solution, could we please take a look at this?

https://bugzilla.kernel.org/show_bug.cgi?id=217406

The person here has the exact same pavilion 13, with ryzen 7 7735U as me. I'm convinced their problem was the exact same as mine.
They came up with a 'patch' where they change a very small part of the driver code.

So, could I receive some help on how I can apply this patch myself too? I can code but this is still a bit advanced for me... :(

I have looked at a few places in the file system itself, i dont think there is any C source code available... I only see either object files, or certain .ko files...
So maybe i have to download the kernel, insert the required source, and then take it from there.

Honestly never patched any kernel. It doesn't look too hard yet I'd rather leave it to those who know what they're doing. Hope someone with experience could come to your aid. It might have found its way to kernel already or it will be there any time soon.

Hmmm alright, so how do you think I would have to wait? (like a rough estimate) Also how will I be notified about when the updates come, and whether the update will support my hardware?

No idea. By the look of it I say it's almost there.
But you never know. Am not sure how laymen are treated these days on kernel email-lists,
if you let's say want to step in and ask for a "status update".

I have a solution but it may not be perfect and permanent. This problem is seen even in some 1 year old machines - HP Pavilion laptops.

Make sure to use the latest kernel.. currently it is 6.2.X.. With latest kernels, this problem is not seen much... it takes 30-40 seconds in login screen. There after it is ok.
