Here is a link with some issues concerning the USB-C Dock Gen2. I am waiting for an update to fix my issue since August 2020 (when I bought my T14 AMD). Lenovo released an update recently, but it didn't fix problem unfortunately. If I knew that I wouldn't be able to use my 4k screen for 8 months I would have returned it. I don't know why I paid 170€ for it. https://forums.lenovo.com/t5/Ubuntu/Lenovo-T14-AMD-Isses-with-external-screen-when-docked/m-p/5048223?page=1#5314300.

That 30 vs 60 Hz problem may be an AMD driver issue.

Not everything is a Lenovo problem.

 

Do you have any errors in your dmesg while switching to 60Hz ?

Well, if we want Linux support, we should do the opposite ;).

Buy the hell of machines claiming to support Linux and flood the

support with bug reports ;)

 

Jokes aside, someone is always the beta tester, however with people

like @MarkRHPearson I'm confident they'll sort it sooner or later.

 

Their BIOS need to improve in general, but there are parts Lenovo itself

cannot do much without the help and or cooperation from the company

owns the piece of HW isn't working, eg: firmware. Even if they have the code

and can fix themselves, the one or the order way the fixed firmware needs to be

approved.

 

Then there is the other problem, poor choice of HW for some boxes.

This is Lenovo's fault ofc, but there is hope to see Linux drivers at some point.

 

And lastly lack of vendor software support for Linux, which I personally don't need if the

the firmware adds functionality & the kernel supports the features :), but I understand

not everyone is a developer, and some people really want some GUI tools coming from 

the vendor.

 

Like I've said already in another thread, supporting another OS is not that easy,

and takes a bit of time, and a bit of time to have the internal infrastructure, hire

folks who understand the OS well, changing internal testing & certification(s),

and a lot more.

Human feelings, nothing you need to apologize for :). I get frustrated from time to time too, pretty normal.
