https://bugzilla.kernel.org/show_bug.cgi?id=216728 --- Comment #41 from Mark Blakeney (mark.blakeney@xxxxxxxxxxxxxxxxxx) --- 1) I added that kernel option and rebooted. 2) With the lid closed, I suspended my laptop. 3) Pulled out the dock cable. 4) Opened the lid and waited the 60 secs before the lid display recovered. 5) Plugged the dock cable back in and this time both external displays, keyboard, and mouse recovered (although GNOME swapped the windows I had open on the 2 external displays?). Then captured dmesg which I have attached. I have not changed anything significant in the BIOS (not that I can recall). Note that I use fwupd often to ensure my BIOS and dock etc are always running the latest firmware. Dell updates both quite frequently and I am always running the latest. It was mentioned in that email thread that changing the BIOS thunderbird setting to "No security" helps alleviate this issue but I don't have any security options like that in my BIOS. -- You may reply to this email to add a comment.
