Ubuntu 20.04 portrait mode issues with triple monitor dock

bushrat · 09-18-2020, 11:01 PM

Ended up posting this to the forums of the dock manufacturer https://support.plugable.com/t/ubunt...e-issues/19238 where they suggested trying newer NVidia drivers or reverting to Ubuntu 18.04.

Neither worked but I'm pretty sure I've narrowed the problem to actually being a problem with the NVidia driver as disabling that GPU and using the integrated graphics in conjunction with the DisplayLink connected side monitors seemed to work just fine.

See the other posting for a far more detailed description.

If you are not playing games on Linux, you should consider switch to the open-source nouveau driver instead.

That is how I did it.

Thanks for the suggestion. I'm not a gamer so I did consider using the Nouveau drivers but it's my understanding that they can't do CUDA which is required for my studies and programming initiatives.

I'm hopeful that nVidia releases something that is more compatible with DisplayLink in the near future.
