Bug Description

When plugging in/out my external monitor (Acer B286HK) via an USB-C -> DP Adapter, there is a great chance, that the computer completely freezes. SysReq-Keys are also not working.

I added a kernel.log where you can see the boot-up after one crash, than plugging In/Out the monitor several times till a new complete freeze.

The graphics-card is the internal one of Core(TM) i7-7500Uin of the XPS13 MLK (9360).

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 v4.11 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.

Thanks for the helpful link. I tested the kernel v4.11 and this fixes the issue. Now, the Display is also running at 60 Hz (not 30 as it was before).
There are still some minor errors in kernel.log when plugging In/Out but everything seems to work.

It seems this is the same bug for Dell XPS 15 as well. Not always, but sometimes this happens either using the DA200 adapter (Type-C usb) or direct HDMI. However, a related bug has been fixed (black screen)* so I will report back if this still happens on the Dell XPS 15.
