The fingerprint reader now works with the latest fprintd from focal-updates , namely 1.90.9-1~ubuntu20.04.1 . Updated formula to use the built-in packages. If you’ve already ran the formula, pulling the latest and running it again will purge the prebuilt packages and install the Ubuntu-supplied ones.
WiFi also works without workaround with the latest kernel that just came into the update channel. The formula has been updated to remove the old workaround in case you ran it before. Same as with the fingerprint reader, pull the latest and re-run.
@Skye_Leake you can update the original post to say that WiFi and fingerprint reader workarounds are no longer needed as long as you get the latest updates for Ubuntu 20.04.
I concur @lightrush , I just upgraded my 20.04.3 system to the 5.13 kernel and now the wifi works without the need for the workaround. great news for getting a near turn-key LTS solution now. 22.04 is a few months away, but many might want to stay with 20.04 until a point release of 22.04 comes out.
Are sure about this? It was necessary a few months ago when they updated to Linux 5.13. I guess I’ll try enabling it.
EDIT: Seems like it works. I don’t see tearing after enabling it. I guess something got update between the first release of the 5.13 kernel and now.
EDIT 2: Nevermind. I still got the same partial screen update artefact during alt-tabbing as before with PSR enabled just now. Will keep the workaround for now.
@nrp I saw the guide for Ubuntu 20.04 and it looks great except for the mic jack workaround.
A better practice for modifying the behavior of kernel modules is to add a file in /etc/modprobe.d/ instead of editing an existing file. Modifying package-installed files will trip the package manager upon package upgrades into asking the user for manually choosing what to do with that file. If the user is applying the workaround by “just following instructions”, chances are they won’t know what to do when the APT asks them what to do with alsa-base.conf later on. Adding a separate file avoids that and encapsulates all needed changes into its own, hopefully well named file. Upgrades are easy and so is removal as it boils down to deleting the file.
That and also I think (almost certain but it wouldn’t hurt to double-check) the user has to run update-initramfs -u once they touch anything in /etc/modprobe.d/ as that needs to be backed in the initramfs.
I tried to comment there but my community login didn’t work.
I’m still seeing tearing having added i915.enable_psr=0 to my kernel params. I actually thought it was fixed until I started scrolling this page, then I could see it again! I’m on Ubuntu 20.04.4 (batch 9 laptop), Linux dove 5.13.0-37-generic #42~20.04.1-Ubuntu
The only other thing I’ve found doesn’t work is sound through HDMI. And (minor issue) I disabled the light sensor as it seemed to keep making minor adjustments that I perceived as flicker.
Thanks, interested in Ubuntu 20.04 instead of later version since some features in Ubuntu 20.04 is good for me (for example, Firefox driver version).
As for the guide ,
