This lat= est > patch appears to have helped that issue, as my TB3 Lenovo dock on a > Framework 16 with an AMD 7840HS CPU is now able to use its display outputs > at the correct resolutions. I'll be testing with addition TB docks I have > access to in the near future as well. I suggest opening separate issue for this. I don't see how this patch could affect GPU reading EDID from monitor. Assuming it is over DisplayPort tunne= l, at that point the device router is already enumerated. This patch just spee= ds up the enumeration to cope with the Pluggable device internal timeout. Please attach full dmesg with "thunderbolt.dyndbg=3D+p" in the command line= too to that new issue. --=20 You may reply to this email to add a comment.
