@Robie,
For this updated source, package, I have compiled it for the 5.4 kernel on Focal, and confirmed that: a) The module now builds properly on 5.4 b) The module is loadable into the 5.4 kernel (without errors or warnings) The upstream evdi project itself is compatible up to kernel 5.9: https://github.com/DisplayLink/evdi/commit/83046d3e6e55de2069bada70894c633c090f7ddc So I suppose there is a potential for regression on the 5.4 kernel, and that would likely indicate an upstream bug in evdi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904654 Title: focal:linux-hwe-5.8 evdi-dkms build failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evdi/+bug/1904654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
