http://bugzilla.opensuse.org/show_bug.cgi?id=1187566 Bug ID: 1187566 Summary: Display connected to Thunderbolt 3 Docking Station is not detected on cold boot Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: x86-64 OS: openSUSE Leap 15.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: eecdc3.opensuse@coders-haven.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I am using a HP Elitebook 1040 G4 notebook connected to a HP Thunderbolt 3 Docking Station, which in turn is connected to multiple USB devices and an external monitor via DisplayPort. Unfortunately, I am experiencing issues with this configuration as described below. I am using boltd from the hardware repository to authorize my Thunderbolt 3 Docking Station during startup. (Boot ACLs are not supported by my BIOS, as far as I can tell.) While devices connected to the docking station via USB will work afterwards, my external monitor, which is connected via DisplayPort, will not be detected automatically. Only when I manually reconnect the docking station after startup has completed, it will finally be detected (and awoken from standby). This leads me to believe that this issue is boot order related. (Previously, I was using openSUSE Leap 15.2 and a custom udev rule to authorize the docking station via sysfs and I did not experience this issue but the system would occasionally hang while booting instead. I have already tried the udev rule with openSUSE Leap 15.3 but this made the issue worse as the display was then only detected if I reconnected the external monitor itself.) Any help investigating this issue is appreciated as I do not have in-depth knowledge of the kernel or its Thunderbolt subsystem and cannot really make any progress towards a resolution on my own. -- You are receiving this mail because: You are the assignee for the bug.
