Just a bunch of customizations and tweaks I've made to my Linux workstation.
The tweaks to the LightDM display manager are under display/lightdm.
Copy everything in that directory to /etc/lightdm, and make sure it is
all owned by root. Make sure the Python script is executable by
root, and you have Python 3 in your path.
There are some scripts to ensure that WiFi works after the system
resumes from sleep or hibernate. They are located under power/wifi.
See the individual scripts for installation instructions, or run the
install.sh script.
When the VPN crashes, and the user is authenticated via Active Directory
(via Samba), then it can be difficult to recover. The VPN agent gets stuck
with a broken connection to the VPN. In order to sever that connection and
reset the VPN, sudo must be used. However, sudo attempts to contact the
domain controller over the broken VPN. This process takes a very long time,
both to prompt the user for the password, then to execute the command.
To help alleviate the difficulty, I tweaked the sudoers to allow recovery commands without prompting for a password:
$ sudo systemctl restart vpnagentd.service
$ sudo killall vpnagentd
One or both of these can be used to reset the VPN agent back to a state where the VPN can be reconnected. Since no password is needed, then executing the commands should be at least somewhat faster, and typing your password wrong won't extend the process.
To use, copy the file 'sudo/vpn' to /etc/sudoers.d/. Make sure the new file
is owned by root, and that permissions are 0440.
