  • Ooh, I know this one! Here’s what I did to get it working and set so it survives a reboot:

    1. In a terminal, run sudo arandr
    2. Set all of the monitors to 1080p
    3. Close arandr
    4. Go to Settings > Display
    5. Rearrange monitors in correct order if necessary
    6. Set the each monitor to the correct resolution and frequency, applying the settings after each update
    7. All monitors should now work, BUT they will not survive a reboot in Pop-OS 22, because the GDM3 login screen will NOT have this information, and will reset everything. So we must copy the pop-os monitors.xml file to the gdm3 config directory:

    sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/

    Note: You may need to do this as sudo -i

    1. Reboot, and all 3 monitors should be loaded in the correct positions, at the correct resolution at the login screen


  • You may want to give it another shot. They’ve been working pretty hard to move away from config files - much more is done via the GUI these days to make things more user-friendly.

    The devs have also really been focusing on voice this year as well - it’s been really interesting to see what they come up with. A few releases back, they released an update that allows you to give voice commands to HA via a landline phone hooked up to a $30 VoIP box. There is also support now for Espressif’s new “S3-Box” devices, which have small screens, a speaker and a few microphones for under $50 - this does require messing with yaml files at this point, but I should be able to finally ditch my Echos soon!


  • You can easily have a smart home without any data leaving your home network.

    You need three things:

    • Home Assistant software (free and open source)
    • ZigBee (also free and open source) smart devices made by companies that comply with the ZigBee protocol
    • Most importantly, a ZigBee controller.

    There are several options available (Deconz Conbee II, etc), and this device gets plugged into the same machine Home Assistant is on, and it allows HA to control your ZigBee devices directly. No “hub” sending your data to a cloud server, everything is done on your local network. If the devices comply with the protocol, you don’t need their hub, even if they say it’s required.

    I use Hue bulbs, but have no Hue hub. I use many Aqara devices, but don’t have an Aqara hub. It’s pretty great and works very well!
