[Solved] systemd-sysctl.service failed to set parameters from 99-sy...

Question

$ cat /etc/sysctl.d/99-sysctl.conf
# Protection from the SYN flood attack.
net.ipv4.tcp_syncookies = 1
# Disable packet forwarding.
net.ipv4.ip_forward = 0
# Tweak those values to alter disk syncing and swap behavior.
vm.vfs_cache_pressure = 1000
vm.swappiness = 0
# USB Speed
vm.dirty_ratio = 5
vm.dirty_background_ratio = 3
# KDE
fs.inotify.max_user_watches = 524288
$ cat /proc/sys/vm/dirty_ratio
10
$ cat /proc/sys/vm/dirty_background_ratio
5
but
$ cat /proc/sys/vm/swappiness
0
$ cat /proc/sys/vm/vfs_cache_pressure
1000
Only restarting of systemd-systct.service helps.
$ sudo systemctl restart systemd-sysctl.service
$ cat /proc/sys/vm/dirty_ratio
5
$ cat /proc/sys/vm/dirty_background_ratio
3

Solved with - % sudo chmod -x /usr/lib/pm-utils/power.d/laptop-mode

A more permanent solution is to mask that file
mkdir -p /etc/pm/power.d
touch /etc/pm/power.d/laptop-mode
which will not get written on update or reinstall. (Not than an update to this package seems at all likely but just in case.)
