Did you try “Battery Disconnect” in the BIOS? Just wondering if that is a different experience to a physical disconnect.
Also what OS/distrubtion?
Physical battery disconnect, and disconnect in bios… the bios didn’t seem to have a toggle in the menu item of disconnect battery.
Bios version 3.17
Running Fedora 37

I don’t recommend buying the LG Ultrafine 5K (or even 4K) to use with Intel Gen 11. It’s a glitchy mess and 3.17 BIOS nor the latest linux kernel has made any difference.

@nrp It does not work fine at all. I’m happy to help diagnose it but as it currently stands, 5K model is pretty much unusable and the 4K one decides to stop working here and there and takes a full shutdown to make it work again.
I’ve also had this issue the display 5k monitor and laptop combination never worked via USB-C. I’ve reached out to tech-support no solution, sent back my laptop immediately.
Here is the display model number I was using: 38WN95C-W
Display Product code: 38WN95C - WY.AUSOMPN
Framework laptop: 11th Gen i5-1135G7
Kernel: 6.2.6
Distro: Pop OS 22.04 LTS
Cable: [Intel Certified] Cable Matters 40Gbps USB4 Thunderbolt 4 Cable 2.6ft with 8K Video and 100W Charging - 0.8m - Backwards Compatible with Thunderbolt 3 Cable and USB-C https://a.co/d/2jGgHzk
Something to note: when I was testing it just now on BIOS 3.10, the display was constantly blacking out and restarting. I just updated to 3.17 and it is stable again.
Just want to note, that there are even worse problems with this display on the AMD Ryzen 7 7840U mainboard.
I have not done a thorough analysis yet, but it also seems to be power related in that with “lowish” (60% and lower ) battery and no other power source connected the display and power source cannot be used (no flickering, only errors in the kernel log).
It works (without any flickering and instantly) at least this time with sufficient battery, charging and a connected framework power source.
As soon as it does not charge from the framework charger anymore (80% battery as per firmware as configured in my BIOS), the display does not work. It still charges via the display though.
Using this same display with Ryzen 7840U on BIOS 3.03 and Fedora 39 - works pretty well. Charging and USB work OK and I get full resolution @120Hz. Only issue to speak of is random display whiting out
Sometimes it is most of the screen like this;
Other times it is half the screen. It will often flicker as I move the mouse.
I’m not using the Ultrafine 5K, but I can confirm that the 7840U with Ubuntu 22.04.3 works with the Apple XDR 32" at full 6K resolution (and scaling to 200%).
This is passing through the Caldigit Element Hub. I’m controlling the brightness using the Gnome extension vividshade - https://extensions.gnome.org/extension/6463/vividshade-multi-monitor-rgb-dimming-control/
@Kent_Brockman that looks like graphics corruption talked about here: [TRACKING] Graphical corruption in Fedora 39 (AMD 3.03 BIOS)
I read through this thread quite a bit before purchasing my AMD Framework 13, so I wanted to post here with my findings with the LG Ultrafine 5k (HMUB2LL/A) using the provided Thunderbolt 3 cable.
I tried to get this monitor to work on so many setups. NixOS w/ KDE Plasma would partially work; the display would show up as two separate displays that I could place side-by-side, but that solution didn’t work too well for me. I wanted it to act as one display.
I tried Ubuntu and got it to support full 5k in the demo environment, but later had problems after the full install. Not sure what happened.
Fedora 40 seems to be my answer. It supports full 5k and doesn’t split my monitor in two pieces, but only in gnome!
If anyone has fixes for other OSs, I would love to know.
