Quick heads up since I’m putting out many fires today:
The latest Dell Inspiron BIOS update (version 1.11) has rendered an existing installation of Qubes OS inoperable. The disk password screen no longer shows up after initialization proceeds as normal, so now there’s just a blank screen. Unsure whether this is specific to Dell Inspiron 5593 or whether this is a wider issue.
Either way, the Dell 5593 has severe keyboard problems that seem common, according to forums–the keys on the lower two rows of the keyboard turn unreliable less than six months after purchase and with light use. Though the laptop was relatively easy to install Qubes on, I’d recommend avoiding this laptop.
Edit: It turns out this specific patch was supposed to have fixed one thing: “Reduced the event where the system displays a black screen.”
Edit 2: The Qubes Installation ISO no longer boots–black screen shows after initialization.
