Standalone Operation

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• No
• Unsure (can check if relevant)

Describe the bug

Either screen by itself works fine. As soon as I plug in the second screen, both screens go black and disappear from the system's display configuration.

This only started happening after applying BIOS 3.08 EFI Shell update. Previously, I had applied BIOS 3.08 upgrade through fwupdmgr and I think didn't have the problem. I had never applied an EFI Shell update before, only updated BIOS using fwupdmgr.

Steps To Reproduce

Steps to reproduce the behavior:

1. Plug CableMatters USB4 Mini Dock into expansion slot 1
2. Plug first monitor into CableMatters USB4 Mini Dock (it works)
3. Plug in second monitor (both monitors stop working and disappear from the system's display settings)

Expected behavior

Both monitors work as expected.

Operating System

• OS/Distribution: Linux Mint Cinnamon
• Version: 22.1
• Linux Kernel Version: Linux work-laptop 6.8.0-71-generic #71-Ubuntu SMP PREEMPT_DYNAMIC Tue Jul 22 16:52:38 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

Additional context

Previously. both monitors worked at the same time with no issue. Originally, they even worked when they were plugged in at boot time. This broke some time ago (maybe due to an earlier BIOS update, but not sure which), external monitors have only been working if I plugged them in after boot.

Since the 3.08 release notes mentioned "Added Dual Display (Panel + External Monitor) support for pre-boot (BIOS/POST)," I thought that maybe it would fix the issue with monitors not working if they were plugged in at boot time. Since applying the update through fwmgr update didn't help, I thought to apply the EFI shellk update.

Unfortunately, that only made things worse, and now only one external monitor ever works. It still has to be plugged in after boot. I feel like every BIOS update makes the system less usable and consider downgrading as far as I can to regain functionality.
