VMD was hiding, and Ctrl S revealed it, I am now typing from Firefox in a fully installed PoP!_OS.
VMD is new to me, is it something I need to re-enable now that Linux is installed?.
(AI search results are generally good for this kind of thing, but a couple of conflictions of opinion put me off trusting it)
Edit: Actually never mind, I reworded the question a few more times and got a better result ..
My bold. So I'm going with the safer option at the moment and leave it disabled, although I could try flipping it, see what happens, then flip it back if Pop!_OS doesn't like it. Hmm.It is generally recommended to keep the Intel Volume Management Device (VMD) controller enabled in the BIOS after installing pop!_OS, especially if your system uses an NVMe SSD, as VMD is designed to optimize performance, power efficiency, and stability for modern Intel platforms.
Disabling VMD can lead to issues such as the SSD not being detected, reduced performance due to fallback to legacy AHCI mode, or boot failures if the system relies on VMD for drive communication.
While VMD is primarily used for RAID configurations and Intel Optane memory support, it also enhances single-drive NVMe SSD performance and provides features like error isolation and hot-plug support, even when not using RAID.
Most modern Intel-based laptops and desktops (2020 and newer) use VMD, and disabling it without a specific need may cause problems.
However, if you are not using RAID or Optane memory and have no performance or boot issues, leaving VMD disabled may be acceptable. But if you encounter boot problems or SSD detection issues after installation, re-enabling VMD in the BIOS and ensuring the appropriate drivers are available during installation may be necessary.
For pop!_OS, which is Linux-based, note that Intel RST/VMD drivers are not supported on Linux, so enabling VMD may result in the system not recognizing the SSD unless the kernel includes native VMD support.
In such cases, keeping VMD disabled might be the safer option unless you are certain your system’s firmware and kernel support it.
In summary, unless you have a specific reason to disable it or are experiencing issues, it is generally recommended to keep VMD enabled for optimal performance and compatibility.
If you are unsure, consult your system manufacturer’s documentation or support for guidance specific to your hardware.
Edit: Also noticed Variable Refresh Rate in the desktop Display settings is set to Auto by default, switched it to off for now.
