SDDM Black Screen but ?Working Somewhat
Hello all,
This is my first time posting on the Kubuntu forums, as I just recently made a long-awaited transition to the wonderful world of KDE
I recently bought a System76 Oryx Pro V4, which came pre-installed with Pop!_OS. After purchasing the laptop, which came pre-installed with a 256 GB SSD, I added a 2 TB Seagate FireCuda SSHD (hybrid SSD + HDD) to expand the storage. After this, I wiped Pop and installed Kubuntu 18.04 on the system. Following the instructions at https://askubuntu.com/questions/1034...drives-ssd-hdd, I moved the home folder to the 2nd drive (the FireCuda). This process completed successfully, and after some NVIDIA driver updates was able to reboot without issue. So I was left with an intact system that was booting 2 full disk encrypted hard drives.
However, after updating my kernel version from 4.15.0-20 to 4.15.0-32, after unlocking the disk at the initial prompt, the session booted to a black screen without any visual information (including cursor). I could still switch to the other TTY's, and could manually login and run startx from there - successfully reaching my desktop without issues. If I use "Advanced Options" in the GRUB menu to bot into the old kernel version, I can unlock the disk and am presented with the normal login GUI. This continues to happen after the upgrade to kernel version 4.15.0-33.
On a hunch I tried typing in my password at the black screen and pressing enter (same thing I do when the login GUI is shown). Much to my surprise, the system successfully logged in, displaying the KDE logo on a black background as usual before successfully starting the desktop. This makes me believe that the source of the problem is SDDM. It appears that SDDM is running (confirmed when I switch to another TTY and run top, which shows the sddm process running) but not displaying any graphical information. I have tried purge uninstalling and reinstalling sddm/NVIDIA drivers, booting with nomodeset enabled, and deleting the .Xauthority file. I have no issue accessing my home folder on the 2nd drive. There is no config file to edit in /etc or /usr/lib/sddm, and the file in /var/log/sddm.log is empty. I have tried looking up all the help articles I can find with no avail.
This is my SDDM SOS - I need your help!
