From 2657846fb2e47e8ba847b5ef6fe742466414c745 Mon Sep 17 00:00:00 2001 From: Ryan El Kochta Date: Wed, 23 Jan 2019 16:45:55 -0500 Subject: input-linux: customizable grab toggle keys This patch adds a new option to the input-linux object: grab-toggle=[key-combo] The key combination can be one of the following: * ctrl-ctrl * alt-alt * meta-meta * scrolllock * ctrl-scrolllock The user can pick any of these key combinations. The VM's grab of the evdev device will be toggled when the key combination is pressed. Any invalid setting will result in an error. No setting will result in the current default of ctrl-ctrl. The right and left ctrl key both work for Ctrl-Scrolllock. If scrolllock is selected as one of the grab-toggle keys, it will be entirely disabled and not passed to the guest at all. This is to prevent enabling it while attempting to leave or enter the VM. On the host, scrolllock can be disabled using xmodmap. First, find the modifier that Scroll_Lock is bound to: $ xmodmap -pm Then, remove Scroll_Lock from it, replacing modX with the modifier: $ xmodmap -e 'remove modX = Scroll_Lock' If Scroll_Lock is not bound to any modifier, it is already disabled. To save the changes, add them to your xinitrc.
