A subsequent reboot and the screen was as expected, the blocky-glitches on my-left-display were gone... System appeared normal and exactly as expected.
I also re-ran the install, this time into the other partition, and NO ISSUES occurred this time.. I can't see that I did anything different, as the displays are by default in the correct position, and all I change is the portrait-left tilt, which requires no guess work in KDE/Kubuntu as it's selected by picture and I hit apply. Either WAY what I consider an identical install (same box, just different partition using the same daily ISO) and THE ISSUE DID NOT RE- OCCUR ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933788 Title: post qa-test install, adjusting displays to match setup & display becomes blocky mess To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1933788/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
