Bug description

The laptop has two TVs connected as external monitors — one through a VGA port and the other through an HDMI port.
If the TVs are powered on after the operating system has booted, the laptop’s built-in keyboard loses functionality on the right Shift key.
An external USB keyboard works correctly.

Steps to reproduce

Boot the operating system

Turn on the displays

Check that pressing the right Shift key together with a letter produces a lowercase character

Expected behavior

The right Shift key should behave the same as the left one.

Additional information

Sometimes rebooting the system restores the keyboard to normal, and sometimes it doesn’t.
Same happens when using the command: sudo dpkg-reconfigure keyboard-configuration.
