I'm testing out Plasma 6 on a fresh installation and I think there are a

few workarouds and notes worth adding to the pkg readme.

- Move screen locking to its own section and mention xlock as an

alternative

- Mention about increasing resource limits, the default login class is

too conservative and most plasma widgets would keep crashing

- Mention about touchscreen calibration

Below is a new suggestion based on your feedback. I have also added a

new KDE PIM/Akonadi section based on the FreeBSD recommendation.

OK?

+Resource limits

+===============

+

+The "default" login-class resource limits are too conservative for KDE Plasma

+users. It is recommended to use the login-class "kde" for all KDE Plasma

+users.

+

+Depending on the application and if KDE widgets or plasmashell (you will find a

+plasmashell.core in your $HOME) constantly crash, the value must be set

+correspondingly higher.

+

+You can easily change the login class with the following command:

+

+# usermod -L kde your-user-name

+

+Touch screen calibration

+========================

+xtsscale(1) can be used for touch screen calibration, however it will not

+work under kwin, as a workaround, you can kill kwin first, calibrate your

+screen, then launch kwin_x11 again.

+

 Screen compositor

 =================

-The KDE compositor may not run properly by default. You can deactivate it

-under: "System Setting" -> "Display Configuration" -> "Compositor" or

-in `~/.config/kwinrc":

+KDE PIM and Akonadi

+===================

+KDE PIM applications like Akonadi, KMail, and Kontact use large messages on the

+local machine. The default size on OpenBSD is too small, which causes local

+connection issues, and Akonadi-based applications will be flaky (e.g. mailboxes

+do not display, messages cannot be found).

+Increasing the buffer size is recommended:

+# sysctl net.unix.stream.recvspace=65536

+# sysctl net.unix.stream.sendspace=65536
