Is it possible to enable the external monitor of my notebook before the disk-encryption password is asked?
I’ve got a laptop with a Docking Station running Antergos with full hard disk encryption enabled. During boot, right after GRUB Menu. I have to enter the password to get antergos to boot.
The problem: At this state, my second monitor (attached to the docking station) is not yet recognized by the system. I have to open the notebook-lid, enter the password there, before I can work with my “usual” setup (External monitor, external keyboard).
I’m experiencing problems with my audio output, maybe someone here can help me?
I can hear sound through the speakers of my Notebook, but if I put it in my docking station, I get no sound through HDMI and no sound through the Headphone-Output on the docking station.
- Thinkpad T460p
- Thinkpad Ultra Dock
- Samsung SyncMaster external Monitor with HDMI
- Updated Antergos, Linux Mainline (because I have freezing issues with the default arch kernel)

Ah, one more thing:
There is a Firmware-Update for Ultra Dock available. It should fix “Screen flickering”, but nothing is mentioned about the other problems. Anyway, I would be interested, if this firmware might help.
Sadly, I don’t know how to install the firmware-exe without MS Windows, so I can’t test it myself.
Here is the link:
I also have the new T460p + Ultra Dock, and I’m experiencing exactly the same issues. Good to know, that I’m not alone… ;-)
I also have another issue: I can’t get audio to my monitor through HDMI. Do you have the same problem?
However, I upgraded to Linux Mainline Kernel, and this solved the issue 1.) with freezes on closing lid for me.
Issue 2.-4. are still present, but I guess if a fix is released, it will first be available in Linux Mainline. I also didn’t notice any drawbacks with Linux Mainline and can recommand it. But keep your original kernel as fallback!
