From 52f872ec27fa9bcbcc33f7d97ac4416386316f8f Mon Sep 17 00:00:00 2001 From: Ollie Charles Date: Mon, 23 Nov 2015 14:45:26 +0000 Subject: services.xserver: Disable Ctrl+Alt+Backspace by default Ctrl+Alt+Backspace is usually enabled by default under X, and is a keyboard shortcut that forcefully kills the current X server. This can lead to data loss by users if accidentally pressed. This commit introduces a new option, services.xserver.enableCtrlAltBackspace, that is *disabled* by default. If set to true, the previous behavior can be restored. A similar decision was made by the Ubuntu team, and is documented here: https://wiki.ubuntu.com/XorgCtrlAltBackspace --- nixos/modules/services/x11/xserver.nix | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'nixos/modules') diff --git a/nixos/modules/services/x11/xserver.nix b/nixos/modules/services/x11/xserver.nix index 3348e8d0582c..fd862232e07f 100644 --- a/nixos/modules/services/x11/xserver.nix +++ b/nixos/modules/services/x11/xserver.nix @@ -409,6 +409,16 @@ in if possible.
