KDE taskbar grouping not showing list

After a recent KDE upgrade, the taskbar grouping did not work anymore. Instead of e.g. a list of open files in gvim i had to click multiple times on the entry in the taskbar to cycle through the list of windows.

I couldn’t find the solution on google (most likely because I use the wrong terms to describe this feature) so here is a blog post to help people like me.

The solution: Right click -> Task Manager Settings -> Behaviour -> Clicking grouped Task -> Shows textual list.

Profanity IM cheat sheet

profanity IM is a nice XMPP client for the console.

Here is a list of commands, I can’t remember:

To answer a “authorization request” use

/sub allow user@jabber.service

This is article will be updated in case I have to lookup for another command….

UPC IPv6 prefix delegation and FreeBSD

Don’t believe the Connect-Box that you only get a /64 from UPC. Normal prefix delegation is possible, you just have to guess/experiment how big your prefix is. Here is my dhcp6c.conf

interface vr0 {
    send ia-pd 1;
    send ia-na 1;
#     send rapid-commit;

id-assoc na 1 {

id-assoc pd 1 {
 prefix ::/56 1800;

 prefix-interface vr1 {
   sla-len 4;

My rtadvd.conf:


Some excerpts from my rc.conf:


UPC/Magenta Fritzbox and IPv6 Prefix Delegation

I have started with the network migration today. There is now a fritzbox between the UPC ConnectBox and my router. For IPv4 this now means triple NAT \o/.

One of the most important task was to make my FreeBSD routers SSH port accessible from the internet.

What I have tried:

  • Wireguard: The FreeBSD go package uses SSE2 which results in an illegal hardware instruction. :-S
  • Reverse SSH: Yes it works. But I want something better.
  • IPv6: Following steps were necessary to get it working:
    • Disable the IPv6 Firewall on the ConnectBox
    • Enable IPv6 support on the Fritzbox
    • Disable “DHCPv6 Rapid Commit” on the Fritzbox.
    • Enable IA_PD and IA_NA on the LAN side of the Fritzbox
    • Configure my router as “Ipv6 Exposed Host” on the Fritzbox

Now what I have to think about: Do I trust the Fritzbox enough as a firewall?

Summer update

It is been 5 months since I last updated the blog.

So far no ECTS points for last term, due to some family problems. But the term started again, this time course on ottoman Palaeography.

Spent a great but expensive holiday in Greece.

Some payed traveling in September to Ireland, Croatia and Germany, year with the most flight miles since 2010. Due to some unfortunate events will be travel to Germany again next week.

While during summer I did lots of cycling to work. Unfortunately in September I got lazy again.

May Update

Noticed today that it has been 11 months since I returned to my current workplace. That means I have been back for longer than I had been away. Makes you think…

Apart from that busy in the hamster wheel. Some activities I should blog about elsewhere.

Just fixed a ‘502 Bad Gateway’ error on my blog. Seems to be php-fm isn’t as stable as expected. If this occurs again I will have to investigate further.

April Update

If you read this, I have switched my webserver from lighttpd, which I have been using for more than 8 years to caddy. Reasons: Built in Letsencrypt support. No longer dealing with spurious failures of the acme client. Config file looks really readable. Lets see how the memory footprint will develop. Also nar.arved.priv.at was updated to 10.4. There are still some maintaince tasks like switch from lighttpd’s spawncgi to php-fpm. But for now it seams I have working config.

March Update

Family off for family visit for two weeks. Unfortunately will not be able to make it through my long list of things to do. Work and university will take most of my time.
As the weather is quite bad, bought some swimming goggles, hope I will use them at least once.

This term at university I haven’t found a turkology course that I need and that doesn’t collide with other appointments. So this will be the last term for 18 EUR. Next term it will 380 EUR, so hopefully I will be able to study more serious to get more for my money.

Februrary Update

What happened:

Some changes in my network, I bought a Synology NAS, still trying to fill it up with various data on various machines. I bought a new Gigabit Switch, as the old one seems to be broken and I bought a new Accesspoint. The Ubiquity supports PoE which allows placement at a position where it covers the whole flat. Now I only need to get their management GUI unifi working on FreeBSD. Unfortunately my budget for Computer stuff is now finished, so no new Laptop until Summer 🙁

I am still struggling with my university assignments from last term. Next term it looks like none of the mandatory courses I need are offered, so I will probably take it easy.

Holiday plans have been made, looks like I will learn some Greek in summer.

The third incarnation of a BSD User Group in Vienna was launched. 2nd meeting is tomorrow, See BSD Stammtisch. Hope I will make it there.
