Since I hate typing passwords all the time, I looked for a way to automatically unlock my SSH keys at login. This guide focuses on KDE Plasma 5 and SDDM, but it should be easy to implement it for KDE Plasma 4 and other display managers as well.

1. Start ssh-agent during login. This can be done in /etc/plasma/startup/agent-startup.sh.

2. Install and enable the kwallet PAM module to automatically unlock your KDE wallet during login.

While configuring my CalDAV accounts in Thunderbird on my new laptop, I ran into an issue. I have a few CalDAV accounts that are all on the same Zimbra server. Thunderbird only requested a login and password for the first account I added. It tried to open the next account I added with the credentials that were already stored for the first account, and that failed.

Many people I know use a laptop for almost anything, anywhere. When they arrive at the office, they hook it up to an external monitor, and use an external keyboard and mouse or trackpad. I prefer to have a proper workstation, with powerful CPU and GPU, lots of RAM and multiple large monitors. As it's rather difficult to take this setup with me to meetings, or when travelling, I still require a secondary device that I can take with me everywhere I go. Some people seem to be OK with a tablet for that purpose, but that just doesn't work for me.
