Would like to install HWE packages for my 20.04 Ubuntu, not sure if the kernel has been updated or not yet (to which there would be no point in doing for now).
How can I list what version of the kernel would be used by upgrading the HWE packages? OR Where can I find such info?
Thanks
I was upgrading my laptop from 16.04 to 18.04 using the do-release-upgrade command.
It downloaded everything and went about unpackaging things and installing them.
I was doing this in a virtual terminal (Ctrl-Alt-F6) and I had two graphical terminals open at the same time (F7 and F8).
The update froze—and I couldn't open any applications in either of my graphical terminals. The applications that were already open (Nautilus and Solitaire) worked fine, but nothing else. Switching to any other virtual terminal showed the same as F6, just a frozen update in progress with all the output there.
After attempting to get another shell (I couldn't), attempting to kill or suspend the update (I couldn't), open up Terminal in one of my GUI terminals (I couldn't), or just reboot or shut down from the GUI terminal (I couldn't), I held down the power button until the computer shut off, and started it up.
I got the Ubuntu splash screen, and a mouse that moves when I use the trackpad. Black screen otherwise. This is on terminal 7; switching to terminal 6 I get a text login prompt and can log in. /etc/os-release shows I have 18.04, but I don't have internet (of course) and running startx doesn't have any effect.
Also, the text that appears after I log in says "Welcome to Ubuntu 18.04.1 LTS" but goes on to say my Hardware Enablement Stack (HWE) is going out of support on 2023-04-30, and suggests I:
* Upgrade from Ubuntu 16.04 LTS to Ubuntu 18.04 LTS by running:
sudo do-release-upgrade -p
OR
* Switch to the current security-supported stack by running:
sudo apt-get install libwayland-egl1-mesa-hwe-18.04 xserver-xorg-hwe-18.04 linux-generic-hwe-18.04
and reboot your system.
I tried rebooting, and there was no change.
How can I get X working again and get a graphical login back? (Note: I usually use WiFi, but I do have an hard line and an Ethernet cable available if that would make things easier.)
(P.S.: I'm not sure what tags are relevant, so I only put a couple.)
I am so far unable to get Plex/ffmpeg to recognize the integrated GPU in my Core i7-8700 CPU. From my research it appears this is a common issue related to Coffee Lake CPUs, not just this specific model.
I started on vanilla Ubuntu 18.04, but also tried installing a mainline 4.17 kernel on 18.04, as well as upgrading to Ubuntu 18.10 with default kernel as well as latest mainline 4.18 kernel. None of these have resolved the issue.
Additional troubleshooting attempted:
usermod -aG video USERNAMEEditing /etc/default/grub with the following options:
GRUB_CMDLINE_LINUX_DEFAULT="splash quiet i915.alpha_support=1"
Later changed to:
GRUB_CMDLINE_LINUX_DEFAULT="splash quiet intel_pstate=skylake_hwp i915.enable_guc=-1 i915.alpha_support=1"
(using sudo update-grub after each change)
Confirmed integrated GPU is enabled in BIOS
Installed latest graphics drivers from http://ppa.launchpad.net/oibaf/graphics-drivers/
Followed the entire process to build QuickSync-enabled binaries from here
Nothing seems to be working. From what I've read, my current kernel version includes support for Coffee Lake graphics, but they simply are not recognized. Here are some additional details to aid in troubleshooting:
The error Plex logs when trying to use hardware transcoding:

I would really appreciate any help getting this working. Let me know if there's any further information you'd like me to collect.
Since upgrading to 18.04 from 16.04 I have been seeing the following message:

Does anyone know why this is happening?
I have upgraded to 18.04 couple of weeks ago and today found out my currently installed HWE is deprecated.
hwe-support-status --show-all-unsupported output is:
linux-image-3.19.0-59-generic libwayland-egl1-mesa-lts-vivid
linux-generic-lts-vivid xserver-xorg-video-all-lts-vivid
linux-image-extra-3.19.0-58-generic xserver-xorg-input-all-lts-vivid
xserver-xorg-lts-vivid linux-image-extra-3.19.0-59-generic
linux-image-3.19.0-58-generic xserver-xorg-core-lts-vivid
and hwe-support-status --show-replacements output is:
linux-generic-lts-xenial libwayland-egl1-mesa-lts-xenial xserver-xorg-lts-xenial
But when I try to install these packages, I get:
