In general i have good experiences with thinkpads (t430s, t431, t460s, x220,x230) with intel graphics.
The t431 display did not work in the past, but beta4 is great.
Audio via HDMI is generally unsupported on every hardware for now, therefore i don’t feel the need to add it everywhere, also i don’t use that at all, but thanks for pointing out.
If you need audio over HDMI probably you can get it work via HDMI audio embedder/inserter hardware (it combines video signal with audio from 3.5 jack or other input).
They have different constraints than us. This makes sense when you want to secure apps from stealing each other’s data, but in Haiku, you have a lot more ways that would allow to do that without needing to go down as far as the CPU level. Starting with the fact that all apps run as root and have access to everything anyways.
So, that advice is valid where you would also use OpenBSD and do secure things, but on Haiku, not really?
Even the SD-card reader is working (it is attached via USB)
I have frankly no idea why the manufacturers insisting using pci based card readers in other laptops. PRobabyl cheaper than the usb ones?
TrackPoint (the red stuff) : works
TrackPoint buttons (the physical buttons above the touchpad): works
Touchpad : works, albeit it is recognized as a PS2 mouse, so no scroll and no touch sensitivity options in the preferences.
Physical right and left mouse buttons integrated in the bottom section of the touchpad (you have to press the touchpad and it clicks): works ok.
Tap and double-tap (tap lock to move windows or to select text): works
Brightness: hotkeys not working, but the slider is available in the Screen preference panel and it works, eg. it is possible to bind a keyboard shorcut to it using the Shortcut application.
Volume shortcuts: works
LAN/WLAN: works, albeit wlan doesn’t connects automatically.
Battery status: works
Main NVME and NVME in the WWAN port: works.
