Hi, Can anyoen help me identify what the issue could be as it related to my Laptop and monitor combo?
I have a 12 Gen Framework Laptop & LG40 as my external monitor but when ever i connect them via the USB-C thunder bolt cable. It connect via sound notification, the monitor screen turn on but then right after it turns off. the Charging signal on the battery flashes on and off also from my observation.
Today is my first using the laptop & monitor combo, I have downloaded all the updates from Framework. But if you don’t mind helping me through this I’d really appreciate your time.
The same external monitor connects without issues to another laptop via the same cable. (Hp Envy 360)
If you’re using Windows, make sure that you have installed the 12th gen driver bundle, and not the 11th gen (this seems to be something that has caught a few people. Otherwise, you could try connecting with an HDMI or DisplayPort cable, just to test that other solutions work, or you could try unplugging the USB-C card and plugging the cable directly into the mainboard (not a long term solution, but could lead you to a problem with an expansion card.) If all else fails and you aren’t able to get a response from any other users with this setup, you could also send a message over to support to see if they could help you out.
Yes I have updated to the latest drivers for the 12 Gen system. I can confirm this because on first power up 5 keys weren’t working along with keyboard gestures but after the driver update all keys began to work and the key board gestures…
The HDMI cable work without issues, but I am sure a lot of people would prefer a one cable setup just like what I am trying to do but then there is the current issue.
Yeah I reached out to support and the conversation has started. Will post the solution once I get it.

Try this:
…then just keep this in mind: The Framework Laptop is not TB4 certified. Also, nrp said the certification body didn’t have the relevant test cases at the time, and were developing the appropriate test cases. So, base on that, I, personally, took that as “It’s not TB4 on the Framework laptop”…and lowered by expectation.
Reach out to FW Support, maybe they know something that’s not publicly documented.

Yes @Second_Coming I have reached out to @FrameworkSupport on the issue. Also on reddit there is another person having a similar issueReddit post
Hi @Second_Coming no I wasn’t able to find a soltuoin yet, but the FW team sent over a link to Intel for me to test a thunder bolt3/4 driver.
I wont be ale to test this until friday.
If you have a Thunderbolt LG monitor with the same issue as mine, let me know how it goes for you.

Hi, Do you have any updates regarding this isssue? One year later, and I am having the same issue with the LG-35WN75C (usb-C monitor, rather than thunderbolt).
This display + dock used to work great with my XPS 9360 (thunderbolt).
I am using Fedora 39
Linux xx 6.6.6-200.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Dec 11 17:29:08 UTC 2023 x86_64 GNU/Linux
Framework 13 (AMD 7840u) 64GB RAM, 2TB. USBC expansion card in slot 1.
This monitor has an USB-C dock builtin with power supply. Every now and then, it disconnects and connnects again. Kernel log here:

Welcome to the community!
We recommend using HDMI or DP expansion cards for the best experience as that is hardware we control. Docks tend to be a bit of a mixed bag depending on how the dock. I always recommend pushing video through the HDMI or DP expansion cards as this is what we test against on Ubuntu LTS OEM C kernel and Fedora.
Looks like the dock is entering a power save state on occasion from your logs. Are you using TLP by chance?

Hi Matt,
My reason for buying this display was to have power delivery and display with a single cable (less cables is more space 
). I was surprised my XPS was able to work with it, as the thunderbolt was very buggy on linux.
I am not using TLP, but I have power profiles daemon installed. The problems occur on both Wayland and X11 and with usb c slot. PPD profile = performance.
Yesterday I was able to cause many display reconnects in succession (non-stop), this was when i launched a proton steam game.
Is there anything I can collect for you, if I am able to reproduce it?
Not sure what can be done as we do not actively test heavily against USB-C displays on Linux with docks, we recommend the expansion cards for HDMI and DP.
That said, my bigger focus would be to see if the USB disconnects happen on just the dock (which is outside of our control) or if this is happening with tested hardware like USB keys, a mouse or USB headset.
If the disconnects happen with those devices as well, then I would need to know:
- Intel 11th, 12th gen?
- Which BIOS version are you using?
- Are you seeing this on kernel 6.6.8?
