Hello Andrea, or anyone else affected,

Accepted evdi into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/evdi/1.12.0+dfsg-0ubuntu2~22.04.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hello Timo

I just tested version 1.12.0+dfsg-0ubuntu2~22.04.2. With this version the package installs without problem and my WavLink UG69PD2 is working as expected with two monitors attached via DisplayPort.

I attach the original apt-get upgrade error message, the generated evdi-dkms.0.crash error file and the apt-get install for evdi-dkms/jammy-proposed log.
