I am running 4.15.0-24-generic on a Lenovo X1 Carbon 6th Gen with the same specs, and I am also not able to connect to Dell Montiors at all. I work at home with a Hyundai (Hitachi) Monitor and it works pretty well, but on Dell U2415 (and another older Dell model) it does not work. The display won't get a signal (and xrandr does say no connection). I tried 2 different HDMI cables on both montiors and with an adapter from HDMI to usb-c/display port. No luck.

[Bug 1763202] Re: Lenovo X1 Carbon 6th Gen. HDMI not working for external monitor
> Did this issue start happening after an update/upgrade? I can't tell exactly. The system is just a week old, but I recall that there has been a kernel upgrade. HDMI had some issues (i.e. wouldn't connect) via Lenovo's docking station last week, it worked today though when connected to the notebook's HDMI port directly. I've tried with my somewhat aged (but okay) LG Flatron M2380D-PZ monitor, and there is some trouble: - The monitor is apparently detected when (the HDMI cable is attached and) the monitor is turned on: - The second monitor shows up in System Settings > Devices > Displays for about a second. Before that the notebook screen turns black for about half a second. - Then the second monitor disappears from the Settings again, and the external monitor shows "No Signal" That is an issue only since Ubuntu 18.04 (I can't tell whether it's related to a specific kernel), because the monitor used to work with my Dell XPS 13 Developer Edition, which is running the very same configuration of Ubuntu (18.04 LTS developer version) and behaves similarly now, until Ubuntu 17.10 not too long ago. I'm a bit reluctant building the latest kernel. If it's really really important I may give it a shot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763202 Title: Lenovo X1 Carbon 6th Gen.

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 v4.16 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.
