Backups, Passwörter und 2FA abhängig voneinander

Hallo zusammen, ich bin gerade auf dem Weg, mich von der Abhängigkeit von Big Tech zu befreien und bin da in Gedanken auf ein paar Probleme gestoßen, wie die verschiedenen Dienste ineinander greifen und voneinander abhängen. Dazu folgendes Beispiel: Angenommen ich verliere mein Smartphone, auf dem Aegis für 2FA installiert ist. Die Aegis-Datenbank wird zwar auf meiner Nextcloud automatisch gebackupt, aber um mich dort einzuloggen, benötige ich den 2FA-Code vom Smartphone. Das Passwort zu der Cloud ist ausschließlich in Bitwarden gespeichert, wofür ich auch den 2FA-Code brauche. Falls ich noch irgendwo in der Cloud eingeloggt war und so an das Backup komme, benötige ich dann ja noch ein Passwort, um die Aegis-Datenbank zu entsperren. Wenn ich das zuhause auf einem Stück Papier aufgeschrieben habe, ist es natürlich nicht vor z.B. physischem Diebstahl oder Feuer geschützt. Wenn dazu noch verschiedene E-Mail-Accounts zum Passwort zurücksetzen dazukommen, die idealerweise auch über 2FA geschützt sind, wird alles nur noch komplizierter. Wie handhabt ihr das? Mit lokalen verschlüsselten Backups? Welche Passwörter merkt ihr euch und schreibt ihr die euch noch zusätzlich auf? Ich möchte möglichst ohne Tracking auskommen, mich dabei aber nicht aus Versehen aussperren.

Screen turns off for a second every now and then and mouse movement doesn't match witch display poll rate

Hello, I use Ubuntu 22.04.2 LTS and I got a strange problem without knowingly changing anything: Every now and then my primary display turns black for a second and then back on. My secondary display is working fine. My speakers are also connected to the display, so I'll hear a sound from them when it happens. I can't make out exactly what causes the turning off/on, but when I don't touch anything, it happens less frequently than when I'm working, switches windows, etc. Furthermore while my display works well with 144Hz refresh rate, my mouse input works at a noticably much lower refresh rate. I tried restarting my PC and replugging my DP-Cable and power cables. I'm relatively new to Linux so I don't know what the causes could be. I hope someone can help me :)

Selfhosting Location History

Hello, I'm looking for a good tool to selfhost some kind of location history similar to Google's one. To have some data I can test the tools with, I merged every of my bicylce and hiking tours to one GPX file containing 7000km worth of travel. Then I tried [this](https://github.com/luka1199/geo-heatmap) tool, but it really lags with so much data and every move and every zoom takes some seconds to load. Next I tried the "Phonetrack" app on my nextcloud instance, but this as well lags and I have to activate every track manually and they are color coded. I really like the connection between the phonetrack app on my Android and the nextcloud app, but I am afraid that I'll eventually run into the same performance problem when I gathered enough data. I've seen that theres OwnTracks, but it seems you have to set up your own server and I don't want to pay extra next to my nextcloud subscription. Do you know of any kind of location history tool I can use that can handle big amounts of data? EDIT: I now found a solution I'm very happy with: I still use the Phonetrack app with my Nextcloud and komoot to track my biking/hiking tours. I found a python program that downloads all my komoot tours (https://github.com/ThePBone/KomootGPX) in a folder on my Linux Desktop. I also mounted my nextcloud to my Linux filesystem, so I'd have access to the Phonetrack exports. I wrote a Java program that takes all the gpx files and converts them to a JSON file similar to the original Google Location History JSon file. That all happens automatically once in a week with an anacronjob. Finally I use this tool (https://github.com/theopolisme/location-history-visualizer) to visualize all the data. I've not run into performance issues with this unlike with the other apps I tried. I plan to change this program so I don't have to got through the steps with selecting the file, etc. but this is my current implementation that I'm very happy with. Just leave me a message if you need my Java file to achieve the same :)
