[Bug 1789164] Re: Grub2 boot line indication out of sync on external monitor

[Phillip Susi]

That's really weird.  I didn't even think grub showed up on a second
monitor at all.  What if you press C to go to the command line and type
a few characters?  As you type do they show up differently?

Title:
  Grub2 boot line indication out of sync on external monitor

Status in grub2 package in Ubuntu:
  New

Bug description:
  The boot line indicator is out of sync on my external monitor
  connected via vga (Philips 241B6Q) with that displayed on my laptop
  (XMG/Clevo W230SS, nVidia GM107M). If I press the cursor down key, the
  indicator moves to the second line on my laptop screen, but not on the
  external monitor. If I press the cursor down key a second time, it
  moves on the laptop to the third line, and on the external monitor to
  the second line. The monitor thus displays the last but one state, so
  that the user frequently selects the wrong boot item. A screen shot is
  attached. This also happens in combination with other external
  monitors, so it is most likely a bug in the graphics system.
