If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done- noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed- noble-linux-oem-6.11'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Fix] Intel provides a patch to fix this issue https://gitlab.freedesktop.org/drm/i915/kernel/-/commit/9cb15478916e849d62a6ec44b10c593b9663328c [Test] 1. Install Ubuntu on LNL or ARL platforms 2. Connect 3 monitors on WD19DCS or WD22TB4 or WD25TB4 dock 3. Connect the dock to the machine 4. All 3 external monitors should display correctly [Where problems could occur] This is a workaround for certain intel GPU(Display version 14 ~ 20) to fix a firmware issue. It should not affect other unrelated platforms and most likely won't introduce any regression.
