@jeff, Customer is working on your question. by the way, I input some comment from Aspeed.
ASPEED feedback update information: 1. ASPEED focus on Ubuntu LTS release 2. Ubuntu native 20.04 with 5.11.22 kernel doesn't support AST2600 miniDP display, there is no display in OS mode: workaround: it needs install ASPEED DRM driver:https://www.aspeedtech.com/support_driver/ 3. Root cause analysis is pointing to the ASP2600 miniDP driver(MPN:AST2600A3-GP) in Ubuntu kernel(native driver). I will attach the patch from ASPEED. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956398 Title: [Ruby Pass] Ubuntu with AST2600 mini DP Display doesn't work (OS Mode) To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1956398/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
