the wording (inherit from "default") doesn't correspond to the effective

declaration. you should have ":tc=default:" instead of ":tc=daemon:" on

the last line.

Hi Sebastien,

copy&waste err, fixed. I also fixed a typo and added a cap_mkdb example.

+Resource limits

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

+

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

+users. It is recommended to create a new login-class based on the "default"

+class for all KDE Plasma users. Here is an example for /etc/login.conf.d/kde:

+kde:\

+ :datasize=8192M:\

+ :openfiles-cur=2048:\

+ :openfiles-max=4096:\

+ :tc=default:

+

+Depending on your use-case and if KDE widgets or plasmashell keep crashing, the

+value must be set higher accordingly.

+

+You can change the login class for the user to be created with:

+

+# cap_mkdb -f /etc/login.conf.db /etc/login.conf.d/* /etc/login.conf

+# 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.
