I see the same problem on my Lenovo E595 (AMD Ryzen 5 3500U). I am running 20.04 with "5.4.0-29-generic" kernel.
I have not yet tried the "nomodeset" workaround that has been suggested so cannot confirm that yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873594 Title: sporadic black screen freeze on lenovo e595 Ryzen 3700U To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873594/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
