Every now and again I’d connect my Soundcore Q30 bluetooth headphones to my ubuntu laptop and they would sound like garbage. I finally decided to look up what the deal was and found this.
The solution that worked is to edit /etc/bluetooth/main.conf
sudo nano /etc/bluetooth/main.conf
In that file, copy and paste this right under the [General] heading
# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
AutoConnect=true
Then search in that file for MultiProfile and change it from off to multiple
I was unable to start barrier after an update. The GUI would crash immediately. I tried running it in a terminal ( by running the command barrier directly) and got the error:
▶ barrier
Fontconfig warning: FcPattern object weight does not accept value [0 205)
[1] 8790 segmentation fault (core dumped) barrier
After installing progressive web apps on KDE, the icons don’t appear correctly in the task bar, like this:
That second app is Google Messages. This gets confusing, especially if you have applications grouped (which is the default option in Manjaro KDE). The fix is pretty simple and the solution is completely from here. I’m documenting it here, just in case.
First, you need xdotool. This can be installed in Manjaro like this
sudo pacman -S xdotool
Next you need to browse to ~/.local/share/applications/
It’s pretty easy to tell which desktop file is which, thanks to them having the appropriate icon.
Last step is to edit the Exec= line of the desktop file by appending this text:
I got my framework laptop today. I had intended to put Manjaro/KDE on it, but ended up with stock Ubuntu 21.04 (a story for another time). The trackpad is big and pretty nice, so setting up 3 finger swipe was an initial priority.
I didn’t have to do anything special to get the trackpad working. There were reports on reddit of it not working out of the box on certain distros. It’s a bit odd about how far you have to click to the right and to the left to get the respective clicks, but nothing too terrible.
For 3 finger swipes i went with Comfortable Swipe. The instructions are each to followo, but after giving permissions I had to do a full reboot. They claimed a log out would be sufficient, but was not for me. In any case, it works great.
— UPDATE —
For Manjaro/KDE I went with fusuma. The steps to install were roughly:
I ran this from the home directory to set it up to run on login (requires logout):
printf "$(which fusuma) & disown \n" >> .profile #.zprofile if using zsh
Right now my config has some things that don’t exist, but it got me the thing I wanted (moving workspaces with 3 fingers and moving windows with 4 fingers). I had to set a few of the shortcuts in System Settings > Shortcuts > KWIN
~/.config/fusuma/config.yml

I ran into a problem where Teams was stuck loading. On the few times I could get it to load, it would display an error page telling me to “Try Again” and to try “signing out”, neither of the links would do anything.
I was able to fix it by running:
pkill teams && rm -rf ~/.config/Microsoft/Microsoft\ Teams/Application\ Cache/Cache/*
Teams is kind of a disappointment on Linux. I have to use it, so hopefully that helps someone ( or me again in the future).
I hold the opinion that you can read into how a developer connects to their git repositories as a litmus test for other aspects of how they do things.
To “steel man” the usage of HTTPS. The obvious reason is that it’s easier to get started. People are familiar with username/password authentication and it translates directly here. The other big reason is port blocking on corporate networks. Port availability may not be within your control, and that could cause a headache.
I am going to assume a few things. 1. You are a developer 2. You aren’t oppressed with overly zealous corporate network security policies 3. You aren’t afraid of the command line
If those things are true, you may agree with me. Just because SSH is a tiny bit more effort to set up, it has many more advantages to authenticating with HTTPS. The biggest – the show stopper – reason is that those credentials unlock your entire account. If they are compromised in any way, you are completely left with your pants down. The number of times you communicate over the internet while developing, whether it be to fetch, pull, push, or anything else, you are risking exposure of those credentials. A compromised SSH key only provides access to the repositories. It can be revoked and a new one created. Do you have a credit card attached to your github account? Why would you risk the keys to your kingdom multiple times a day?
Once you have your SSH keys set up, it’s far easier to use and manage. There’s nothing to remember (unless you put a password on your key – even better security!). Once you are comfortable creating and managing keys, the applications for its use extend far beyond git repos. It immediately lends itself to server management and devops tasks.
The real reason Github recommends HTTPS over SSH is that it’s easier to support the lowest common denominator user. That’s not where I want to place myself, do you?
So what can you assume when you encounter a developer that uses HTTPS authentication?
Pros
Cons
– They read documentation. Github does recommend HTTPS in its setup guide.
– They are probably on Windows – They don’t use the terminal very often – They don’t do much server administration
While none of this speaks directly to the intelligence or capabilities of the developer, it does say things about experience and how deep they are down the tech rabbit hole. It also telegraphs the kind of experience you will have developing with them.
As a developer, I recommend switching to SSH authentication for your git repositories. You’ll learn a few things worth knowing, you’ll be more secure, and you’ll ascend beyond the mass market instruction set on network communication setup.

After I updated my desktop to Linux kernel version 5 when I logging in my network would disconnect/reconnect every 15 seconds or so. I wasn’t able to get on the internet. My ethernet cable was plugged directly into my motherboard and I don’t have wifi capabilities.
