Ventoy Forums

I am new to Ventoy, although a longtime Linux user.
Does persistence in Ventoy preserve Wi-Fi settings
and screen shut off time or its lack in the power settings?
I've got about a dozen ISOs in my Ventoy USB, but even in Manjaro
Wi-Fi settings are not preserved between one session and the next
when I reboot.

Most Linux ISOs are LiveCDs - they don't have persistence.
You would need to set up persistence by adding a blank persistence file and then configuring Ventoy to use it with each particular ISO file.

If you dont understand, watch some YouTube videos or buy an eBook.
