Seconding Actual. I've been self-hosting it for a while. You can also just use it as a standalone application on Windows and Linux. I update every week or so manually(you can also set up bank autosync or upload files exported from your bank), then I export a copy and back that up on an external HDD and upload to Filen.

I've been dual-booting Windows 11 and LMDE for a few months now on seperate drives. I've got secure boot enabled and have a Nvidia GPU. I've only had to go on Windows once to play a game from the Xbox app(I still have an active gamepads subscription) with my friends online.

It's been working fine for the most part. I haven't been able to get a second monitor to work properly again after disabling it in nvidia-settings shortly after installation. This has been a minor annoyance that I'm sure I could figure out with some effort.

After reboot it will ask for the password.

I got it working on LMDE6. If you are using secure boot you may need to mess around with that.

Did you generate keys? Or use keys already on the system? Also, is this Mint 20?
