How to copy settings from one machine to another

homekdemigration

I would like to copy my "settings" from my desktop to my laptop. I am running KDE on Arch. I am not sure what to do with ~/.config, ~/.local, and ~/.kde4 since they have subdirectories with names that match my desktop hostname. If I naively copy everything, I get all sorts of errors/warning when logging in and trying to open my email/calendar/akonadi.

This is a really, really lame (non-)feature of KDE. ~/.config and ~./local actually do not have anything to do with it -- they are XDG standard filesystem hierarchy things used by various independent applications, not KDE.

After you install, get out of X (so KDE is not running) and try copying just your old ~/.kde/share/config in, then restart X.

If you have a hard time stopping X because of XDM and system services, you could try doing it in a VT while KDE is still loaded, just do not go back to X from the VT -- kill it on the command line to force a re-start (or just plain halt and reboot).

KDE – Using Sudo on GUI Applications in Arch Linux

This looks like an intentional configuration in Arch Linux. See this for discussion with links to solutions.

The best tip there seems to be adding "DISPLAY XAUTHORITY" to to the "env_keep" defaults in /etc/sudoers.

Fedora has in /etc/sudoers the following and this allows sudo somexapp to succeed.

Defaults    env_reset
Defaults    env_keep =  "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults    env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults    env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults    env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults    env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"

NetworkManager not auto-connecting to wifi on login

Connect to network with secret on boot

By default, NetworkManager will not connect to networks requiring a secret automatically on boot. This is because it locks such connections to the user who makes it by default, only connecting after they have logged in. To change this, do the following:

Right click on the nm-applet icon in your panel and select Edit Connections and open the Wireless tab

Select the connection you want to work with and click the Edit button

Check the boxes “Connect Automatically” and “Available to all users”

Log out and log back in to complete.
