BIOS

LENOVO 20U70006GE/20U70006GE, BIOS R19ET28W (1.12 ) 08/12/2020
secure boot aus

Ubuntu 20.04.1 64bit

Die Hardware (Ryzen 4000, L15-AMD Serie an sich) ist noch recht neu, daher gibt es wohl einige Kinderkrankheiten.

Kernel

Default-Kernel Ubuntu 20.04.1 ist 5.4 und daher relativ alt.

Direkt nach Installation: Linux L15 5.4.0-53-generic #59-Ubuntu SMP Wed Oct 21 09:38:44 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

"Edge-Kernel" (EK): Linux L15 5.8.0-28-generic #30~20.04.1-Ubuntu SMP Thu Nov 5 20:57:40 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Der -edge Kernel (5.8) ist aus den Standard-APT-Quellen verfügbar. Irgendwann gibt es dann auch 20.04.2 mit 5.8.

Weitere Option: "mainline"-Kernel oder selber compilieren?

Grafik

Internes Display tut direkt nach Installation (ebenso EK).

Externes Display?

Helligkeits-Regelung tut nicht direkt nach Installation: Tasten heller/dunkler funktionieren, aber die Helligkeit aendert sich nicht. Fix via EK!

3D-Beschleunigung?

Umschaltung Grafik <-> Consolen?

Sound

Sound-Ausgabe Lautsprecher und internes Mikrofon tun direkt nach Installation (ebenso EK).

Webcam

Funktioniert direkt nach Installation, ebenso mit EK (Test mit "cheese").

WiFi

Funktioniert, direkt nach Installation, ebenso mit EK.

LAN

Bluetooth

Funktioniert direkt nach Installation, ebenso mit EK.

WWAN / LTE

Gerät hat kein WWAN, daher keine Infos.

Tastatur

Direkt nach Installation (ebenso EK): Fn-Keys Mute ... Flight Mode: Tastendruck wird erkannt, UI reagiert (HUD-Anzeige).

Direkt nach Installation (ebenso EK): Caps-Lock / Num-Lock LED verhält sich normal (toggle ein/aus)

Trackpoint

Direkt nach Installation: tut, aber relativ schnell & zuckelig!? Fix via EK.

Touchpad

Direkt nach Installation: tut, aber zuckelig!? Fix via EK.

Suspend / Wake-Up

Direkt nach Installation Suspend scheint zu tun, wacht aber nicht korrekt auf: dunkler Bildschirm! Fix via EK!

MicroSD-Kartenleser

Fingerprint-Sensor

Tut nicht und laut Lenovo wohl auch nicht geplant.

Leistungsaufnahme / Power-Saving

SME / SEV

^ kernel has a dedicated quirk for it NVME_QUIRK_IGNORE_DEV_SUBNQN which (if set) will just ignore it instead of throw a scary warning.
Either way (quirk or warning), it then generate a "fake" subnqn that seem to do the same job save for being generic:

Warning just means those aren't registered to need that quirk yet (in drivers/nvme/host/pci.c), eventually it may just go away
when the list gets updated, end result will be the same. In other words, drives are fine

Ubuntu 20.10

Ist 20.10 zu bevorzugen gegenüber 20.04 - besserer HW-Support?

Falls ja: nur wegen neuerem Kernel oder gibt es auch im Userspace Anpassungen?
