[SOLVED] System update broke Displaylink / EVDI again

Looks like xf86-video-intel broke Displaylink again.
Plasma crashes on external screen activation, in i3 the screen does not update correctly I get a frozen screen on my displaylink device.
During research I found a bug report:
https://bugs.archlinux.org/task/64227?s … &closedto=
And also a reddit post
https://www.reddit.com/r/archlinux/comm … r/f30q3jr/
Current :
xf86-video-intel 1:2.99.917+893+gbff5eca4-1
Suggested driver in the reddit post:
xf86-video-intel-1:2.99.917+870+g6f4972d5-1-x86_64

What is the recommendation?
Do a bug report on the intel driver?

I'll try a downgrade for now, however it is not a permanent solution.

Thanks om before hand

Did a downgrade of the xf86-video-intel package.
xf86-video-intel-1:2.99.917+870+g6f4972d5-1-x86_64.pkg.tar.xz vorks flawlessly

Re: [SOLVED] System update broke Displaylink / EVDI again

--UPDATE--
decided to try out a few other tricks.
Temporarily disabling PageFlip for modesetting did work.
according to the documentation you should create the file:
/usr/share/X11/xorg.conf.d/20-displaylink.conf
I do like my systems clean so I made the file in the /etc tree instead:
/etc/X11/xorg.conf.d/20-displaylink.conf
added the contents:

------------------------------------------------
Section "Device"
  Identifier "DisplayLink"
  Driver "modesetting"
  Option "PageFlip" "false"
EndSection
--------------------------------------------
No need for using outdated drivers.

Confirmed works for me. My Symptoms were that the displays were working 90% but mouse was leaving ghost trails and pixelate under the mouse.

Hi Chico, you are awesome, I was scratching my head over this for a while, applied your fix and boom all good. Making my Monday back in the office alot smoother! I might add this comment to the AUR package to help others. smile

Re: [SOLVED] System update broke Displaylink / EVDI again

Have you tried removing xf86-video-intel and using the modesetting driver instead?


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: [SOLVED] System update broke Displaylink / EVDI again

Hi, sorry I need to clarify what you mean, my current setup (which has not changed) is as per the wiki below.

 

Install the displaylinkAUR driver. It allows configuring DisplayLink monitors using Xrandr in the same manner as the udl driver.
    Enable displaylink.service.
    Use the "modesetting" driver with AccelMethod "none" and MatchDriver "evdi".

Create a file with the following content:

/usr/share/X11/xorg.conf.d/20-evdidevice.conf

Section "OutputClass"
    Identifier "DisplayLink"
    MatchDriver "evdi"
    Driver "modesetting"
    Option  "AccelMethod" "none"
EndSection

So do I remove the intel driver completely via pacman -R xf86-video-intel ?

No need to remove the driver.
You do want your intel chip to work.
