Unfortunately this performance issue also affects my AMD-only laptop running Ubuntu 20.04 and my new docking station.
Is there any ETA for possible fix? |

My workaround has been to stay with Ubuntu 18.04 using the DisplayLink 5.3.1 driver for Ubuntu for the time being alongside the AMDGPU-PRO driver as that seems to be the only working configuration for me, but it's not ideal, especially considering I'm having to use the AMDGPU-PRO driver which has had compatibility issues with running software that works fine using the AMDGPU open-source driver. The lack of proper support for AMDGPU is what's keeping me from upgrading to Ubuntu 20.04 LTS and it seems like this issue has been brought up my numerous people for a few months now with no real answers or estimations on progress.  I would definitely advise DisplayLink to make their drivers fully open source, as many others have suggested over the past several years. That way, you know, us pesky Linux users wouldn't have to be so much of a bother.  I think it'd be to their benefit anyway, it's not like open source contributors would be seeing any of the profits DisplayLink makes and if anything it'll help to get their software available on more platforms which ultimately results in greater revenue for them.

I just realized that all displaylink developer replies were about "1FPS problem" when laptop screen is off. I failed to find any mention of screen lag for external monitors problem. Which is a little bit worrying me. Nevertheless we have vacations season rn, lets hope this topic will be addressed soon.
I could even live some time with lagging external screen, I can just display there some static things and mainly work on my laptop screen. But this problem also affects my laptop's audio, which gets some hiccups. I cant accept it unfortunately... Quote:

Without these workarounds, my external monitor exhibits high latency and really bad screen tearing. The monitor behaves fine with AMDGPU-PRO, so I doubt the fix is impossible. Hopefully some sort of update is given soon considering it seems to be affecting AMDGPU users as a whole and is likely keeping some, like myself, from updating to Ubuntu 20.04 LTS. |

But by accident I discovered something else, audio provided by the docking station is not as jerky as the native laptop's headphone output. Small win, I can now use the external screens to do some tasks Edit: It's not completely fine, I can still hear cracking when window displayed on the external screen refreshes it's content @any_displaylink_dev Are you aware of the performance issue on AMD systems running 20.04? I see that "1fps when laptop screen disabled" bug got some attention and there is a work going on it. I don't know if the problem I am facing is related to it or no. If you want I can provide more data Last edited by fitter; 09-10-2020 at 07:49 AM. |
