Could you please test the following: - boot with CSM disabled - run sudo mokutil --set-verbosity true - reboot to the firmware and enable CSM - boot Ubuntu - report here any messages that appear on the console at boot time (take a picture and upload, or transcribe, etc)
After this, you can run 'sudo mokutil --set-verbosity false' to restore the previous behavior. ** Changed in: shim-signed (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799767 Title: ASUS Z170-A, shim 15+1533136590.3beb971-0ubuntu1: grub menu not showing with both SecureBoot and CSM enabled after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1799767/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
