New Lenovo Laptop - No WiFi, Touchpad or Touchscreen

kw flag

I've just changed from a MS Surface Laptop 3 to a Lenovo Flex 5 14 (Ryzen 7530U). After installing both Ubuntu 22.04 and Kubuntu 22.04, I'm having issues getting some of the hardware to work, most likely because of it being newer. Is there a fairly straightforward way to install these missing drivers? I have been using Ubuntu for a while, but I never had any issues with drivers before changing my laptop. Currently, I'm attached to a homeplug using a USB network adapter. Not ideal, but at least I'm able to install updates and hopefully a driver fix!

Laptop - IdeaPad Flex 5 14ABR8
WiFi Adapter - Realtek RTL8852BE Resolved! Thanks to a post by @Jeremy31 Here
Touchpad - Unknown
Touchscreen - Unknown

Edit: Oddly enough, Bluetooth seems to be working.

Newest hardware tends to work best with newest OS. Have you tried 22.04

Hi David. My mistake. It is actually 22.04. Sorry about that!

I've now managed to get the touchpad working by downgrading the kernel to 5.19.0. The touchscreen is also working, but only single gesture mode it seems.

I also managed to get the WiFi working. I did this by installing the correct Linux Realtek driver available from Github. In my case, it was rtw8852be-dkms_1.0.0_all.deb.

The complete list of Realtek drivers can be found here: https://github.com/lwfinger/rtw89

Hopefully this will save someone else some pain :-)

I sit in a Tesla and translated this thread with Ai:

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.
