Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Lubomir Stanko (stanko.lubomir)]

I have this exact same issue. I have connected two displays (RGB and HDMI cables) I've updated from Ubuntu 18.04 to 18.10. Everything was working correctly in 18.04.

Steps to reproduce:
Case 1:
1. Start docked laptop with displays connected in the docking station
2. Undock laptop
3. Redock laptop -> Freeze/black screen

Case 2:
1. Start docked laptop without displays connected in the docking station
2. Undock laptop
3. Redock laptop
4. Connect display (RGB or HDMI) in the docking station -> Freeze

Does this still happen to latest mainline kernel v4.20-rc7?

[Haug Bürger (haug-buerger)]

I'm currently running latest Ubuntu version and it didn't happen to me for quite some time now:

I can't recall with which update it went away, sorry.

I've updated the kernel to v4.20:
Linux citadel 4.20.0-042000-generic #201812232030 SMP Mon Dec 24 01:32:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

So far I've got no problem with docking and undocking. OS recognizes both monitors with no problem.

Hi,

I also find this message in Ubuntu 22.04 recently installed.

Can't see if it has any effect on my system.

This here is not a laptop but a desktop ( so no docking neither lid action ).
And this message does not show while booting in 20.04 on the same machine.
