continuous kernel messages
 

Hi displaylink,

using the latest version 1.2 you've just released, I get the following kernel message all the time. For example just while I'm moving my mouse.

Sep 20 11:02:47 chrysio kernel: [10229.738206] evdi: [W] collapse_dirty_rects:102 Not enough space for clip rects! Rects will be collapsedevdi: [W] collapse_dirty_rects:102 Not enough space for clip rects! Rects will be collapsed

I use a ThinkPad Carbon X1 with the Lenovo USB 3.0 Dock attached to two external Full-HD displays.

Thanks, we probably need to descrease the verbosity of the message.
As a workaround, you can change the default logging level of the module by creating a file
that contains
And then reboot. Other possible values can be looked up in evdi sources

Cheers,
Michal

Ok. That's stops the messages in kernel.log. Can't see them any more.

But I still have some rectangular regions on my external displays which have redraw problems. I thought this might have to do with the clipping rectangles.

What's your OS? Please attach logs so we know more about your setup.

Cheers,
Michal

My OS is:

Ubuntu 16.04.1 LTS / Linux 4.4.0-38 x86_64
