I’m with lenovo x1 extreme (nvidia card) that uses TB3 to connect to a dock (lenovo pro dock) and that goes to 2 external ultrawide monitors via DP.
Since updating to the 455 nvidia driver my setup is unusable.
if you standby it crashes
if you change any of the settings of the monitors, it crashes
if you undock it crashes.
Has anyone found a way to make it actually work?
It was working fine with 440, then popOS 20.04 (Ubuntu derrivative) auto-updated it to 455 and all those problems started happening.
I waited for popOS 20.10 with the new 5.8 kernel but unfortunately that didn’t fix anything.
And now I’m stuck with 455 because reverting drivers on popOS is non-trivial and now from my understanding 440 is not even supported by the new 5.8 kernel. So I’m stuck with working from the coach, since everything related to docking crashes…
