Arch Linux User Repository

Wow! I also experienced a dramatic drop in performance after the last update like @LinaM mentioned

Where can we submit issues to the developer? Is the github repo of evdi the correct place?

My system info is here, https://gist.github.com/MavropaliasG/3e8b84b39d324cb7a5b8f155ed3ac7d8

It appears that my last full system upgrade broke displaylink. xrandr --listproviders only gives the default provider with the name Intel, no longer any modesetting provider. How do I get the modesetting provider back?

I'm running linux-lts(5.10.29-1) with linux-lts-headers(5.10.29-1) installed. evdi seems to be properly loaded:

amicopo@Laptop:~$ lsmod | grep evdi
evdi                   73728  0
drm_kms_helper        278528  2 evdi,i915
syscopyarea            16384  2 drm_kms_helper,evdi
sysfillrect            16384  2 drm_kms_helper,evdi
sysimgblt              16384  2 drm_kms_helper,evdi
drm                   569344  8 drm_kms_helper,evdi,i915

The displaylink service is active but the monitors DVI-I-I-1 and DVI-I-I-2 do not show up in the output of xrandr (and arandr)

amicopo@Laptop:~$ systemctl status displaylink

I've been trying to resolve the issue but don't know where to look next. Hope someone here know's how to resolve this. Let me know if anyone needs more debug info I missed!

@bnavigator: install works on Manjaro with Kernel 5.11 + 5.12 now. Thx!

But now the performance is poor (slow) since the latest displaylink installation (amd renoir/ KDE). All was fine until kernel 5.10 and older displaylink (evdi 1.7.2)

The latest release of the PKGBUILD should now be compatible with Manjaro (pamac)

Manjaro on AMD Ryzen 7 hardware Kernel 5.11.10

EDIT: This was fixed by running sudo pamac build displaylink instead of using the pamac GUI. However, it still does not work with kernel 5.11, have to use 5.10 instead

I get the following error when trying to install in Manjaro using pamac (kernel 5.10.26), with evdi-git installed:

Any ideas?

Somehow after this update my screen is not recognized automatically. I had to load the evdi module in /etc/modules-load.d/evdi.conf

Yes, you need the headers for the kernel, which you build against. For the LTS kernel a manually updated evdi to the released version 1.9.0 would also work, I guess.

All of this is out of scope for the displaylink package. Please comment at evdi and evdi-git to get this sorted out.

@deimosfr I installed evdi-git manually and changed the linux-headers line to linux-lts-headers.

Thanks for the update @bnavigator.

Quick question, when trying to update, it requires linux-headers-5.11.11.arch1-1 however, I'm using the LTS kernel. Anything, I'm not sure it's going to work, any inputs on this?

Thanks
