When you say it remains blank, do you mean the screen is totally powered off, or do you mean the backlight comes on but it just displays a black screen? Going from memory here, but I *think* in F29 (without Xen) the backlight would come on, but the screen was just blank, and I could make the caps lock light come on and hear sounds from the OS, and ctrl-alt-delete would cause it to reboot after 60 seconds as expected. Possibly a graphics driver problem. In Qubes R4.1 (F29-based) with Xen, when I resume I can hear the fans come on, but that's it. The backlight remains powered off, the caps lock light won't come on, sound doesn't resume playing, and I have to hold the power button to force reboot. Sounds to me like it could be a Xen panic, although I believe this is the same as what happened in F25, if memory serves. Also, I don't know what a debug card is, but my BIOS has an option called "USB Debugging" which is enabled. Do you know anything about that, or how to make use of it? I'm not looking to get into any serial/UART type stuff, but USB might be an option, depending on what it does, what you need to have, and how difficult it is. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
