Description

A few days ago version 21.0.1 of Mesa was released. When I try to connect a screen connected via the dock with this new Mesa version installed, I get error Configure crtc 3 failed.

If I try to use Sway (the i3 port in Wayland), I get the following error:

MESA-LOADER: failed to open evdi: /usr/lib/dri/evdi_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/dri)
failed to load driver: evdi

I can confirm, I have the same issue. I could fix the issue by downgrading mesa to 20.3.4 and rebuilding the evdi module.

Can confirm. Have a customer with the same issue, they would rather wait for a fix than downgrade mesa though.

This issue seems to be fixed in the latest release of evdi and DLM.

#275 (comment) @moodyhunter is it resolved for you as well?

[moodyhunter]

@bnavigator Unfortunately no, X complains there's no evdi_dri.so under /usr/lib/dri/.
My displaylink and evdi (evdi-git) is installed via the AUR package.

Name            : displaylink
Version         : 5.4-1

Name            : evdi-git
Version         : 1.9.1.r4.gb0b3d13-1

I sometimes get that error too on X (on both DLM 5.3 and 5.4). I try to setup a Displaylink monitor and it crashes because it cannot find evdi_dri.so. For me it is always fixed by either rebooting or by restarting X.

Sorry for the late reply, I upgraded mesa and it now works well, this was a false alarm.
