Yes. Same issues happen when testing the HDMI port of the dock with that p= atch applied. > Do you have CONFIG_USB4_DEBUGFS_MARGINING=3Dy set in your kernel .config? No, CONFIG_USB4_DEBUGFS_MARGINING doesn't show up in /proc/config.gz=20 Tried a few more things to see if it would provide clearer details.=20=20 In Linux, the monitor connected to the dock detected correctly, which doesn= 't happen every time, setting the resolution to below 4k causes the monitor to display output. Before setting the resolution below 4k, the monitor would detect HDMI signal over and over without displaying video output. Booted to Windows and reproduced the issue of the monitor blinking on an off with the HDMI output on the dock. It did work after unplugging the dock and plugging it back in though. Didn't check the resolution though. If that is= an important detail, I can get it. Overall, both the Skip retimer scanning and 0001-thunderbolt patches cause = the dock to be correctly detected.=20 I'm not sure if I should pursue -- or how to pursue -- the other issues wi= th video. They seems sporadic. Amdgpu doesn't seem entirely stable. So maybe video issues are expected. --=20 You may reply to this email to add a comment.
