Dell Monitor is flashing every 5 seconds
I just have installed Ubuntu last 3 days and my Dell Monitor 4K is flashing every 5 seconds using DisplayLink 5K. With Windows is not doing that behavior.
I installed DisplayLink USB Graphics Software for Ubuntu 4.4 but it stills keep flashing. Please your help. |

Hi
I was trying to reproduce the issue locally. With the same monitor, docking station and similar laptop (XPS 13 9360), however I haven't seen any blinking. Does you still experience that issue? I assume that you have done apt-get update && apt-get upgrade. Can you tell us what Xorg server version do you have? Or can you attach Xorg server logs? You can find them in ~/.local/share/xorg/Xorg.0.log By log analysis, I can say that this is likely to be XServer related issue as i don't see that DisplayLink device had any issues. In system logs I see that video 4 linux driver(videobuf2_v4l2 ) had some crashes. Can this be related? DisplayLink is not using that driver at all. But maybe 3rd party software does. Can you record a movie to show us what kind of blinking do you see? I would like to get also output of: dmesg -w > blink.txt while you are experiencing that blinking. Thanks in advance Łukasz |
