FBInk Initialization Failure on Firmware 3.25.1.1 (XOVI/Vellum install)

[wzjoriv]

I'm having trouble launching KOReader on my reMarkable 2 running the latest firmware (3.25.1.1). I installed KOReader (v2025.10-r1) via the Vellum package manager using the XOVI overlay.

When attempting to launch the script manually via SSH, the process aborts immediately with an FBInk initialization error.

Error Log:

reMarkable: ~/ /home/root/xovi/exthome/appload/koreader/koreader.sh
[FBDepth] Failed to initialize FBInk, aborting!
[FBDepth] Failed to initialize FBInk, aborting!
[CLI] Failed to initialize FBInk, aborting . . .

Device Details:

• Device: reMarkable 2
• OS Version: 3.25.1.1
• Installation Method: Vellum / XOVI
• KOReader Version: 2025.10-r1

It seems like the current FBInk binary/library included in this build might not be playing nice with the framebuffer changes in this OS version. Is there a specific flag I should use for 3.x firmware, or is a newer build of FBInk required for this kernel?

Any help would be appreciated!

This seems like a KOreader issue unrelated to Vellum in general, and specifically the cli wrapper.

From the readme:

• Issues with the software being packaged should be submitted to the relevant upstream
  projects, which are linked in the package index.
• Issues with the Vellum cli itself should be opened in this repository.
