It's not the first time I write about cgroups, but a lot has changed since I wrote that post.

Some time ago I noticed that I could no longer boot a remote machine via Wake-on-LAN. This annoyed me quite a bit, as the machine was 2100km away and there was nobody at that location who could boot it for me. I really had no clue why it stopped working. So when I recently arrived at the location again, I started looking into it. Everything I had previously configured was still in place. The BIOS option Power On by PCIE devices was enabled, and I still had this in /etc/local.d/wol.start:

#!/bin/sh

ethtool -s eth0 wol g

echo "GBE" > /proc/acpi/wakeup

Yet, when I ran ethtool eth0, it showed that WOL was disabled:

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.

A few days ago, polkit version 0.113 was marked stable on Gentoo amd64. Since the update, I could no longer suspend my system without entering the root password. Quite annoying, especially for a laptop. When canceling the polkit dialog, this appeared in the journal (yes, I am using systemd):

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.
