Using the Laptop 16 DIY, having followed the official instructions to install Fedora 40 with LUKS disk encryption.
Upon cold start of the device, the screen shows the Framework logo and dozens of randomly flashing vertical white bars and stripes. This occurs for about 4 seconds, until Fedora prompts for the LUKS password to decrypt the disk. That screen has no issues. All is well, from that moment on.
During a soft reboot (restart from running system), the issue does not occur.
After a force-off, during another cold start, Grub shows up with the same issue. Up until the LUKS prompt.
Is this a known issue, or went something wrong in assembling the device? It’s not a problem per se, but I’d like to know what’s going on under the hood.
I use encrypted drives on my (Ubuntu 22.04) virtual machines, which I believe use LUKS. Whenever I start them up, from scratch or by a reboot, I get either a completely blank screen or one with random garbage (like part of a giant mouse cursor), until I hit the ESCape key; then it switches to a text-mode prompt for the password. ESCape again switches back to graphics mode, and shows the proper prompt.
That behavior seems to be a bug. A pretty minor one, but I’m sure someone will be annoyed enough by it to track it down eventually.
