I press e and edit the boot command, then there is an instant reaction to the keyboard on all monitors, only the indicator in the main and sub- menu of grub seem to be affected.
I noticed that the sequence is at the moment slightly different then to what I originally described: cursor down one time -> indicator moves to the second line on the laptop but does not react on the external monitor, cursor down a second time -> indicator moves to the third line on laptop and on the external monitor as well. The indicator only lags when the cursor keys have been pressed an odd number of times. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789164 Title: Grub2 boot line indication out of sync on external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1789164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
