Thunderbolt Mini DisplayPort to VGA cable not recognized

Hi,
     I have a Macmini5,1 1.0 that is running Arch Linux x86_64, kernel: 6.1.9-arch1-1. My main monitor is connected via HDMI, and I tried connecting a second monitor via a Thunderbolt Mini DisplayPort to VGA cable to the first-generation Thunderbolt port on the Mac Mini, but it's not detecting anything.

botlctl list, I don't get output

boltctl list -a                                                                                                                                                     :

I tried some additional things, for example: 'sudo boltctl monitor', but it remains suspended, and when I connect and disconnect the Mini DisplayPort, it doesn't recognize it. I also tried stopping and starting the service from systemctl, but it didn't make any difference. The second monitor is turned on, and when I had MacOS, the port was recognized and turned on the monitor.

Thanks a lot.
