Public bug reported: Ubuntu 20.04 LTS daily QA-test (live) on hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
Background: Another exploration of http://launchpad.net/bugs/1869571, primarily as I want screen dump to file bug upstream as requested; this box shares screens of hp 8200 that had it before, so I'd expect can easily re- create it.. (this box has menu on display I prefer, so maybe has cables reversed to hp 8200 used earlier) What I did: Opened `displays` to adjust to match setup (vertical alignment of screens); and on hitting "apply" the system has gone strange - black background (both displays) - lots of (white) flashing on mouse movements if near panel/dash - dash is gone, like it has background color but icons gone, now only ~half height of monitor (it was screen height before apply with icons) Menu items could no longer be operated as not viewable (let alone white flashes being very annoying) I pressed printscreen to get screencapture once `ubuntu-bug` was started; and the dash was re-drawn!!? (it was not there after screen position was changed & until printscreen was hit)... Printscreen also stopped all white-flashes, and the system is now operational again?
