→ Lock screen

xsecurelock is from far, the best screen locker out there.

and use lock.sh wrapper:

#!/bin/sh
XSECURELOCK_SHOW_DATETIME=1 XSECURELOCK_DATETIME_FORMAT="%A, %Y-%m-%d %H:%M" XSECURELOCK_PASSWORD_PROMPT=cursor xsecurelock

Also, in order to lock before suspend:

systemctl enable xsecurelock@parisni cat /etc/systemd/system/xsecurelock@.service

[Unit]
Description=Lock X session using xsecurelock
Before=sleep.target

Type=simple

→ Modes

Alt_gr is a good candidate for the mode key because it is accessible to the right thumb wich is probably the sronger finger we have.

To be able to set it, one way is to switch both Alt_R and Alt_gr and set $mod = Mod1.

An other good things is to get the caps_lock key do Escape, which is essential in vim/emacs key bindings.

All those changes can be set in the /etc/default/keyboard file:

XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT="altgr-intl"
XKBOPTIONS="caps:swapescape,lv3:lalt_switch,lv3:ralt_alt"

BACKSPACE="guess"
